Is F15.150 an HCC code?
Yes. F15.150 (Other stimulant abuse with stimulant-induced psychotic disorder with delusions) 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: F15.150 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 F15.150
For F15.150, 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
F15.150 is the ICD-10-CM diagnosis code for other stimulant abuse with stimulant-induced psychotic disorder with delusions. This code describes a situation where someone is abusing stimulant drugs (like cocaine or amphetamines) and is experiencing psychotic symptoms, specifically delusions (false beliefs). The psychotic symptoms are directly caused by the stimulant abuse. F15.150 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, F15.150 maps to Drug Use with Psychotic Complications (HCC 135) with a source-labeled community, non-dual, aged reference coefficient of 0.424. 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 clearly states both the stimulant abuse AND the psychotic disorder with delusions to justify this specific code; do not use if psychotic symptoms existed before stimulant use began. For F15.150, 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 F15.150 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify documentation clearly states both the stimulant abuse AND the psychotic disorder with delusions to justify this specific code; do not use if psychotic symptoms existed before stimulant use began
- •The fifth character '0' indicates this is the initial encounter; use '1' for early remission, '2' for sustained remission, or '3' for in controlled environment as appropriate based on clinical documentation
Clinical Significance
Stimulant-induced psychotic disorder with delusions in the context of stimulant abuse represents a serious psychiatric complication that significantly increases morbidity and healthcare utilization. This diagnosis indicates the patient has crossed from substance abuse into substance-induced psychosis, requiring intensive psychiatric management and often inpatient stabilization. Accurate capture is essential for risk adjustment as it reflects higher expected costs compared to uncomplicated substance abuse.
Documentation Requirements
- ✓Documented pattern of stimulant abuse (not dependence) with specific stimulant identified when possible
- ✓Clinical description of psychotic symptoms specifically characterized as delusions (fixed false beliefs)
- ✓Temporal relationship establishing that psychotic symptoms developed during or shortly after stimulant use
- ✓Documentation that delusions are not better explained by a primary psychotic disorder (e.g., schizophrenia)
- ✓Current clinical status: active, early remission, sustained remission, or in controlled environment
Commonly Confused Codes
- •F15.151: Stimulant abuse with psychotic disorder with hallucinations; use F15.150 specifically when delusions (not hallucinations) are the predominant psychotic feature
- •F15.250: Stimulant dependence with psychotic disorder with delusions; distinction is abuse vs. dependence severity
- •F15.159: Stimulant abuse with psychotic disorder, unspecified; use F15.150 when delusions are specifically documented
- •F25.0: Schizoaffective disorder, bipolar type; this is a primary psychotic disorder, not substance-induced
- •F14.150: Cocaine abuse with cocaine-induced psychotic disorder with delusions; use when cocaine is specifically identified
