Buddy Documentation Tip

HCC Buddy guidance

Documentation of alcohol dependence with at least three of: tolerance, withdrawal, use in larger amounts/longer periods than intended, persistent desire or unsuccessful efforts to cut down, significant time spent obtaining/using/recovering, important activities given up, continued use despite knowledge of physical/psychological problems

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.)

Assessment and plan addressing alcohol use disorder with treatment recommendations (counseling, medication-assisted treatment, referral, etc.)

Audit Caution

HCC Buddy guidance

Downcoding alcohol dependence to abuse — if the provider documents 'dependence,' code dependence regardless of the current clinical presentation

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

F10.1x — Alcohol abuse codes; abuse is a less severe pattern — if documentation says 'dependence,' do not downcode to abuse

F10.9x — Alcohol use, unspecified; always code dependence when documented, as it carries appropriate risk adjustment weight

Is F10.280 an HCC code?

Yes. F10.280 (Alcohol dependence with alcohol-induced anxiety 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: F10.280 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.

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.

MEAT review for F10.280

For F10.280, 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

F10.280 is the ICD-10-CM diagnosis code for alcohol dependence with alcohol-induced anxiety disorder. A person who is dependent on alcohol and has developed an anxiety disorder caused by their alcohol use. F10.280 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, F10.280 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.

The anxiety must be documented as alcohol-induced; distinguish from anxiety that preceded alcohol dependence. For F10.280, 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 F10.280 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•The anxiety must be documented as alcohol-induced; distinguish from anxiety that preceded alcohol dependence
•Consider whether anxiety symptoms persist during sobriety to confirm alcohol-induced etiology

Clinical Significance

This code captures alcohol dependence 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 alcohol dependence with at least three of: tolerance, withdrawal, use in larger amounts/longer periods than intended, persistent desire or unsuccessful efforts to cut down, significant time spent obtaining/using/recovering, important activities given up, continued use despite knowledge of physical/psychological problems
✓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.)

Commonly Confused Codes

•F10.1x: Alcohol abuse codes; abuse is a less severe pattern: if documentation says 'dependence,' do not downcode to abuse
•F10.9x: Alcohol use, unspecified; always code dependence when documented, as it carries appropriate risk adjustment weight
