About F13.91

F13.91 is the ICD-10-CM diagnosis code for sedative, hypnotic or anxiolytic use, unspecified, in remission. It belongs to category F13 (sedative, hypnotic, or anxiolytic related disorders), block F10-F19 (mental and behavioral disorders due to psychoactive substance use) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within F13.9, choose F13.91 (hypnotic or anxiolytic use, unspecified, in remission) only when documentation doesn't support a more specific option: hypnotic, or anxiolytic use, unspecified, uncomplicated (F13.90), hypnotic or anxiolytic use, unspecified with intoxication (F13.92), hypnotic or anxiolytic use, unspecified with withdrawal (F13.93), hypnotic or anxiolytic use, unspecified with sedative, hypnotic or anxiolytic-induced mood disorder (F13.94), hypnotic or anxiolytic use, unspecified with sedative, hypnotic or anxiolytic-induced psychotic disorder (F13.95), hypnotic or anxiolytic use, unspecified with sedative, hypnotic or anxiolytic-induced persisting amnestic disorder (F13.96), hypnotic or anxiolytic use, unspecified with sedative, hypnotic or anxiolytic-induced persisting dementia (F13.97), hypnotic or anxiolytic use, unspecified with other sedative, hypnotic or anxiolytic-induced disorders (F13.98) and 1 more.

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.

It was added in FY2023, effective October 1, 2022.
