G97.63Postprocedural seroma of a nervous system organ or structure following a nervous system procedure

G97.63 is the ICD-10-CM diagnosis code for postprocedural seroma of a nervous system organ or structure following a nervous system 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 G97.6 (postprocedural hematoma and seroma of a nervous system organ or structure following a procedure), G97.63 is specifically for postprocedural seroma of a nervous system organ or structure following a nervous system procedure. Related codes cover hematoma of a nervous system organ or structure following a nervous system procedure (G97.61), hematoma of a nervous system organ or structure following other procedure (G97.62) and seroma of a nervous system organ or structure following other procedure (G97.64).

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 919 (Complications of Treatment with MCC, relative weight 1.763), DRG 920 (Complications of Treatment with CC, relative weight 0.9975) and DRG 921 (Complications of Treatment without CC/MCC, relative weight 0.6722), in MDC 21 (Injuries, Poisonings and Toxic Effects of Drugs), 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 FY2017, effective October 1, 2016.

Before ICD-10, this condition was coded in ICD-9-CM as 998.13 (seroma complicating a procedure).
