F10.180
BillableAlcohol abuse with alcohol-induced anxiety disorder
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is F10.180 an HCC code?
Yes. F10.180 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 F10.180
For F10.180 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 F10.180 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
F10.180 is the ICD-10-CM diagnosis code for alcohol abuse with alcohol-induced anxiety disorder. A person who abuses alcohol and develops anxiety symptoms (such as worry, nervousness, or panic) caused by their alcohol use. F10.180 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, F10.180 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, F10.180 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.
Distinguish between alcohol-induced anxiety and pre-existing anxiety disorder by reviewing the timeline of symptom onset. Because F10.180 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 F10.180 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Distinguish between alcohol-induced anxiety and pre-existing anxiety disorder by reviewing the timeline of symptom onset
- •Document that anxiety symptoms are directly related to alcohol abuse rather than a separate anxiety disorder
Clinical Significance
This code captures alcohol abuse with alcohol-induced anxiety disorder, 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 anxiety disorder is directly attributable to alcohol use, not a primary/independent psychiatric disorder
- ✓Assessment and plan addressing alcohol use disorder with treatment recommendations (counseling, medication-assisted treatment, referral, etc.)
