About coding drug induced blepharospasm
The ICD-10-CM code for drug induced blepharospasm is G24.01 (Drug induced subacute dyskinesia).
Within G24.0 (drug induced dystonia), G24.01 is specifically for drug induced subacute dyskinesia. Related codes cover drug induced acute dystonia (G24.02) and other drug induced dystonia (G24.09).
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.
