About coding medullaris syndrome conus
The ICD-10-CM code for medullaris syndrome conus is G95.81 (Conus medullaris syndrome).
Within G95.8 (other specified diseases of spinal cord), G95.81 is specifically for Conus medullaris syndrome. Related codes cover other specified diseases of spinal cord (G95.89).
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 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.
