ICD-10 Code for Gait abnormality
The ICD-10-CM code for gait abnormality is R26.9 — Unspecified abnormalities of gait and mobility. This is the code the Alphabetic Index gives for gait abnormality with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
R26.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
