R26.8Other abnormalities of gait and mobility

R26.8 is the ICD-10-CM diagnosis code for other abnormalities of gait and mobility. It belongs to category R26 (abnormalities of gait and mobility), 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 2 subcodes must be used instead.

Within R26, choose R26.8 (Other abnormalities of gait and mobility) only when documentation doesn't support a more specific option: Ataxic gait (R26.0), paralytic gait (R26.1), difficulty in walking, not elsewhere classified (R26.2) and unspecified abnormalities of gait and mobility (R26.9).

To report this condition, pick the subcode that matches the documentation: R26.81 (feet) and R26.89 (mobility).

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