About coding anxiety disorder phencyclidine-induced

The ICD-10-CM code for anxiety disorder phencyclidine-induced is F16.980 (Hallucinogen use, unspecified with hallucinogen-induced anxiety disorder).

Within F16.98 (hallucinogen use, unspecified with other specified hallucinogen-induced disorder), F16.980 is specifically for hallucinogen use, unspecified with hallucinogen-induced anxiety disorder. Related codes cover hallucinogen persisting perception disorder (flashbacks) (F16.983) and other hallucinogen-induced disorder (F16.988).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 894 (Alcohol, Drug Abuse or Dependence, Left AMA, relative weight 0.6275), DRG 895 (Alcohol, Drug Abuse or Dependence with Rehabilitation Therapy, relative weight 1.4266), DRG 896 (Alcohol, Drug Abuse or Dependence without Rehabilitation Therapy with MCC, relative weight 1.6617) and DRG 897 (Alcohol, Drug Abuse or Dependence without Rehabilitation Therapy without MCC, relative weight 0.8584), in MDC 20 (Alcohol/Drug Use and Alcohol/Drug Induced Organic Mental Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
