AHIMA CDIP Certified Documentation Integrity Practitioner Exam Practice Test

Creating policies and procedures for the query process will help eliminate confusion among CDI staff, providers, coders, and other stakeholders regarding the purpose, scope, format, and expectations of the query process. Policies and procedures should be based on industry standards and best practices, and should be reviewed and updated regularly.

A rebilling is permissible when queries are answered after the initial bill, as long as the hospital follows the appropriate guidelines and procedures for rebilling, such as submitting a corrected claim within the timely filing limit, notifying the payer of the reason for rebilling, and documenting the query process and outcome in the health record. Rebilling may be necessary to ensure accurate coding and reporting of the patient’s condition and treatment, as well as appropriate reimbursement and quality measures. [3][3] References: 1: https://www.ahima.org/media/owmhxbv1/cdip_contentoutline_2023_final.pdf [ 3][3]: https://my.ahima.org/store/product?id=67077

A query should be generated to ask the physician for the POA indicator of the fall because the documentation is unclear whether the fall was present at the time of inpatient admission or not. The POA indicator is used to identify conditions that are present or not present at the time of admission, and has payment implications for certain hospital-acquired conditions (HACs). According to CMS, a fall resulting in trauma is one of the HACs that will not be paid at a higher rate if it is not present on admission. Therefore, it is important to clarify the POA indicator of the fall to ensure accurate coding and reimbursement. A query should be non-leading, concise, clear, relevant, and consistent with CDI standards and guidelines.

 A pressure ulcer covered by eschar on the right hip is coded as an unstageable pressure ulcer, according to the ICD-10-CM Official Guidelines for Coding and Reporting. The guidelines state that “Pressure-induced deep tissue damage is defined as a pressure injury that is unstageable due to coverage of the wound bed by slough and/or eschar” 2. Eschar is a thick, dry, black necrotic tissue that obscures the depth of tissue loss and prevents accurate staging of the pressure ulcer 3. Therefore, the provider’s response of “unable to determine” the stage of the pressure ulcer is consistent with the definition of unstageable pressure ulcer. The code for unstageable pressure ulcer of right hip is L89.210 4.

According to the ACDIS Practice Brief, a query escalation policy should describe how to handle situations in which an answer is not received, an inappropriate answer or comment is provided, etc. The escalation policy should address when the issue is brought to the physician advisor, the department director, or administration with defined actions as to the responsibilities at each level. The policies should reflect a method of response that can realistically occur for the organization1. In this case, since two physicians have significantly lower query response rates than the target, the CDI physician advisor/champion should schedule individual meetings with each low-performing physician to provide feedback, education, and support. A group meeting with all physicians may not be effective or efficient, as it may not address the specific barriers or challenges faced by the low-performing physicians. A meeting with the chair of the gastroenterology department may be helpful, but it may not be sufficient to resolve the issue without direct communication with the low-performing physicians.

According to the AHIMA best practice for written queries, queries should be limited to non-leading questions that do not imply a specific answer or diagnosis, but rather ask for the provider’s opinion based on their clinical judgment and the evidence in the health record. Non-leading questions help to ensure that the query is compliant, objective, and respectful of the provider’s authority and autonomy. Leading questions, on the other hand, may introduce bias, influence the provider’s response, or compromise the integrity of the documentation and coding. For example, a non-leading query for a patient with chest pain would be: “What is the etiology of the chest pain?” A leading query would be: “Is the chest pain due to acute myocardial infarction?”

The coding reference that should be used for coding advice on correct assignment of the procedure code for proper ambulatory payment classification (APC) reimbursement is the AMA CPT Assistant. The CPT Assistant is the official source of guidance from the American Medical Association (AMA) on the proper use and interpretation of the Current Procedural Terminology (CPT) codes, which are used to report outpatient and professional services. The CPT Assistant provides clinical scenarios, frequently asked questions, coding tips, and updates on CPT coding changes. The CPT codes are used to determine the APC reimbursement for outpatient services under the Medicare Outpatient Prospective Payment System (OPPS). (CDIP Exam Preparation Guide)

A yes/no query may not be used in circumstances where only clinical indicators of a condition are present, and the condition/diagnosis has not been documented in the health record because it may lead to leading or suggesting a diagnosis that is not supported by the provider’s documentation. A yes/no query should only be used when there is clear and consistent documentation of a condition/diagnosis in the health record, and the query is seeking confirmation or denial of a specific fact or detail related to that condition/diagnosis. A multiple-choice, open-ended, or verbal query may be more appropriate to allow the provider to choose from a list of possible diagnoses, provide additional information, or explain the clinical reasoning behind the documentation.

An Excludes 2 note in ICD-10-CM indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes 2 note appears under a code, it is acceptable to use both the code and the excluded code together to completely describe the condition. For example, under code R05 Cough, there is an Excludes 2 note for whooping cough (A37.-). This means that a patient can have both a cough and whooping cough at the same time, and both codes can be used together to capture the full clinical picture.

A post-discharge query is needed to obtain a more specific principal diagnosis with the highest level of severity of illness (SOI) and risk of mortality (ROM) for this patient. The discharge diagnosis of health care associated pneumonia (HCAP) is not specific enough to capture the etiology, site, and severity of the pneumonia. Based on the clinical indicators in the case scenario, such as the history of aspiration, the chest x-ray findings, the elevated white blood count, the fever, and the antibiotic treatment, a more specific diagnosis of aspiration pneumonia would be appropriate. Aspiration pneumonia is a type of pneumonia that occurs when foreign material, such as food or vomit, is inhaled into the lungs, causing inflammation and infection. Aspiration pneumonia has a higher SOI and ROM than HCAP because it is associated with more complications and poorer outcomes 1.

Additionally, the discharge diagnosis of altered mental status is vague and does not reflect the underlying cause or severity of the condition. Based on the clinical indicators in the case scenario, such as the fever, the low sodium level, the moaning and disorientation, and the venous blood gas results, a more specific diagnosis of septic encephalopathy would be appropriate. Septic encephalopathy is a type of delirium that occurs when sepsis affects the brain function, causing confusion, agitation, or reduced consciousness. Septic encephalopathy has a higher SOI and ROM than altered mental status because it indicates a systemic inflammatory response and multi-organ dysfunction 2.

Furthermore, the discharge diagnosis of respiratory distress is also vague and does not reflect the underlying cause or severity of the condition. Based on the clinical indicators in the case scenario, such as the shortness of breath, the accessory muscle use, the respiratory rate, and the bilevel positive airway pressure treatment, a more specific diagnosis of acute hypoxemic respiratory failure would be appropriate. Acute hypoxemic respiratory failure is a type of respiratory failure that occurs when there is insufficient oxygen exchange in the lungs, causing low oxygen levels in the blood. Acute hypoxemic respiratory failure has a higher SOI and ROM than respiratory distress because it indicates a life-threatening condition that requires mechanical ventilation or oxygen therapy 3.

Finally, based on the clinical indicators in the case scenario, such as the fever, the elevated white blood count, and the antibiotic treatment, a diagnosis of sepsis should also be included in the query. Sepsis is a serious complication of infection that occurs when the body’s immune system overreacts to an infection and causes widespread inflammation and organ damage. Sepsis has a high SOI and ROM because it can lead to septic shock or death if not treated promptly 4.

Therefore, a post-discharge query should ask the provider to confirm or rule out aspiration pneumonia, hyponatremia (low sodium level), septic encephalopathy, and sepsis with acute hypoxemic respiratory failure as possible diagnoses for this patient. These diagnoses would result in a more specific principal diagnosis with the highest level of SOI and ROM for this patient.

A CDI steering committee is a group of interdisciplinary leaders who oversee and guide the CDI program’s objectives, outcomes, and metrics. The committee should include representatives from finance, clinical, coding, quality, and other areas that are impacted by CDI. The committee should meet regularly to review the CDI program’s performance, identify opportunities for improvement, and provide support and education to the CDI staff and providers. A CDI steering committee can help reinvigorate a stagnant CDI program by ensuring that it aligns with the organization’s vision and mission, addresses the current challenges and needs, and fosters collaboration and communication among stakeholders. The other options are not necessarily effective ways to reinvigorate a CDI program. Expanding the CDI program to larger areas in outpatient clinics may not be feasible or appropriate without a clear strategy and plan. Prioritizing to focus on efforts with the largest return on investment may not reflect the true value and quality of the CDI program. Identifying key metrics to develop program measures for coders may not capture the full scope and impact of the CDI program.

The entity that has the following regulation is the Centers for Medicare & Medicaid Services (CMS), which is the federal agency that oversees the Medicare and Medicaid programs and sets the Conditions of Participation (CoPs) and Conditions for Coverage (CfCs) for health care organizations that participate in these programs. The regulation that requires a medical history and physical examination be completed and documented for each patient no more than 30 days before or 24 hours after admission or registration, but prior to surgery or a procedure requiring anesthesia services, is part of the CoPs for Hospitals, which are located in 42 CFR § 482.24. This regulation was revised in 2007 to align with the Joint Commission’s standard and to provide more flexibility and consistency for hospitals and practitioners. (CDIP Exam Preparation Guide)

Aspiration pneumonia is a type of pneumonia that occurs when food, saliva, liquids, or vomit is breathed into the lungs or airways leading to the lungs, causing an infection or inflammation. Aspiration pneumonia is more likely to occur in people who have difficulty swallowing, such as those with a history of CVA2. In this case, the patient has a history of CVA and difficulty swallowing, and presents with nausea and vomiting, which are risk factors for aspiration. The CXR reveals a right lower lobe infiltrate, which is a common finding in aspiration pneumonia3. The physician documents pneumonia as the diagnosis, but does not specify the type or cause. Therefore, clarification is needed to determine if aspiration pneumonia is clinically indicated, as it would affect the coding and reimbursement of the case. Aspiration pneumonia is coded as ICD-10-CM code J69.x Pneumonitis due to solids and liquids, with a fourth digit required to specify the inhaled substance4.

This query option is the most compliant based on the most recent AHIMA/ACDIS query practice brief because it meets the following criteria:

• It is based on clinical indicators in the health record that support a reasonable and logical connection between the conditions (femur fracture and osteoporosis).
• It is non-leading and non-suggestive, as it does not imply a specific answer or diagnosis, but rather asks for the provider’s opinion based on their clinical judgment.
• It is concise and clear, as it uses simple and direct language that avoids ambiguity or confusion.
• It is relevant and specific, as it addresses a clinical issue that has an impact on patient care, quality reporting, and/or reimbursement.
• It is consistent with clinical documentation integrity (CDI) standards and guidelines, as it follows the AHIMA/ACDIS query practice brief recommendations for query format, content, delivery, and documentation.

A query should be generated when the documentation is conflicting, meaning that there is contradictory or inconsistent information in the medical record that may affect the accuracy of coding, quality reporting, or reimbursement. For example, if the documentation in the progress notes differs from the documentation in the discharge summary, or if different providers document different diagnoses or procedures for the same patient, a query may be needed to resolve the discrepancy and obtain clarification from the source of the documentation. A query should not be generated when the documentation is legible, consistent, or complete, as these are desirable characteristics of documentation that do not require further clarification or verification.

Query professionals should follow their healthcare entity’s internal policies related to querying, as they may vary depending on the organization’s size, structure, scope, and goals. The internal policies should be based on industry best practices and standards, such as those provided by AHIMA and ACDIS, as well as applicable laws and regulations, such as those from CMS and OIG. However, AHIMA’s and CMS’s policies are not binding for all healthcare entities, and they may not address all the specific situations and challenges that query professionals may encounter. Therefore, query professionals should be familiar with their own healthcare entity’s policies and procedures for querying, such as the query format, content, timing, delivery method, escalation process, retention, and audit. The other options are incorrect because they do not reflect the diversity and complexity of query policies across different healthcare entities.

The reference resource that should be used to obtain information about the signs and symptoms that are inherent to asthma is The Merck Manual. This is a comprehensive medical reference that covers various topics related to diseases, diagnosis, treatment, and prevention. The Merck Manual provides a detailed description of asthma, including its causes, risk factors, pathophysiology, clinical features, diagnosis, management, and complications. According to The Merck Manual, the signs and symptoms that are inherent to asthma are wheezing, coughing, chest tightness, and dyspnea (shortness of breath) 2. These symptoms are caused by the reversible bronchoconstriction and inflammation of the airways that characterize asthma. The Merck Manual also explains how these symptoms can be triggered or exacerbated by various factors, such as allergens, infections, exercise, cold air, stress, or medications 2.

According to AHIMA, clinical documentation is at the core of every patient encounter and it must be meaningful to accurately reflect the patient’s disease burden and scope of services provided. In order to be meaningful, the documentation must be clear, consistent, complete, precise, reliable, timely, and legible1. Reliability is one of the criteria for clinical documentation that means the content of the record is trustworthy, safe, and yielding the same result when repeated1. Reliability ensures that the documentation is consistent with the clinical evidence and reasoning, and that it can be verified by other sources or methods. Reliability also implies that the documentation is free from errors, omissions, contradictions, or ambiguities that could compromise its validity or usefulness1.

 One of the factors that an organization should consider when developing a query retention policy and procedure is if the query is considered part of the health record or not. According to the AHIMA/ACDIS query practice brief1, a query is considered part of the health record if it meets any of the following criteria:

• It is used to clarify documentation that affects code assignment or other data elements
• It is used to support clinical validation of a diagnosis or procedure
• It is used to support medical necessity or quality indicators
• It is used to communicate clinical information between providers If a query is part of the health record, it should be retained according to the organization’s health record retention policy and procedure, which should comply with federal, state, and local laws and regulations. The query retention policy and procedure should also address issues such as:
• The format and location of the query (e.g., paper, electronic, hybrid)
• The security and confidentiality of the query
• The accessibility and availability of the query
• The ownership and custodianship of the query
• The legal implications and evidentiary value of the query

According to the AHIMA CDIP Exam Preparation Guide, a modifier is a two-digit numeric or alphanumeric code that may be used in CPT and/or HCPCS codes to indicate that a service or procedure has been altered by some specific circumstance, but not changed in its definition or code1. One of the reasons to use a modifier is to indicate that a service or procedure was increased or reduced in comparison to the usual service or procedure2. For example, modifier 22 can be used to report increased procedural services that require substantially greater time, effort, or complexity than the typical service3. The other options are not correct because they do not reflect the purpose of using modifiers. A service or procedure performed in its entirety does not need a modifier, as it is assumed to be the standard service or procedure. A service or procedure resulting in expected outcomes does not affect the coding or reimbursement of the service or procedure. A service or procedure performed by one provider may need a modifier depending on the type of provider, the place of service, and the payer rules, but it is not a general reason to use a modifier. References:

A CC/MCC capture rate is a metric that measures the percentage of cases that have at least one complication or comorbidity (CC) or major complication or comorbidity (MCC) coded in the medical record. This metric is important for a CDI program because CCs and MCCs affect the severity of illness, risk of mortality, and reimbursement of the cases under the Medicare Severity-Diagnosis Related Group (MS-DRG) system. A higher CC/MCC capture rate indicates a more accurate and complete documentation of the patient’s condition and the resources used to treat them. A CDI program can use this metric to monitor the effectiveness of its queries, education, and feedback to the providers and coders. A CDI program can also compare its CC/MCC capture rate with national or regional benchmarks to identify areas of improvement or best practices 2.

According to the Documentation Integrity Practitioner (CDIP®) study guide, the physician with the highest number of unanswered queries would benefit from additional education. In this case, Dr. D has the highest number of unanswered queries with 9. Unanswered queries may indicate a lack of understanding, engagement, or compliance with the query process, which may affect the quality and accuracy of clinical documentation and coding1. Therefore, Dr. D would best benefit from additional education for unanswered queries, such as the importance of timely and appropriate query responses, the impact of queries on severity of illness, risk of mortality, and reimbursement, and the best practices for a compliant query practice2. References:

• Q&A: What to do with unanswered queries | ACDIS
• Guidelines for Achieving a Compliant Query Practice (2019 Update) - AHIMA

CMI is a metric that reflects the diversity, complexity, and severity of the patients treated at a healthcare facility, such as a hospital. CMI is used by CMS to determine hospital reimbursement rates for Medicare and Medicaid beneficiaries. CMI is calculated by adding up the relative MS-DRG weight for each discharge, and dividing that by the total number of Medicare and Medicaid discharges in a given month and year. Higher CMI values indicate that a hospital has treated a greater number of complex, resource-intensive patients, and the hospital may be reimbursed at a higher rate for those cases.

However, CMI is not the best measure of CDI performance, because it is influenced by many factors beyond CDI efforts, such as patient population, coding accuracy, documentation specificity, patient comorbidities, high volumes of highly weighted DRGs, and annual updates to relative MS-DRG weights. Therefore, measuring CMI over time with a focus on particular documentation improvement areas in addition to the overall CMI can provide a more comprehensive and meaningful assessment of CDI performance. For example, CDI programs can track CMI changes for specific DRGs, clinical conditions, or service lines that are targeted for documentation improvement initiatives. This can help identify the impact of CDI interventions on documentation quality, accuracy, and completeness.

A. Over time with a focus on high relative weight (RW) procedures that impact these procedures on overall CMI. This is not the best way to measure CMI as a metric of CDI performance, because it may not reflect the true complexity and severity of the patients treated at the facility. Focusing only on high RW procedures may overlook other documentation improvement opportunities for lower RW procedures or medical cases that may also affect patient outcomes, quality indicators, and reimbursement.

C. Month-to-month and focus on patient volumes to determine the raise the overall CMI. This is not a valid way to measure CMI as a metric of CDI performance, because patient volumes do not directly affect CMI. CMI is calculated by dividing the total relative weights by the total number of discharges, so increasing patient volumes will not necessarily raise the overall CMI unless the relative weights also increase.

D. Month-to-month to show CMI variability as a barometer of a specific month. This is not a reliable way to measure CMI as a metric of CDI performance, because month-to-month variations in CMI may be due to random fluctuations or seasonal effects that are not related to CDI efforts. Measuring CMI over a longer period of time can provide a more stable and accurate picture of CDI performance.

A query is noncompliant if it includes options that are not supported by the clinical indicators or the patient’s condition. In this case, hypernatremia is a condition of high sodium level, not low sodium level, and it is not consistent with the treatment of 0.9% saline IV. Therefore, it is a clinically irrelevant option that may confuse or mislead the provider. A compliant query should only include options that are reasonable and plausible based on the available documentation and evidence. (CDIP Exam Preparation Guide)

In order to best demonstrate the impact of clinical documentation on severity of illness and risk of mortality, examples from the hospital’s actual cases are the most effective for physicians in a hospital. Examples from the hospital’s actual cases can show how specific documentation elements, such as diagnoses, procedures, complications, comorbidities, and present on admission indicators, can affect the severity of illness and risk of mortality scores of the patients, as well as the hospital’s performance and reputation. Examples from the hospital’s actual cases can also provide feedback and education to the physicians on how to improve their documentation practices and standards. References: : https://www.ahima.org/media/owmhxbv1/cdip_contentoutline_2023_final.pdf : https://my.ahima.org/store/product?id=67077

Educating physicians on severity of illness and risk of mortality is best accomplished by using case studies that demonstrate how documentation affects these indicators and how they impact patient care, quality outcomes, and reimbursement.

A query should include relevant clinical indicators from the health record that support the need for clarification and the query options. Clinical indicators are objective and measurable signs, symptoms, laboratory results, diagnostic test results, medications, treatments, and other documented findings that are related to a specific diagnosis or condition. Information from previous encounters, the impact on quality, and the impact of reimbursement are not appropriate to include in a query, as they may introduce bias, lead the provider, or imply a desired response.

The proper sequencing of the principal and secondary diagnoses in this case is as follows:

• Principal diagnosis: Acute appendicitis. This is the condition, after study, that occasioned the admission to the hospital, according to the ICD-10-CM Official Guidelines for Coding and Reporting. The patient was admitted for laparoscopic surgery, which is a definitive treatment for acute appendicitis. The physician documented “possible acute appendicitis or probable Meckel diverticulitis” as the cause of the right lower quadrant abdominal pain. According to the AHA’s Coding Clinic, Fourth Quarter 2016, pp. 147-148, when a physician documents two diagnoses connected by “or”, coders should query the physician for clarification if possible. However, if a query is not possible or not answered, coders should assign codes for both conditions, unless one of them has been ruled out or confirmed by further testing or treatment. In this case, there is no indication that either acute appendicitis or Meckel diverticulitis has been ruled out or confirmed by further testing or treatment. Therefore, both conditions should be coded and reported. However, only one of them can be the principal diagnosis. Since acute appendicitis is more commonly associated with laparoscopic surgery than Meckel diverticulitis, and since it has a higher relative weight than Meckel diverticulitis under the MS-DRG system, it is reasonable to select acute appendicitis as the principal diagnosis 23.
• Secondary diagnosis: Right lower quadrant abdominal pain. This is a sign or symptom that is associated with the principal diagnosis and requires clinical evaluation, therapeutic treatment, diagnostic procedures, extended length of hospital stay, or increased nursing care and/or monitoring. The patient presented with right lower quadrant abdominal pain as a manifestation of acute appendicitis or Meckel diverticulitis. The pain required clinical evaluation by abdominal ultrasound and therapeutic treatment by laparoscopic surgery. Therefore, it should be coded and reported as a secondary diagnosis 4.
• Secondary diagnosis: Type I diabetes mellitus. This is a chronic condition that affects the patient’s care in terms of requiring diagnostic or therapeutic services or affecting patient outcomes or resource utilization. The patient has a history of type I diabetes mellitus and received an injection of neutral protamine Hagedorn insulin to normalize the blood sugar level prior to surgery. Therefore, it should be coded and reported as a secondary diagnosis 4.

The first step in changing a departmental workflow is to assess the current workflow and identify the problems or inefficiencies that need to be addressed. This will help to define the gaps and solutions, set realistic timelines, and re-engineer the process.

The first step the CDI director should take is to gather data on the incidence of inaccurate record documentation because it is important to establish the baseline and scope of the problem, as well as to identify the potential causes and consequences of over-using electronic copy and paste. Data collection can help to measure the frequency, severity, and impact of documentation errors, such as inconsistencies, redundancies, contradictions, or omissions. Data collection can also help to determine the best methods and tools for conducting the documentation integrity project, such as audits, surveys, interviews, or software applications. (CDIP Exam Preparation Guide1)

The correct diagnostic related group (DRG) assignment for this case is 469 Major Joint Replacement or Reattachment of Lower Extremity with MCC. This is because the principal diagnosis is primary osteoarthritis of right hip status post uncomplicated total hip replacement, which belongs to the Major Diagnostic Category (MDC) 08 Diseases and Disorders of the Musculoskeletal System and Connective Tissue. The DRG 469 is assigned to cases with this MDC and a surgical procedure code for major joint replacement or reattachment of lower extremity. The secondary diagnosis of aspiration pneumonia due to choking on liquid episode qualifies as a major complication or comorbidity (MCC), which increases the relative weight and payment for the DRG. The MCC is determined by applying the Medicare Code Editor (MCE) software, which checks the validity and compatibility of the diagnosis codes and assigns them to different severity levels based on the CMS Severity-Diagnosis Related Group (MS-DRG) definitions manual 2.

According to the AHIMA CDIP Exam Preparation Guide, a query is a communication tool or process used to clarify documentation in the health record for documentation integrity and accurate code assignment1. A query should be clear, concise, and consistent, and should include relevant clinical indicators that support the query1. A query should also provide multiple choice answer options that are supported by clinical indicators and include a non-leading query statement2. In this case, the patient has a large right lung pleural effusion related to lung cancer stage II, which is documented multiple times. However, the documentation does not specify whether the pleural effusion is malignant or not. A malignant pleural effusion is a condition where cancer cells spread to the pleural space and cause fluid accumulation3. A malignant pleural effusion is a major complication or comorbidity (MCC) that affects the severity of illness (SOI) and risk of mortality (ROM) of the patient, as well as the reimbursement and quality scores of the hospital4. Therefore, a post discharge query opportunity should be sent to the physician to clarify whether the pleural effusion is malignant or not, based on the clinical indicators such as chest x-ray, thoracentesis, and fluid analysis. The query should provide answer options such as malignant pleural effusion, non-malignant pleural effusion, unable to determine, or other. The other options are not correct because they either do not affect the SOI/ROM of the patient (A and C), or they do not address the specificity of the diagnosis (D). References:

 Severity of illness (SOI) and risk of mortality (ROM) are two metrics that measure the complexity and acuity of a patient’s condition, based on the number, nature, and interaction of complications and comorbidities (CCs) and major CCs (MCCs). SOI reflects the extent of physiologic decompensation or organ system loss of function, while ROM reflects the likelihood of dying. Both SOI and ROM are divided into four levels: minor, moderate, major, or extreme. These metrics are used to adjust payment rates, quality indicators, and performance measures for hospitals and other healthcare providers.

If a CDIP stops reviewing any record after a major CC is found, they may miss other CCs or MCCs that could affect the patient’s SOI and ROM levels. For example, a patient with pneumonia and sepsis would have a major CC (pneumonia) and an MCC (sepsis). If the CDIP stops reviewing the record after finding pneumonia, they would not capture sepsis, which would increase the patient’s SOI and ROM levels from major to extreme. This would result in underreporting the patient’s true complexity and acuity, and potentially lead to lower reimbursement, lower quality scores, and higher denial risk.

Therefore, the unintended consequence of this policy is a decrease in SOI and ROM levels for patients who have more than one CC or MCC.

Reviewing and analyzing physician query content on a regular basis assists in identifying gaps in skills and knowledge of the clinical documentation integrity practitioners (CDIPs) and the providers. By evaluating the quality, accuracy, appropriateness, and effectiveness of the queries, the CDIPs can identify areas of improvement, education, and feedback for themselves and the providers. Reviewing and analyzing physician query content can also help to ensure compliance with industry standards and best practices, as well as to monitor query outcomes and trends2 References: 1: https://www.ahima.org/media/owmhxbv1/cdip_contentoutline_2023_final.pdf  2: https://my.ahima.org/store/product?id=67077

According to the AHIMA CDIP Exam Preparation Guide, a second-level review is a process that involves a review of coded records by a designated person or team to ensure the accuracy and completeness of coding and documentation1. A second-level review may be triggered by various factors, such as high-risk or high-dollar accounts, coding quality indicators, payer requirements, or internal audit findings1. One of the factors that is most likely to trigger a second-level review is a record with multiple major complicating conditions (MCCs)2. MCCs are diagnoses that significantly affect the severity of illness and resource utilization of a patient, and are assigned a higher relative weight in the DRG system3. A record with multiple MCCs may indicate a complex or unusual case that requires additional validation and verification of the coding and documentation. A record with multiple MCCs may also affect the reimbursement, risk adjustment, and quality scores of the hospital, and therefore may be subject to external scrutiny or audit4. The other options are not as likely to trigger a second-level review, as they are not as indicative of coding or documentation issues or risks. A procedure code that increases reimbursement may not necessarily require a second-level review, unless it is inconsistent with the documentation or the clinical indicators. A diagnosis that impacts a quality-of-care measure may be relevant for CDI purposes, but not necessarily for coding validation. An account coded before the discharge summary is available may be incomplete or inaccurate, but it may also be corrected or updated before final billing. References:

facilities must develop an escalation policy for unanswered queries and address any medical staff concerns regarding queries1. If a query does not receive an appropriate professional response, the case should be referred for further review in accordance with the facility’s written escalation policy2. The escalation policy should address when the issue is brought to the physician advisor, the department director, or administration with defined actions as to the responsibilities at each level1. The policies should reflect a method of response that can realistically occur for the organization1. Therefore, reviewing the facility’s query policies and procedures is the best approach to ensure compliance and consistency in handling unanswered queries.

The other options are not advisable because they either involve skipping the escalation policy, notifying the physician advisor/champion without proper review or feedback, contacting the physician repeatedly without respecting their time or availability, or notifying the coding team without resolving the query issue.

The first step that a clinical documentation integrity practitioner (CDIP) should take to determine the present on admission (POA) status of a stage IV sacral decubitus ulcer documented in the discharge summary is to review the history and physical (H&P) because it is the initial source of information about the patient’s condition at the time of admission. The H&P should include a comprehensive physical examination that covers all body systems, including the skin. If the H&P documents the presence of a stage IV sacral decubitus ulcer, then the POA status is “yes”. If the H&P does not mention the ulcer, then the CDIP should look for other sources of documentation, such as wound care notes, nursing notes, or progress notes, to see if the ulcer was identified or treated during the hospital stay. If there is no clear evidence of when the ulcer developed, then the CDIP should query the attending provider to clarify the POA status. (CDIP Exam Preparation Guide)

A strategy that should be part of a project aimed at improving the unacceptable documentation behaviors of some physicians is to add a physician advisor/champion to the CDI team. A physician advisor/champion is a physician leader who supports and advocates for the CDI program, educates and mentors other physicians on documentation best practices, resolves conflicts and barriers, and provides feedback and recognition to physicians who improve their documentation. A physician advisor/champion can help change the documentation behaviors of some physicians by using peer influence, credibility, and authority to motivate them to comply with the CDI program goals and standards. A physician advisor/champion can also help bridge the gap between the CDI team and the physicians, and foster a culture of collaboration and quality improvement 23.

The coding reference that should be used to access the general rules for the ICD-10-CM Includes Notes and Excludes Notes 1 and 2 is the ICD-10-CM Official Guidelines for Coding and Reporting. This document provides the conventions and instructions for the proper use of the ICD-10-CM classification system, including the definitions and examples of the Includes Notes and Excludes Notes 1 and 2. The document is updated annually by the Centers for Medicare & Medicaid Services (CMS) and the National Center for Health Statistics (NCHS), and is available online at 2. The other coding references listed are not specific to ICD-10-CM or do not contain the general rules for the Includes Notes and Excludes Notes 1 and 2.
