ICD-10 code for addiction

The ICD-10-CM code for addiction is F19.20 (Other psychoactive substance dependence, uncomplicated). The official index lists 8 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F19.20.

Within F19.2 (other psychoactive substance dependence), F19.20 is specifically for other psychoactive substance dependence, uncomplicated. Related codes cover in remission (F19.21), with intoxication (F19.22), with withdrawal (F19.23), with psychoactive substance-induced mood disorder (F19.24), with psychoactive substance-induced psychotic disorder (F19.25), with psychoactive substance-induced persisting amnestic disorder (F19.26), with psychoactive substance-induced persisting dementia (F19.27), with other psychoactive substance-induced disorders (F19.28) and 1 more.

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

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.
