About coding organic graphospasm
The ICD-10-CM code for organic graphospasm is G25.89 (Other specified extrapyramidal and movement disorders).
Within G25.8, choose G25.89 (Other specified extrapyramidal and movement disorders) only when documentation doesn't support a more specific option: Restless legs syndrome (G25.81), Stiff-man syndrome (G25.82) and benign shuddering attacks (G25.83).
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 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.
