About coding Encephalomyeloradiculopathy
The ICD-10-CM code for Encephalomyeloradiculopathy is G96.9 (Disorder of central nervous system, unspecified).
Within G96, choose G96.9 (Disorder of central nervous system, unspecified) only when documentation doesn't support a more specific option: cerebrospinal fluid leak (G96.0), disorders of meninges, not elsewhere classified (G96.1) and other specified disorders of central nervous system (G96.8).
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 070 (Other Cerebrovascular Disorders with MCC, relative weight 1.6093), DRG 071 (Other Cerebrovascular Disorders with CC, relative weight 1.0177), DRG 072 (Other Cerebrovascular Disorders without CC/MCC, relative weight 0.7348), DRG 974 (HIV with Major Related Condition with MCC, relative weight 3.0506), DRG 975 (HIV with Major Related Condition with CC, relative weight 1.3252) and DRG 976 (HIV with Major Related Condition without CC/MCC, relative weight 0.8124), in MDC 01 (Diseases and Disorders of the Nervous System) and MDC 25 (Human Immunodeficiency Virus Infections), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
