Audit Caution

HCC Buddy guidance
Defaulting to this code without reviewing the full clinical documentation for specific intoxication details
Not querying the provider when the intoxication presentation is described but not explicitly categorized
Using this code when the record clearly describes delirium or perceptual disturbances
Confusing intoxication with withdrawal presentations

Common Mistakes

HCC Buddy guidance
F15.220 — Use when intoxication is specifically documented as uncomplicated
F15.221 — Use when delirium is present during intoxication
F15.222 — Use when perceptual disturbances are present during intoxication
F15.929 — Stimulant use, unspecified with intoxication, unspecified; double unspecified, even less precise

Is F15.229 an HCC code?

Yes. F15.229 (Other stimulant dependence with intoxication, unspecified) maps to HCC 137, Drug Use Disorder, Moderate/Severe, or Drug Use with Non-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: F15.229 is billable and maps to V28 HCC 137, Drug Use Disorder, Moderate/Severe, or Drug Use with Non-Psychotic Complications. Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

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 F15.229

For F15.229, 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

F15.229 is the ICD-10-CM diagnosis code for other stimulant dependence with intoxication, unspecified. A person dependent on stimulants who is intoxicated, but the specific type of intoxication complication is not specified or documented. F15.229 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, F15.229 maps to Drug Use Disorder, Moderate/Severe, or Drug Use with Non-Psychotic Complications (HCC 137) with a source-labeled community, non-dual, aged reference coefficient of 0.424. No V24 mapping is shown for F15.229; 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.

Use only when intoxication is documented but details about delirium or perceptual disturbances are unclear. For F15.229, 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 F15.229 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • •Use only when intoxication is documented but details about delirium or perceptual disturbances are unclear
  • •Query provider for clarification on intoxication symptoms when possible to assign more specific code

Clinical Significance

Stimulant dependence with unspecified intoxication is used when a dependent patient is documented as intoxicated but the specific manifestation (uncomplicated, delirium, or perceptual disturbance) is not described. While this captures the clinical situation, it represents a documentation gap that may weaken audit defensibility. Querying the provider for more specific intoxication details is recommended.

Documentation Requirements

  • ✓Documented stimulant dependence
  • ✓Evidence of current intoxication
  • ✓Query sent to provider for specification of intoxication complications if not documented
  • ✓Clinical signs of stimulant intoxication noted in the record
  • ✓Any treatment provided for the intoxication episode

Commonly Confused Codes

  • •F15.220: Use when intoxication is specifically documented as uncomplicated
  • •F15.221: Use when delirium is present during intoxication
  • •F15.222: Use when perceptual disturbances are present during intoxication
  • •F15.929: Stimulant use, unspecified with intoxication, unspecified; double unspecified, even less precise

F15.229 maps to CMS-HCC V28 category 137, Drug Use Disorder, Moderate/Severe, or Drug Use with Non-Psychotic Complications. See the ICD-10 to HCC mapping hub for how the V28 crosswalk works. The mapping identifies a payment HCC category for F15.229. Review its source-labeled HCC coefficient above, check the RAF Calculator with complete member context for CMS-HCC V28 PY2026, and confirm the documentation the chart needs before the code is submitted. HCC Buddy shows no RAF score unless every required source and calculation check passes.
