Is F19.982 an HCC code?
Yes. F19.982 (Other psychoactive substance use, unspecified with psychoactive substance-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: F19.982 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 F19.982
For F19.982, 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
F19.982 is the ICD-10-CM diagnosis code for other psychoactive substance use, unspecified with psychoactive substance-induced sleep disorder. Sleep problems such as insomnia, excessive sleepiness, or abnormal sleep patterns that develop directly from the use of various psychoactive substances. F19.982 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, F19.982 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 F19.982; 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.
Specify the type of sleep disturbance (insomnia, hypersomnia, parasomnia) when documented. For F19.982, 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 F19.982 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Specify the type of sleep disturbance (insomnia, hypersomnia, parasomnia) when documented
- •Note whether sleep problems occur during use, withdrawal, or both
Clinical Significance
Other psychoactive substance use, unspecified with substance-induced sleep disorder captures sleep disturbances (insomnia, hypersomnia, parasomnias) directly caused by substance use. Sleep disorders are among the most prevalent comorbidities in substance users and significantly impact treatment outcomes and relapse risk. Accurate coding of this dual condition supports risk adjustment and reflects the integrated care approach needed for these patients.
Documentation Requirements
- ✓Documentation of current psychoactive substance use
- ✓Specific type of sleep disorder identified (insomnia, hypersomnia, parasomnia, circadian rhythm disruption)
- ✓Temporal relationship between substance use and sleep disorder onset
- ✓Provider determination that sleep disturbance is substance-induced
- ✓Assessment of sleep disorder severity and impact on daily functioning
- ✓Whether sleep problems occur during active use, withdrawal, or both
Commonly Confused Codes
- •F19.282: Substance DEPENDENCE with induced sleep disorder; use when dependence criteria are documented
- •F19.182: Substance ABUSE with induced sleep disorder; use when abuse criteria are documented
- •G47.00: Insomnia, unspecified is a primary diagnosis not attributed to substance use
- •F51.01: Primary insomnia should be used when sleep disorder is unrelated to substance use
- •G47.10: Hypersomnia, unspecified should be used for primary hypersomnia
