G25.9Extrapyramidal and movement disorder, unspecified

G25.9 is the ICD-10-CM diagnosis code for extrapyramidal and movement disorder, unspecified. It belongs to category G25 (other extrapyramidal and movement disorders), block G20-G26 (extrapyramidal and movement disorders) and chapter 6 (diseases of the nervous system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within G25, choose G25.9 (Extrapyramidal and movement disorder, unspecified) only when documentation doesn't support a more specific option: essential tremor (G25.0), drug-induced tremor (G25.1), other specified forms of tremor (G25.2), myoclonus (G25.3), drug-induced chorea (G25.4), other chorea (G25.5), drug induced tics and other tics of organic origin (G25.6), other and unspecified drug induced movement disorders (G25.7) and 1 more.

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 056 (Degenerative Nervous System Disorders with MCC, relative weight 2.2655) and DRG 057 (Degenerative Nervous System Disorders without MCC, relative weight 1.2838), 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.

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 333.90 (unspecified extrapyramidal disease and abnormal movement disorder).
