ICD-10 code for extrapyramidal disorder

The ICD-10-CM code for extrapyramidal disorder is G25.9 (Extrapyramidal and movement disorder, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on G25.9.

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.
