About coding Clark's paralysis
The ICD-10-CM code for Clark's paralysis is G80.9 (Cerebral palsy, unspecified).
Within G80, choose G80.9 (unspecified) only when documentation doesn't support a more specific option: spastic quadriplegic cerebral palsy (G80.0), spastic diplegic cerebral palsy (G80.1), spastic hemiplegic cerebral palsy (G80.2), Athetoid cerebral palsy (G80.3), Ataxic cerebral palsy (G80.4) and other cerebral palsy (G80.8).
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.
