About coding myelopathy
The ICD-10-CM code for myelopathy is G95.9 (Disease of spinal cord, unspecified). The official index lists 10 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on G95.9.
Within G95, choose G95.9 (Disease of spinal cord, unspecified) only when documentation doesn't support a more specific option: Syringomyelia and syringobulbia (G95.0), vascular myelopathies (G95.1), other and unspecified cord compression (G95.2) and other specified diseases of spinal cord (G95.8).
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), DRG 093 (Other Disorders of Nervous System without CC/MCC, relative weight 0.7783), 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.
