About G97.84
G97.84 is the ICD-10-CM diagnosis code for intracranial hypotension following other procedure. It belongs to category G97 (intraoperative and postprocedural complications and disorders of nervous system, not elsewhere classified), 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 G97.8, choose G97.84 (Intracranial hypotension following other procedure) only when documentation doesn't support a more specific option: other intraoperative complications of nervous system (G97.81), other postprocedural complications and disorders of nervous system (G97.82) and intracranial hypotension following lumbar cerebrospinal fluid shunting (G97.83).
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 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 01 (Diseases and Disorders of the Nervous System) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), 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 was added in FY2021, effective October 1, 2020.
