F14.959
BillableCocaine use, unspecified with cocaine-induced psychotic disorder, unspecified
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is F14.959 an HCC code?
Yes. F14.959 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 F14.959
For F14.959 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 F14.959 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
F14.959 is the ICD-10-CM diagnosis code for cocaine use, unspecified with cocaine-induced psychotic disorder, unspecified. A person using cocaine who develops psychotic symptoms such as hallucinations or delusions, but the specific type of psychotic disorder is not specified. F14.959 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, F14.959 maps to Drug/Alcohol Psychosis (HCC 135) with a community, non-dual, aged base RAF weight of 0.000. Under the older V24 model, F14.959 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.
Use this code when cocaine use is documented but the severity level (mild, moderate, severe) is unclear. Because F14.959 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 F14.959 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code when cocaine use is documented but the severity level (mild, moderate, severe) is unclear
- •If the specific psychotic disorder type is documented (e.g., paranoid), consider using a more specific code if available
Clinical Significance
Cocaine use, unspecified with cocaine-induced psychotic disorder, unspecified is the least specific cocaine psychosis code, with both the use pattern and psychosis type unspecified. Despite this, it still reflects a serious psychiatric complication of cocaine use requiring acute intervention. The lack of specificity represents two documentation gaps: the use pattern (abuse vs. dependence) and the psychotic symptom type (delusions vs. hallucinations). Both should be clarified through provider query.
Documentation Requirements
- ✓Documentation of cocaine use
- ✓Statement that psychotic symptoms are cocaine-induced
- ✓Documentation that psychotic features are present (even without specifying type)
- ✓Exclusion of primary psychotic disorders
- ✓Temporal relationship between cocaine use and psychosis onset
- ✓Mental status examination
- ✓Safety assessment
Commonly Confused Codes
- •F14.950 — Cocaine use, unspecified with cocaine-induced psychotic disorder with delusions: preferred when delusions are documented
- •F14.951 — Cocaine use, unspecified with cocaine-induced psychotic disorder with hallucinations: preferred when hallucinations are documented
- •F14.159 — Cocaine abuse with cocaine-induced psychotic disorder, unspecified: use when abuse is established
- •F14.259 — Cocaine dependence with cocaine-induced psychotic disorder, unspecified: use when dependence is established
- •F14.922 — Cocaine use, unspecified with intoxication with perceptual disturbance: use for transient perceptual changes
