Provider documentation of history of stimulant abuse (not dependence)
Clear statement that the patient is in remission
Specification of remission type (early vs. sustained) when available
Documentation of the specific stimulant previously abused when possible

Audit Caution

HCC Buddy guidance
Using this code when the patient is still actively abusing stimulants
Coding remission of abuse when the prior pattern was actually dependence (requires F15.21)
Using cocaine abuse in remission codes (F14.11) for non-cocaine stimulants
Dropping the code entirely because the patient is in remission — remission codes still capture important clinical history

Common Mistakes

HCC Buddy guidance
F15.10 — Other stimulant abuse, uncomplicated: use when the patient still meets active abuse criteria
F15.21 — Other stimulant dependence, in remission: use when the prior pattern was dependence, not abuse
F14.11 — Cocaine abuse, in remission: use for cocaine-specific abuse in remission
Z87.898 — Personal history of other specified risk factors: sometimes incorrectly used instead of remission codes

Is F15.11 an HCC code?

Yes. F15.11 (Other stimulant abuse, in remission) maps to HCC 138, Drug Use Disorder, Mild, Uncomplicated, Except Cannabis under the CMS-HCC V28 risk adjustment model, with a source-labeled community non-dual aged reference coefficient of 0.423. 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: F15.11 is billable and maps to V28 HCC 138, Drug Use Disorder, Mild, Uncomplicated, Except Cannabis. 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 F15.11

For F15.11, 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

F15.11 is the ICD-10-CM diagnosis code for other stimulant abuse, in remission. A person who previously abused stimulant drugs other than cocaine but is now in recovery or remission from that abuse. F15.11 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, F15.11 maps to Drug Use Disorder, Mild, Uncomplicated, Except Cannabis (HCC 138) with a source-labeled community, non-dual, aged reference coefficient of 0.423. No V24 mapping is shown for F15.11; 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 this code when the patient is no longer actively abusing the substance but has a history of abuse. For F15.11, 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 F15.11 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • •Use this code when the patient is no longer actively abusing the substance but has a history of abuse
  • •Document the length of remission if available (early vs sustained remission)

Clinical Significance

Other stimulant abuse, in remission indicates a patient with a history of stimulant abuse (other than cocaine) who is no longer meeting active criteria for the disorder. This code is important for ongoing monitoring because stimulant abuse has high relapse rates, and patients in remission require continued surveillance for relapse triggers, long-term health consequences (cardiovascular disease, dental problems from methamphetamine, cognitive impairment), and psychiatric comorbidities.

Documentation Requirements

  • ✓Provider documentation of history of stimulant abuse (not dependence)
  • ✓Clear statement that the patient is in remission
  • ✓Specification of remission type (early vs. sustained) when available
  • ✓Documentation of the specific stimulant previously abused when possible
  • ✓Current recovery status and ongoing treatment or support
  • ✓Assessment of relapse risk factors

Commonly Confused Codes

  • •F15.10: Other stimulant abuse, uncomplicated: use when the patient still meets active abuse criteria
  • •F15.21: Other stimulant dependence, in remission: use when the prior pattern was dependence, not abuse
  • •F14.11: Cocaine abuse, in remission: use for cocaine-specific abuse in remission
  • •Z87.898: Personal history of other specified risk factors: sometimes incorrectly used instead of remission codes
  • •F15.90: Other stimulant use, unspecified, uncomplicated: use when abuse vs. dependence is unclear
