Is F15.982 an HCC code?
Yes. F15.982 (Other stimulant use, unspecified with stimulant-induced sleep disorder) 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: F15.982 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.

HCC Category Mapping
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 F15.982
For F15.982, 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
F15.982 is the ICD-10-CM diagnosis code for other stimulant use, unspecified with stimulant-induced sleep disorder. This code describes sleep problems caused by the use of stimulant drugs (such as cocaine, amphetamines, or other similar substances) when the specific type of stimulant or pattern of use is not documented. The person is experiencing difficulty sleeping as a direct result of stimulant substance use. F15.982 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, F15.982 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 F15.982; 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.
Verify documentation specifies stimulant-induced sleep disorder; if a specific stimulant is identified (cocaine, amphetamines, etc.), use the more specific F15.x code for that substance instead. For F15.982, 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 F15.982 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify documentation specifies stimulant-induced sleep disorder; if a specific stimulant is identified (cocaine, amphetamines, etc.), use the more specific F15.x code for that substance instead
- •This code requires documentation linking the sleep disturbance directly to stimulant use; ensure the clinical record supports this causal relationship before assigning
Clinical Significance
Stimulant use, unspecified with stimulant-induced sleep disorder captures sleep disturbances caused by stimulant use when the use pattern is not characterized. Sleep disruption is one of the most predictable complications of stimulant use and significantly impacts overall health, functioning, and recovery. Documenting this complication supports comprehensive care and accurate risk adjustment.
Documentation Requirements
- ✓Documentation of stimulant use
- ✓Specific sleep disorder identified (insomnia, hypersomnia, circadian disruption)
- ✓Causal relationship between stimulant use and sleep disturbance
- ✓Impact on functioning and any treatment interventions
- ✓Query to provider regarding abuse vs. dependence status
