About coding hyperactive
The ICD-10-CM code for hyperactive is F90.9 (Attention-deficit hyperactivity disorder, unspecified type). The official index lists 7 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F90.9.
Within F90, choose F90.9 (unspecified type) only when documentation doesn't support a more specific option: predominantly inattentive type (F90.0), predominantly hyperactive type (F90.1), combined type (F90.2) and other type (F90.8).
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 886 (Behavioral and Developmental Disorders, relative weight 1.8678), in MDC 19 (Mental Diseases and 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.
