About coding Intention tremor
The ICD-10-CM code for Intention tremor is G25.2 (Other specified forms of tremor).
Within G25, choose G25.2 (Other specified forms of tremor) only when documentation doesn't support a more specific option: essential tremor (G25.0), drug-induced tremor (G25.1), 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), other specified extrapyramidal and movement disorders (G25.8) and 1 more.
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.
