F60.1
BillableSchizoid personality disorder
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is F60.1 an HCC code?
Yes. F60.1 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 F60.1
For F60.1 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 F60.1 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
F60.1 is the ICD-10-CM diagnosis code for schizoid personality disorder. A personality pattern marked by emotional detachment, limited interest in relationships, and preference for solitary activities. F60.1 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, F60.1 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, F60.1 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.
Verify that the patient demonstrates pervasive indifference to social relationships across multiple contexts. Because F60.1 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 F60.1 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify that the patient demonstrates pervasive indifference to social relationships across multiple contexts
- •Differentiate from autism spectrum disorder and social anxiety disorder, which have different diagnostic criteria
Clinical Significance
Schizoid personality disorder is characterized by a pervasive pattern of detachment from social relationships and a restricted range of emotional expression. These patients appear cold, aloof, and uninterested in close relationships. This condition impacts healthcare by reducing patient engagement, limiting therapeutic alliances, and decreasing follow-up adherence.
Documentation Requirements
- ✓Documentation of pervasive detachment from social relationships and restricted emotional expression beginning by early adulthood
- ✓Evidence of at least four DSM-5 criteria (neither desires nor enjoys close relationships, chooses solitary activities, little interest in sexual experiences, takes pleasure in few activities, lacks close friends, indifferent to praise/criticism, emotional coldness/detachment)
- ✓Pattern is enduring, inflexible, and pervasive
- ✓Does not occur exclusively during schizophrenia, bipolar, depressive disorder with psychotic features, or autism spectrum disorder
- ✓Differentiation from social anxiety or autism spectrum disorder
