About coding mild neurocognitive disorder substance-induced
The ICD-10-CM code for mild neurocognitive disorder substance-induced is F19.988 (Other psychoactive substance use, unspecified with other psychoactive substance-induced disorder).
Within F19.98, choose F19.988 (other psychoactive substance-induced disorder) only when documentation doesn't support a more specific option: psychoactive substance-induced anxiety disorder (F19.980), psychoactive substance-induced sexual dysfunction (F19.981) and psychoactive substance-induced sleep disorder (F19.982).
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.
