ICD-10 code for methadone maintenance

The ICD-10-CM code for methadone maintenance is F11.20 (Opioid dependence, uncomplicated).

Within F11.2 (opioid dependence), F11.20 is specifically for opioid dependence, uncomplicated. Related codes cover in remission (F11.21), with intoxication (F11.22), with withdrawal (F11.23), with opioid-induced mood disorder (F11.24), with opioid-induced psychotic disorder (F11.25), with other opioid-induced disorder (F11.28) and with unspecified opioid-induced disorder (F11.29).

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.
