About coding benign shuddering attack
The ICD-10-CM code for benign shuddering attack is G25.83 (Benign shuddering attacks).
Within G25.8 (other specified extrapyramidal and movement disorders), G25.83 is specifically for benign shuddering attacks. Related codes cover Restless legs syndrome (G25.81), Stiff-man syndrome (G25.82) and other specified extrapyramidal and movement disorders (G25.89).
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.
