F60.9
BillablePersonality disorder, unspecified
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is F60.9 an HCC code?
Yes. F60.9 maps to Personality Disorders and Dissociative Disorders under the CMS-HCC V28 risk adjustment model (and Personality Disorders under V24).
HCC Category Mapping
RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.
MEAT Criteria for F60.9
For F60.9 to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically — it has to be re-documented and supported each calendar year.
- 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
Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed F60.9 during that encounter — not just copy-forwarded from a problem list.
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 and Dissociative Disorders (HCC 153) with a community, non-dual, aged base RAF weight of 1.241. Under the older CMS-HCC V24 model, F60.9 maps to Personality Disorders (HCC 60) with a community, non-dual, aged base RAF weight of 0.000. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.
This is a non-specific code; attempt to identify the specific personality disorder type for more precise coding. Because F60.9 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. 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, RAF weights, 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
