Is F60.9 an HCC code?
Yes. F60.9 (Personality disorder, unspecified) maps to HCC 153, Personality Disorders; Anorexia/Bulimia Nervosa under the CMS-HCC V28 risk adjustment model, with a source-labeled community non-dual aged reference coefficient of 0.396. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes. It is billable for payment year 2026.
Coder answer: F60.9 is billable and maps to V28 HCC 153, Personality Disorders; Anorexia/Bulimia Nervosa. Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

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 F60.9
For F60.9, 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
F60.9 is the ICD-10-CM diagnosis code for personality disorder, unspecified. A diagnosis of personality disorder when the specific type has not been determined or documented. F60.9 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering disorders of adult personality and behavior (f60-f69).
Under the CMS-HCC V28 risk adjustment model, F60.9 maps to Personality Disorders; Anorexia/Bulimia Nervosa (HCC 153) with a source-labeled community, non-dual, aged reference coefficient of 0.396. No V24 mapping is shown for F60.9; use the applicable model and payment year when reviewing the V28 mapping. For CY2026 non-PACE Medicare Advantage, CMS uses 100% of the 2024 CMS-HCC model (V28). PACE uses a separate model blend. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes.
This is a non-specific code; attempt to identify the specific personality disorder type for more precise coding. For F60.9, 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. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for F60.9 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This is a non-specific code; attempt to identify the specific personality disorder type for more precise coding
- •Use only when clinical documentation is insufficient to specify which personality disorder is present
Clinical Significance
Unspecified personality disorder is used when the provider documents a personality disorder diagnosis but does not specify the type. While clinically valid in certain contexts, this code provides less specificity for risk adjustment and care planning. It still indicates the patient has a chronic behavioral health condition requiring ongoing management and monitoring.
Documentation Requirements
- ✓Provider documentation explicitly stating a personality disorder diagnosis
- ✓Evidence of enduring maladaptive personality patterns causing functional impairment
- ✓Documentation should ideally specify the type — query the provider if the specific personality disorder can be identified
- ✓Clinical distinction from temporary behavioral disturbances or adjustment disorders
- ✓Treatment plan addressing the personality disorder
Commonly Confused Codes
- •F60.89: Other specific personality disorders; use F60.89 when the provider names a specific type that lacks its own code, reserve F60.9 for truly unspecified cases
- •F69: Unspecified disorder of adult personality and behavior; F69 is even broader and includes behavioral disorders, not just personality disorders
- •F60.3: Borderline personality disorder; if borderline features are documented, query for specificity rather than defaulting to F60.9
- •Z73.1: Type A behavior pattern; personality traits or behavioral patterns are not the same as personality disorders
