K91.873Postprocedural seroma of a digestive system organ or structure following other procedure

K91.873 is the ICD-10-CM diagnosis code for postprocedural seroma of a digestive system organ or structure following other procedure. It belongs to category K91 (intraoperative and postprocedural complications and disorders of digestive system, not elsewhere classified), block K90-K95 (other diseases of the digestive system) and chapter 11 (diseases of the digestive 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 K91.87, choose K91.873 (seroma of a digestive system organ or structure following other procedure) only when documentation doesn't support a more specific option: hematoma of a digestive system organ or structure following a digestive system procedure (K91.870), hematoma of a digestive system organ or structure following other procedure (K91.871) and seroma of a digestive system organ or structure following a digestive system procedure (K91.872).

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).
