About E89.822

E89.822 is the ICD-10-CM diagnosis code for postprocedural seroma of an endocrine system organ or structure following an endocrine system procedure. It belongs to category E89 (postprocedural endocrine and metabolic complications and disorders, not elsewhere classified), block E89 (postprocedural endocrine and metabolic complications and disorders, not elsewhere classified) and chapter 4 (endocrine, nutritional and metabolic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within E89.82 (postprocedural hematoma and seroma of an endocrine system organ or structure), E89.822 is specifically for postprocedural seroma of an endocrine system organ or structure following an endocrine system procedure. Related codes cover hematoma of an endocrine system organ or structure following an endocrine system procedure (E89.820), hematoma of an endocrine system organ or structure following other procedure (E89.821) and seroma of an endocrine system organ or structure following other procedure (E89.823).

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).
