What is ICD-10 code F14.159?

F14.159 is the ICD-10-CM diagnosis code for Cocaine abuse with cocaine-induced psychotic disorder, unspecified. A person who abuses cocaine and experiences psychotic symptoms, but the specific type of psychotic symptom is not clearly documented. It belongs to the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99). F14.159 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. F14.159 is part of the FY2026 ICD-10-CM code set published by the CMS National Center for Health Statistics and used on Medicare, Medicaid, and commercial claims in the United States.

Yes. F14.159 is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. F14.159 is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

Which HCC does F14.159 map to under V28?

F14.159 maps to CMS-HCC V28 HCC 135 (Drug Use with Psychotic Complications). The category numbers, labels, and conditions come from the CMS-HCC V28 model file for payment year 2026.

Using this unspecified code when documentation actually supports a more specific psychosis subtype

Not querying the provider to clarify whether delusions or hallucinations are present

Confusing this psychotic disorder code with intoxication-related perceptual disturbance codes

Failing to differentiate abuse from dependence status

Common Mistakes

HCC Buddy guidance

F14.150 — Cocaine abuse with cocaine-induced psychotic disorder with delusions: preferred when delusions are specifically documented

F14.151 — Cocaine abuse with cocaine-induced psychotic disorder with hallucinations: preferred when hallucinations are specifically documented

F14.122 — Cocaine abuse with intoxication with perceptual disturbance: lower-acuity code for perceptual changes not meeting psychosis criteria

F14.259 — Cocaine dependence with cocaine-induced psychotic disorder, unspecified: use when pattern is dependence

Is F14.159 an HCC code?

Yes. F14.159 (Cocaine abuse with cocaine-induced psychotic disorder, unspecified) 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: F14.159 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.

Not separately weighted

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 F14.159

For F14.159, 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

F14.159 is the ICD-10-CM diagnosis code for cocaine abuse with cocaine-induced psychotic disorder, unspecified. A person who abuses cocaine and experiences psychotic symptoms, but the specific type of psychotic symptom is not clearly documented. F14.159 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, F14.159 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 F14.159; 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.

Use this code only when psychotic disorder is documented but neither delusions nor hallucinations are specifically identified. For F14.159, 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 F14.159 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Use this code only when psychotic disorder is documented but neither delusions nor hallucinations are specifically identified
•Query the provider if possible to determine the specific psychotic manifestation for more precise coding

Clinical Significance

This code captures cocaine abuse with cocaine-induced psychotic disorder where the specific type of psychotic symptom (delusions vs. hallucinations) is not documented. While it reflects a serious psychiatric complication of cocaine use, the unspecified nature indicates a documentation gap. Cocaine-induced psychosis is a high-acuity condition regardless of specification, and carries significant risk for violent behavior, self-harm, and need for inpatient psychiatric care.

Documentation Requirements

✓Provider documentation of cocaine abuse pattern
✓Statement that psychotic symptoms are cocaine-induced
✓Documentation of psychotic symptoms present (even if not specified as delusions or hallucinations)
✓Exclusion of primary psychotic disorders as the etiology
✓Temporal relationship between cocaine use and psychotic symptom onset
✓Mental status examination supporting the presence of psychosis
