About R26.2

R26.2 is the ICD-10-CM diagnosis code for difficulty in walking, not elsewhere classified. 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within R26 (abnormalities of gait and mobility), R26.2 is specifically for difficulty in walking, not elsewhere classified. Related codes cover Ataxic gait (R26.0), paralytic gait (R26.1), other abnormalities of gait and mobility (R26.8) and unspecified abnormalities of gait and mobility (R26.9).

Don't report R26.2 together with the conditions in its Excludes1 note: falling (R29.6).

The conditions in its Excludes2 note aren't part of R26.2, but may be coded alongside it if the patient has both: unsteadiness on feet (R26.81).

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 555 (Signs and Symptoms of Musculoskeletal System and Connective Tissue with MCC, relative weight 1.2913) and DRG 556 (Signs and Symptoms of Musculoskeletal System and Connective Tissue without MCC, relative weight 0.8211), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), 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 719.7 (difficulty in walking).
