F82Specific developmental disorder of motor function

F82 is the ICD-10-CM diagnosis code for specific developmental disorder of motor function. It belongs to block F80-F89 (pervasive and specific developmental disorders) 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.

Don't report F82 together with the conditions in its Excludes1 note: abnormalities of gait and mobility (R26.-) and lack of coordination (R27.-).

The conditions in its Excludes2 note aren't part of F82, but may be coded alongside it if the patient has both: lack of coordination secondary to intellectual disabilities (F70-F79).

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 315.4 (developmental coordination disorder).
