About coding Marmoratus status
The ICD-10-CM code for Marmoratus status is G80.3 (Athetoid cerebral palsy).
Within G80 (cerebral palsy), G80.3 is specifically for Athetoid cerebral palsy. Related codes cover spastic quadriplegic cerebral palsy (G80.0), spastic diplegic cerebral palsy (G80.1), spastic hemiplegic cerebral palsy (G80.2), Ataxic cerebral palsy (G80.4), other cerebral palsy (G80.8) and unspecified (G80.9).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
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.
