F15.982
BillableOther stimulant use, unspecified with stimulant-induced sleep disorder
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is F15.982 an HCC code?
Yes. F15.982 maps to Drug Use Disorder/Substance Use Disorder, Moderate/Severe 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 F15.982
For F15.982 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 F15.982 during that encounter — not just copy-forwarded from a problem list.
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/Substance Use Disorder, Moderate/Severe (HCC 137) with a community, non-dual, aged base RAF weight of 0.358. Under the older CMS-HCC V24 model, F15.982 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.
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. Because F15.982 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 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
