About coding Staggering gait abnormality
The ICD-10-CM code for Staggering gait abnormality is R26.0 (Ataxic gait).
Within R26 (abnormalities of gait and mobility), R26.0 is specifically for Ataxic gait. Related codes cover paralytic gait (R26.1), difficulty in walking, not elsewhere classified (R26.2), other abnormalities of gait and mobility (R26.8) and unspecified abnormalities of gait and mobility (R26.9).
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 091 (Other Disorders of Nervous System with MCC, relative weight 1.7046), DRG 092 (Other Disorders of Nervous System with CC, relative weight 1.0239) and DRG 093 (Other Disorders of Nervous System without CC/MCC, relative weight 0.7783), in MDC 01 (Diseases and Disorders of the Nervous System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
