About coding Déjérine-Roussy syndrome
The ICD-10-CM code for Déjérine-Roussy syndrome is G89.0 (Central pain syndrome).
Within G89 (pain, not elsewhere classified), G89.0 is specifically for central pain syndrome. Related codes cover acute pain, not elsewhere classified (G89.1), chronic pain, not elsewhere classified (G89.2), neoplasm related pain (acute) (chronic) (G89.3) and chronic pain syndrome (G89.4).
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.
