F15.150
BillableOther stimulant abuse with stimulant-induced psychotic disorder with delusions
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is F15.150 an HCC code?
Yes. F15.150 maps to Drug/Alcohol Psychosis under the CMS-HCC V28 risk adjustment model (and Drug/Alcohol Psychosis 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 F15.150
For F15.150 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 F15.150 during that encounter — not just copy-forwarded from a problem list.
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/Alcohol Psychosis (HCC 135) with a community, non-dual, aged base RAF weight of 0.000. Under the older V24 model, F15.150 mapped to the same category but with a base RAF weight of 0.434 — V28 recalibrated weights across the entire model. 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 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. Because F15.150 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 F15.150 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
