Buddy Documentation Tip

HCC Buddy guidance

Documentation of a maladaptive pattern of alcohol use with clinically significant impairment or distress (recurrent use causing role failure, hazardous use, legal problems, or social/interpersonal problems)

Confirmation that criteria for alcohol dependence are NOT met (no tolerance, withdrawal, or compulsive use pattern)

Documentation that the psychotic disorder with hallucinations is directly attributable to alcohol use, not a primary/independent psychiatric disorder

Documentation of psychotic symptoms (delusions and/or hallucinations) and their temporal relationship to alcohol use

MEAT Support

HCC Buddy guidance

Confirmation that criteria for alcohol dependence are NOT met (no tolerance, withdrawal, or compulsive use pattern)

Documentation that the psychotic disorder with hallucinations is directly attributable to alcohol use, not a primary/independent psychiatric disorder

Documentation of psychotic symptoms (delusions and/or hallucinations) and their temporal relationship to alcohol use

Audit Caution

HCC Buddy guidance

Coding alcohol abuse when documentation actually supports dependence (tolerance, withdrawal, compulsive use) — always use the highest severity level documented

Assigning an alcohol use disorder code based solely on lab values (elevated GGT, MCV) without provider documentation of the clinical diagnosis

Coding a primary psychiatric disorder separately when the condition is substance-induced — the combination code captures both the substance use and the psychiatric manifestation

Failing to establish the temporal relationship between alcohol use and psychiatric symptoms — substance-induced conditions onset during or shortly after intoxication/withdrawal

Common Mistakes

HCC Buddy guidance

F10.2x — Alcohol dependence codes; dependence is a more severe pattern with tolerance/withdrawal/compulsive use — verify provider intent

F10.9x — Alcohol use, unspecified; less specific — always code to the highest documented specificity (abuse > unspecified)

F20.x — Schizophrenia spectrum disorders; primary psychotic disorders are independent of substance use — verify temporal relationship to alcohol

Is F10.151 an HCC code?

Yes. F10.151 (Alcohol abuse 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: F10.151 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.

Not separately weighted

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.

What This Code Means

F10.151 is the ICD-10-CM diagnosis code for alcohol abuse with alcohol-induced psychotic disorder with hallucinations. A person who abuses alcohol and experiences hallucinations (seeing or hearing things that aren't there) as a direct result of their alcohol use. F10.151 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, F10.151 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 F10.151; 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.

Document the presence of hallucinations specifically in the clinical record to support this more specific code versus F10.159. For F10.151, 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 F10.151 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Document the presence of hallucinations specifically in the clinical record to support this more specific code versus F10.159
•Ensure documentation clearly links the psychotic symptoms to alcohol abuse rather than an independent psychiatric condition

Clinical Significance

This code captures alcohol abuse with alcohol-induced psychotic disorder with hallucinations, documenting a psychiatric manifestation directly caused by alcohol use. The distinction between substance-induced psychiatric symptoms and primary psychiatric disorders is clinically crucial for treatment planning — substance-induced conditions may resolve with sustained sobriety. These combination codes carry higher risk adjustment weight reflecting the dual complexity of substance use disorder combined with psychiatric comorbidity.

Documentation Requirements

✓Documentation of a maladaptive pattern of alcohol use with clinically significant impairment or distress (recurrent use causing role failure, hazardous use, legal problems, or social/interpersonal problems)
✓Confirmation that criteria for alcohol dependence are NOT met (no tolerance, withdrawal, or compulsive use pattern)
✓Documentation that the psychotic disorder with hallucinations is directly attributable to alcohol use, not a primary/independent psychiatric disorder
✓Documentation of psychotic symptoms (delusions and/or hallucinations) and their temporal relationship to alcohol use
✓Assessment and plan addressing alcohol use disorder with treatment recommendations (counseling, medication-assisted treatment, referral, etc.)

Commonly Confused Codes

•F10.2x: Alcohol dependence codes; dependence is a more severe pattern with tolerance/withdrawal/compulsive use: verify provider intent
•F10.9x: Alcohol use, unspecified; less specific: always code to the highest documented specificity (abuse > unspecified)
•F20.x: Schizophrenia spectrum disorders; primary psychotic disorders are independent of substance use: verify temporal relationship to alcohol
