About coding child hyperactive
The ICD-10-CM code for child hyperactive is F90.9 (Attention-deficit hyperactivity disorder, unspecified type).
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.
