About R25

R25 is the ICD-10-CM diagnosis code for abnormal involuntary movements. It belongs to block R25-R29 (symptoms and signs involving the nervous and musculoskeletal systems) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: R25.0 (movements), R25.1 (unspecified), R25.2 (spasm), R25.3 (Fasciculation), R25.8 (movements) and R25.9 (movements).

Don't report R25 together with the conditions in its Excludes1 note: specific movement disorders (G20-G26), stereotyped movement disorders (F98.4) and tic disorders (F95.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
