It tests risk adjustment model knowledge (HCC, CDPS, HHS-ACA), ICD-10-CM diagnosis coding accuracy, MEAT documentation criteria, and prospective/retrospective audit compliance. Candidates may use an ICD-10-CM code book during testing.

Sample CRC Risk Adjustment Coding Practice Questions

Try these sample questions to review concepts for the CRC Risk Adjustment Coding exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is the primary purpose of the CMS-HCC risk adjustment model?
A.To determine eligibility for Medicare Part A benefits
B.To calculate copay amounts for Medicare beneficiaries
C.To establish fee-for-service reimbursement rates for hospitals
D.To predict healthcare costs and adjust payments to Medicare Advantage plans based on patient health status
Explanation: The CMS-HCC (Hierarchical Condition Category) risk adjustment model is designed to predict healthcare costs for Medicare Advantage enrollees and adjust capitated payments to MA plans accordingly. Plans enrolling sicker populations receive higher payments, while those with healthier populations receive lower payments, ensuring fair compensation based on patient health burden.
2In the CMS-HCC model, what does the Risk Adjustment Factor (RAF) score represent?
A.The number of chronic conditions a patient has been diagnosed with
B.A numerical value that predicts a beneficiary's expected healthcare costs relative to the average
C.The total number of ICD-10-CM codes submitted for a patient in a calendar year
D.The quality rating assigned to a Medicare Advantage plan
Explanation: The RAF score is a numerical value that predicts a beneficiary's expected healthcare costs relative to the national average Medicare beneficiary (baseline of 1.0). A RAF score above 1.0 indicates the patient is expected to cost more than average, while a score below 1.0 indicates lower expected costs. The RAF score is derived from demographic factors and documented HCC conditions.
3Which of the following is a key difference between the CMS-HCC model and the HHS-HCC model?
A.The CMS-HCC model is used for Medicare Advantage, while the HHS-HCC model is used for the ACA commercial marketplace
B.The CMS-HCC model is used for the ACA marketplace, while HHS-HCC is used for Medicare Advantage
C.The HHS-HCC model only uses demographic factors, not diagnosis codes
D.The CMS-HCC model does not use hierarchies to organize condition categories
Explanation: The CMS-HCC model is specifically designed for the Medicare Advantage population, while the HHS-HCC model is used for risk adjustment in the Affordable Care Act (ACA) commercial marketplace. Both models use hierarchical condition categories derived from ICD-10-CM diagnosis codes, but they differ in the specific HCCs, coefficients, and populations they serve.
4What does the term 'hierarchy' refer to in the CMS-HCC model?
A.The order in which diagnosis codes must be submitted to CMS
B.The organizational structure of a Medicare Advantage plan
C.The ranking of related conditions so that only the most severe condition in a category is used for payment
D.The sequence of provider credentials required for documentation
Explanation: In the CMS-HCC model, hierarchy refers to the ranking of clinically related conditions within a category so that only the highest-severity (most resource-intensive) condition counts toward the RAF score. For example, if a patient has both Type 2 diabetes with complications and Type 2 diabetes without complications, only the more severe HCC is used for payment calculation, preventing double-counting of related conditions.
5How often must chronic conditions be documented and reported for risk adjustment purposes in the CMS-HCC model?
A.Once when first diagnosed, then never again
B.Every six months
C.At least once every calendar year
D.Only when the patient is hospitalized
Explanation: In the CMS-HCC model, chronic conditions must be documented and reported at least once every calendar year to be included in risk adjustment calculations. HCCs reset annually, meaning that if a chronic condition such as diabetes or COPD is not recaptured through documentation and coding in the current year, it will not contribute to the patient's RAF score, even though the condition is ongoing.
6A patient has documented diagnoses of Type 2 diabetes with diabetic chronic kidney disease (CKD) stage 3, and also Type 2 diabetes without complications. In the CMS-HCC model, how are these conditions treated?
A.Both conditions are counted and their RAF values are added together
B.Only the Type 2 diabetes without complications is counted since it was documented first
C.The hierarchy applies, and only the more severe condition (diabetes with CKD) is counted
D.Neither condition is counted because they conflict with each other
Explanation: The CMS-HCC model uses hierarchies to prevent double-counting of related conditions. When a patient has both a more severe and less severe form of the same condition category, only the higher-severity HCC is used for RAF calculation. In this case, Type 2 diabetes with diabetic chronic kidney disease is more severe and trumps the uncomplicated diabetes HCC.
7What are disease interaction terms in the CMS-HCC model?
A.Codes that indicate a patient has been referred to a specialist
B.Additional RAF value added when certain combinations of HCC conditions coexist in the same patient
C.Diagnosis codes that are automatically excluded from risk adjustment
D.Terms used to describe the progression of a single disease
Explanation: Disease interaction terms in the CMS-HCC model provide additional RAF value when specific combinations of HCC conditions coexist in the same patient. For example, a patient with both diabetes and congestive heart failure receives an additional interaction term on top of the individual HCC values. These interaction terms recognize that certain comorbidity combinations result in higher healthcare costs than either condition alone.
8Which demographic factors are included in the CMS-HCC RAF score calculation?
A.Age, sex, income level, and education
B.Age, sex, Medicaid dual-eligibility status, and institutional/community setting
C.Age, race, geographic region, and marital status
D.Sex, employment status, number of dependents, and zip code
Explanation: The CMS-HCC model incorporates demographic factors including age, sex, Medicaid dual-eligibility status (whether the beneficiary also receives Medicaid), whether the beneficiary is disabled, and whether they reside in a community or institutional setting. These demographic components form the baseline RAF score before disease HCCs are added. Income, education, race, and employment are not factors in the model.
9In the context of risk adjustment, what is 'suspect logic'?
A.A method used by the OIG to identify fraudulent coding patterns
B.An analytical approach that uses claims data and clinical indicators to identify conditions likely present but not yet coded
C.A process where coders suspect a diagnosis based on symptoms alone without provider documentation
D.A CMS algorithm that automatically removes unverified diagnoses from risk adjustment data
Explanation: Suspect logic (also called suspecting or predictive modeling) is an analytical process that reviews historical claims data, pharmacy data, and clinical indicators to identify conditions that are likely present in a patient but have not yet been captured through coding. For example, if a patient is taking insulin but has no diabetes diagnosis on file, suspect logic would flag this as a potential coding gap for provider review and documentation.
10What is the Medicaid Chronic Illness and Disability Payment System (CDPS)?
A.A Medicare fee-for-service payment model
B.A federal disability determination system for Social Security benefits
C.A quality improvement program for hospitals treating chronically ill patients
D.A risk adjustment model used to adjust capitation payments for Medicaid managed care plans
Explanation: The CDPS (Chronic Illness and Disability Payment System) is a risk adjustment model developed for Medicaid managed care populations. It uses diagnosis codes to categorize enrollees into clinical categories and adjusts capitation payments to Medicaid managed care plans based on the expected healthcare costs associated with their enrollees' conditions. It is separate from the CMS-HCC model used for Medicare Advantage.

Frequently Asked Questions

What is the CRC exam format?

The CRC exam is an open-book certification with 100 multiple-choice questions in a 4-hour window. Candidates must score 70% or higher to pass. An ICD-10-CM code book is the approved reference material.

What is HCC coding and why does it matter?

HCC (Hierarchical Condition Category) coding maps ICD-10-CM diagnosis codes to risk categories that determine payment rates for Medicare Advantage and other risk-adjusted programs. Accurate HCC coding directly impacts healthcare reimbursement.

What does MEAT stand for in risk adjustment?

MEAT stands for Monitor, Evaluate, Assess, and Treat. These are the documentation criteria that must be present in a medical record for a diagnosis to be considered valid for risk adjustment coding purposes.

What reference materials can I bring to the CRC exam?

AAPC allows an ICD-10-CM code book during the CRC exam. No other reference materials are permitted. Efficient navigation of the code book is essential for completing the exam within the time limit.

How should I prepare for CRC in 2026?

Focus on chronic condition coding (diabetes, COPD, CHF, CKD), HCC disease hierarchies, MEAT documentation requirements, and ICD-10-CM guideline application. Practice timed coding scenarios using your ICD-10-CM code book.

What careers does CRC certification support?

CRC holders work as risk adjustment coders, HCC coding specialists, chart reviewers, risk adjustment auditors, and coding quality analysts in health plans, physician groups, and coding service companies.
