F10.988
BillableAlcohol use, unspecified with other alcohol-induced disorder
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is F10.988 an HCC code?
Yes. F10.988 maps to Alcohol Use Disorder under the CMS-HCC V28 risk adjustment model (and Drug/Alcohol Dependence 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 F10.988
For F10.988 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 F10.988 during that encounter — not just copy-forwarded from a problem list.
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 (HCC 139) with a community, non-dual, aged base RAF weight of 0.584. Under the older CMS-HCC V24 model, F10.988 maps to Drug/Alcohol Dependence (HCC 55) with a community, non-dual, aged base RAF weight of 0.334. 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.
Use this code only when a more specific F10.98x code does not apply; document the specific disorder in the medical record. Because F10.988 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 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
