Is F10.951 an HCC code?
Yes. F10.951 (Alcohol use, unspecified with alcohol-induced psychotic disorder with hallucinations) maps to HCC 136, Alcohol Use with Psychotic Complications under the CMS-HCC V28 risk adjustment model, with a source-labeled community non-dual aged reference coefficient of 0.424. 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: F10.951 is billable and maps to V28 HCC 136, Alcohol Use with Psychotic Complications. 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 F10.951
For F10.951, 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
F10.951 is the ICD-10-CM diagnosis code for alcohol use, unspecified with alcohol-induced psychotic disorder with hallucinations. A serious mental condition where alcohol use causes psychotic symptoms, specifically seeing, hearing, or sensing things that are not actually present. F10.951 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering mental and behavioral disorders due to psychoactive substance use (f10-f19).
Under the CMS-HCC V28 risk adjustment model, F10.951 maps to Alcohol Use with Psychotic Complications (HCC 136) with a source-labeled community, non-dual, aged reference coefficient of 0.424. No V24 mapping is shown for F10.951; 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.
Clearly document the type of hallucinations (auditory, visual, tactile, etc.) in the medical record. For F10.951, 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 F10.951 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Clearly document the type of hallucinations (auditory, visual, tactile, etc.) in the medical record
- •Confirm the hallucinations are directly attributable to alcohol use and not another underlying psychiatric condition
Clinical Significance
Alcohol-induced psychotic disorder with hallucinations indicates alcohol use is causing false sensory perceptions, most commonly visual or auditory hallucinations. This is a serious complication that may occur during active intoxication or withdrawal and requires immediate clinical attention. It reflects high disease burden and resource utilization for risk adjustment purposes.
Documentation Requirements
- ✓Type of hallucinations documented (visual, auditory, tactile, olfactory)
- ✓Temporal relationship between alcohol use/withdrawal and hallucination onset
- ✓Provider statement that hallucinations are alcohol-induced, not from a primary psychiatric disorder
- ✓Mental status examination documenting psychotic features
- ✓Alcohol use history (frequency, quantity, duration)
- ✓Treatment and safety plan
Commonly Confused Codes
- •F10.950: Alcohol use, unspecified with psychotic disorder with delusions: use when false beliefs, not false perceptions, are present
- •F10.931: Alcohol use, unspecified with withdrawal delirium: use when hallucinations occur as part of delirium tremens during withdrawal
- •F10.251: Alcohol dependence with psychotic disorder with hallucinations: use when dependence is documented
- •F20.9: Schizophrenia, unspecified: use only when psychosis is NOT alcohol-induced
