A specialty coding certification for professionals who abstract and assign diagnosis codes for risk adjustment payment models, most commonly the CMS-HCC model used in Medicare Advantage. CRC-certified coders are trained to identify chronic conditions from clinical documentation, apply MEAT criteria, and ensure diagnosis coding accuracy that supports appropriate, compliant risk adjustment payment.
Who it's for
Medical coders, auditors, and health information professionals who want to specialize in risk adjustment coding for Medicare Advantage plans, ACOs, and other risk-based payment arrangements. Many candidates already hold a foundational coding credential (such as the CPC) before pursuing the CRC as a specialty add-on, though it can also be pursued as a standalone credential by those focused specifically on risk adjustment work.
What's covered
- ICD-10-CM Coding Guidelines — diagnosis coding conventions, specificity requirements, combination codes, and Excludes notes
- Risk Adjustment & HCC Methodology — how the CMS-HCC model works, RAF scores, hierarchies, and qualifying encounter/provider requirements
- Compliance, Documentation & Auditing — MEAT criteria, physician queries, RADV audits, and overpayment/compliance obligations
What to expect
The exam tests both technical ICD-10-CM coding skill and risk-adjustment-specific concepts that go beyond general diagnosis coding, including how to evaluate documentation for MEAT criteria and how the CMS-HCC hierarchy logic affects risk scoring. Many questions are scenario-based, presenting a documentation excerpt and asking candidates to determine correct code assignment or whether a condition qualifies for risk adjustment capture.
How to prepare
Because risk adjustment coding depends heavily on documentation review skill, not just code lookup, practicing with realistic chart excerpts and learning to spot MEAT criteria (or the lack of it) is more valuable than memorizing code lists in isolation. Understanding the CMS-HCC hierarchy logic conceptually — why certain related diagnoses don't stack — helps make sense of otherwise-confusing scenario questions.
