Coding Tips

Documentation Requirements
- ✓Documentation of hallucinogen use with intoxication
- ✓Provider query for both use pattern (abuse vs dependence) and intoxication details (delirium present or absent)
- ✓Clinical signs of intoxication noted in the record
- ✓Reason specificity cannot be achieved
- ✓Follow-up plan for substance use disorder evaluation
