HCC Category Mapping

What This Code Means

Misuse of hallucinogenic drugs leading to a persistent psychotic disorder with unspecified psychotic features.

Coding Tips

• •Use this code when hallucinogen-induced psychotic disorder is documented but the specific psychotic features are not detailed
• •Attempt to obtain clarification on whether delusions, hallucinations, or other psychotic symptoms are present

Clinical Significance

Hallucinogen abuse with unspecified psychotic disorder indicates psychotic features from hallucinogen abuse that are not further characterized as delusions or hallucinations. While still mapping to the highest substance use HCC, this code represents a documentation gap. Provider queries should be initiated to specify the psychotic manifestation for stronger clinical documentation and audit defensibility.

Documentation Requirements

• ✓Documented hallucinogen abuse
• ✓Evidence of psychotic symptoms attributed to hallucinogen use
• ✓Query to provider to specify delusions vs. hallucinations
• ✓Documentation that psychosis is substance-induced and persists beyond expected intoxication effects
• ✓Psychiatric evaluation and treatment plan
