G96.12Meningeal adhesions (cerebral) (spinal)

G96.12 is the ICD-10-CM diagnosis code for meningeal adhesions (cerebral) (spinal). It belongs to category G96 (other disorders of central nervous system), 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 G96.1 (disorders of meninges, not elsewhere classified), G96.12 is specifically for meningeal adhesions (cerebral) (spinal). Related codes cover dural tear (G96.11) and other disorders of meninges, not elsewhere classified (G96.19).

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.

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 349.2 (disorders of meninges, not elsewhere classified).
