Is F13.27 an HCC code?
Yes. F13.27 (Sedative, hypnotic or anxiolytic dependence with sedative, hypnotic or anxiolytic-induced persisting dementia) maps to HCC 135, Drug Use with 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: F13.27 is billable and maps to V28 HCC 135, Drug Use with 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 F13.27
For F13.27, 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
F13.27 is the ICD-10-CM diagnosis code for sedative, hypnotic or anxiolytic dependence with sedative, hypnotic or anxiolytic-induced persisting dementia. A person is dependent on sedatives, sleeping pills, or anti-anxiety medications and has developed progressive cognitive decline and dementia caused by these drugs. F13.27 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, F13.27 maps to Drug Use with Psychotic Complications (HCC 135) with a source-labeled community, non-dual, aged reference coefficient of 0.424. No V24 mapping is shown for F13.27; 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.
Ensure documentation distinguishes substance-induced dementia from primary neurodegenerative dementias. For F13.27, 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 F13.27 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Ensure documentation distinguishes substance-induced dementia from primary neurodegenerative dementias
- •Note the timeline of cognitive decline in relation to substance use initiation
Clinical Significance
Sedative-induced persisting dementia is one of the most severe long-term consequences of sedative dependence, representing irreversible global cognitive decline caused by chronic substance use. Unlike the amnestic disorder, dementia involves multiple cognitive domains including memory, executive function, language, and visuospatial abilities. This diagnosis significantly impacts functional independence and care needs.
Documentation Requirements
- ✓Documentation of sedative, hypnotic, or anxiolytic dependence history
- ✓Neuropsychological testing showing decline in multiple cognitive domains
- ✓Evidence the dementia persists beyond substance cessation
- ✓Temporal relationship between chronic substance use and cognitive decline onset
- ✓Distinction from primary neurodegenerative dementias (Alzheimer disease, vascular dementia)
- ✓Functional assessment documenting impact on activities of daily living and instrumental activities
- ✓Brain imaging results if available (MRI/CT showing atrophy patterns)
Commonly Confused Codes
- •F13.26: Dependence with persisting amnestic disorder; limited to memory impairment only
- •F13.97: Unspecified use with persisting dementia; use when dependence is not confirmed
- •G30.9: Alzheimer disease, unspecified; primary neurodegenerative dementia
- •F01.50: Vascular dementia without behavioral disturbance; different etiology
- •F03.90: Unspecified dementia without behavioral disturbance; does not capture substance etiology
