About G95.0

G95.0 is the ICD-10-CM diagnosis code for Syringomyelia and syringobulbia. It belongs to category G95 (other and unspecified diseases of spinal cord), block G89-G99 (other disorders of the nervous system) and chapter 6 (diseases of the nervous system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within G95 (other and unspecified diseases of spinal cord), G95.0 is specifically for Syringomyelia and syringobulbia. Related codes cover vascular myelopathies (G95.1), other and unspecified cord compression (G95.2), other specified diseases of spinal cord (G95.8) and disease of spinal cord, unspecified (G95.9).

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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 336.0 (Syringomyelia and syringobulbia).
