About coding Hyperperfusion syndrome
The ICD-10-CM code for Hyperperfusion syndrome is G97.82 (Other postprocedural complications and disorders of nervous system).
Within G97.8, choose G97.82 (Other postprocedural complications and disorders of nervous system) only when documentation doesn't support a more specific option: other intraoperative complications of nervous system (G97.81), intracranial hypotension following lumbar cerebrospinal fluid shunting (G97.83) and intracranial hypotension following other procedure (G97.84).
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.
