Specificity and accuracy are the keys to any successful Value-Based Care program. And clinical vignettes are a great way to learn.
Five years ago, the AAFP (American Academy of Family Physicians) published a crash course to educate family physicians on HCC coding. To this day, the clinical vignettes from this family physician HCC coding education course are still a great example of how and why family physicians need to diagnose specifically and code accurately in order to fully capture and treat the actual needs of their patients.
So if you are trying to educate family physicians on HCC coding, this Crash Course is a great place to start. As always, the M.E.A.T. criteria must be met in order to properly diagnose and accurately code any diagnosis.
What is the M.E.A.T Criteria in HCC coding?
-
- Monitor – signs, symptoms, disease progression, disease regression
- Evaluate – test results, medication effectiveness, response to treatment
- Assess – ordering tests, discussion, review records, counseling
- Treat – medications, therapies, other modalities
And here are the clinical vignettes presented in the AAFP’s HCC Coding Education Crash Course for Family Physicians:

When educating doctors on HCC coding, be sure to avoid common HCC coding pitfalls by remembering these rules:
• Use documentation and coding to capture the severity of illness/risk of high cost
• Make sure that you capture the complexity of the patient
• Major issues need to be captured at least once a year (clock restarts Jan. 1)

Need a real solution to train your family physicians on HCC coding for value-based care?
While this crash course is a great place to start, family physicians prefer to learn HCC coding and documentation for Risk Adjustment in the DoctusTech HCC coding education app. It is the only tool that consistently ranks #1 with both physicians and operators. Demo the app today.
What is HCC coding and why is it important for family physicians?
HCC (Hierarchical Condition Category) coding is the risk-adjustment method Medicare uses to predict future healthcare costs for patients. For family physicians, accurate HCC coding ensures appropriate reimbursement, reflects the true severity of patient illness, improves care planning, and reduces compliance risk. Because primary care captures most chronic conditions, family physicians directly influence RAF accuracy and value-based care performance.
Why did the AAFP create an HCC Coding Education Crash Course?
The AAFP created this course to help family physicians understand how HCC coding impacts risk adjustment, Medicare Advantage, and value-based care. The crash course uses practical clinical vignettes to show how specificity in diagnosis leads to more accurate RAF scores — which ultimately supports better patient care and organizational financial stability.
What is the M.E.A.T. criteria in HCC coding?
The M.E.A.T. criteria ensures diagnoses are clinically supported and audit-ready. M — Monitor: Signs, symptoms, disease progression/regression E — Evaluate: Labs, imaging, medication response A — Assess: Clinical assessment, reviewing records, counseling T — Treat: Medications, therapies, interventions A diagnosis must meet M.E.A.T. to be valid for risk adjustment reporting.
How do clinical vignettes help physicians learn HCC coding?
Clinical vignettes illustrate real-world scenarios where documentation specificity changes RAF scores. By comparing “baseline” vs “optimized” coding, physicians see exactly how diagnosing the underlying condition (not just symptoms) captures the true complexity of the patient. This makes coding education tangible, memorable, and clinically relevant.
What are common HCC coding mistakes family physicians should avoid?
Common pitfalls include: • Using unspecified diagnoses when a more specific one is clinically clear • Missing chronic conditions that require annual recapture • Failing to link complications or manifestations (e.g., diabetes + polyneuropathy) • Not documenting severity or chronicity • Forgetting that M.E.A.T. must appear in the note Avoiding these errors improves accuracy, compliance, and RAF scores.
