About F90.2
F90.2 is the ICD-10-CM diagnosis code for Attention-deficit hyperactivity disorder, combined type. It belongs to category F90 (Attention-deficit hyperactivity disorders), block F90-F98 (behavioral and emotional disorders with onset usually occurring in childhood and adolescence) 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 F90 (Attention-deficit hyperactivity disorders), F90.2 is specifically for Attention-deficit hyperactivity disorder, combined type. Related codes cover predominantly inattentive type (F90.0), predominantly hyperactive type (F90.1), other type (F90.8) and unspecified type (F90.9).
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.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 314.01 (attention deficit disorder with hyperactivity).
