Is F10.988 an HCC code?
Yes. F10.988 (Alcohol use, unspecified with other alcohol-induced disorder) maps to HCC 139, Alcohol Use Disorder, Moderate/Severe, or Alcohol Use with Specified Non-Psychotic Complications under the CMS-HCC V28 risk adjustment model, with a source-labeled community non-dual aged reference coefficient of 0.242. 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: F10.988 is billable and maps to V28 HCC 139, Alcohol Use Disorder, Moderate/Severe, or Alcohol Use with Specified Non-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 F10.988
For F10.988, 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
F10.988 is the ICD-10-CM diagnosis code for alcohol use, unspecified with other alcohol-induced disorder. Other mental or behavioral problems caused by alcohol use that do not fit into the more specific alcohol-related disorder categories. F10.988 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, F10.988 maps to Alcohol Use Disorder, Moderate/Severe, or Alcohol Use with Specified Non-Psychotic Complications (HCC 139) with a source-labeled community, non-dual, aged reference coefficient of 0.242. 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.
Use this code only when a more specific F10.98x code does not apply; document the specific disorder in the medical record. For F10.988, 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 F10.988 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code only when a more specific F10.98x code does not apply; document the specific disorder in the medical record
- •Consider whether additional codes are needed to fully capture all alcohol-induced conditions present
Clinical Significance
This code captures other alcohol-induced disorders that do not fit into the specific categories like mood disorder, anxiety, sleep, or sexual dysfunction. Examples include alcohol-induced movement disorders or other neurological complications. It serves as a catch-all for documented alcohol-induced conditions not elsewhere classified.
Documentation Requirements
- ✓Provider documentation of a specific alcohol-induced disorder not classified under other F10.98x codes
- ✓Clear statement linking the disorder to alcohol use
- ✓Description of the specific disorder or symptoms present
- ✓Alcohol use history and pattern
- ✓Assessment ruling out other etiologies for the condition
Commonly Confused Codes
- •F10.980: Alcohol use, unspecified with alcohol-induced anxiety disorder: use when anxiety is the specific induced disorder
- •F10.981: Alcohol use, unspecified with alcohol-induced sexual dysfunction: use when sexual dysfunction is present
- •F10.982: Alcohol use, unspecified with alcohol-induced sleep disorder: use when sleep disturbance is the issue
- •F10.99: Alcohol use, unspecified with unspecified alcohol-induced disorder: use when the induced disorder itself is not documented
