What This Code Means

A person dependent on hallucinogenic drugs is experiencing psychosis (loss of touch with reality) caused by the hallucinogen use, but the specific features are not detailed.

Coding Tips

  • Use this code when hallucinogen-induced psychotic disorder is documented but hallucinations are not specifically mentioned
  • Query the provider to determine if hallucinations are present to potentially use the more specific F16.251

Clinical Significance

This unspecified psychotic disorder code captures hallucinogen-induced psychosis when the documentation does not clarify whether delusions or hallucinations predominate. It still maps to the higher-weighted psychosis HCC but represents a documentation improvement opportunity.

Documentation Requirements

  • Documentation of hallucinogen dependence
  • Evidence of psychotic symptoms linked to hallucinogen use
  • Provider query for specific psychotic features (delusions vs hallucinations)
  • Mental status examination supporting psychotic disorder diagnosis
  • Treatment plan addressing psychotic symptoms
