ICD-10 code for Imbalance
From the official ICD-10-CM alphabetic index entry “Imbalance”. Page updated September 29, 2026.
About coding Imbalance
The ICD-10-CM code for Imbalance is R26.89 (Other abnormalities of gait and mobility). The official index lists 17 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R26.89.
Within R26.8, choose R26.89 (Other abnormalities of gait and mobility) only when documentation doesn't support a more specific option: 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 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.
