Is F41.1 an HCC code?
F41.1 has no mapping under the current CMS-HCC V28 community payment model. F41.1 has a separate mapping under the Part D RxHCC model (HCC 133 (Anxiety and Other Psychiatric Disorders)); the applicable result needs member context.

HCC Category Mapping
These are source-labeled model coefficients, not member totals. A category may still be removed by hierarchy or model cleanup rules. Weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member context, hierarchy and cleanup rules, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains available for historical review.

MEAT review for F41.1
For F41.1, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule.
- MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
- EEvaluate: test results, medication response, or physical findings reviewed by the provider
- AAssess: explicit mention in the assessment or plan with acknowledgment of status
- TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis

What This Code Means
F41.1 is the ICD-10-CM diagnosis code for generalized anxiety disorder. Generalized anxiety disorder is a condition where a person experiences persistent, excessive worry about various aspects of daily life for at least six months. F41.1 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering anxiety, dissociative, stress-related, somatoform and other nonpsychotic mental disorders (f40-f48).
F41.1 has no mapping under the current CMS-HCC V28 community payment model. F41.1 has a separate mapping under the Part D RxHCC model (HCC 133 (Anxiety and Other Psychiatric Disorders)); the applicable result needs member context. Do not assign V28 risk adjustment value from this page; verify the applicable model and payment year before using this code for risk adjustment.
Ensure documentation specifies the duration of anxiety symptoms (minimum 6 months required).
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for F41.1 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Ensure documentation specifies the duration of anxiety symptoms (minimum 6 months required)
- •Note whether the anxiety is affecting work, social, or personal functioning

- ✓Excessive anxiety and worry about multiple events or activities for at least 6 months
- ✓Difficulty controlling the worry
- ✓At least three associated symptoms: restlessness, fatigue, difficulty concentrating, irritability, muscle tension, sleep disturbance

- ✓Anxiety not better explained by another mental disorder or medical condition
- ✓Current treatment plan including therapy and/or medications

- •F40.10 (Social phobia, unspecified): Social phobia is situation-specific; GAD involves worry across multiple domains
- •F32.1 (Major depressive disorder, single episode, moderate): Depression and GAD frequently co-occur but are distinct diagnoses; both may be coded if both are documented
