About E36.02

E36.02 is the ICD-10-CM diagnosis code for intraoperative hemorrhage and hematoma of an endocrine system organ or structure complicating other procedure. It belongs to category E36 (intraoperative complications of endocrine system), block E36 (intraoperative complications of endocrine system) 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 E36.0, choose E36.02 (other procedure) only when documentation doesn't support a more specific option: an endocrine system procedure (E36.01).

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 has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 998.11 (hemorrhage complicating a procedure) and 998.12 (hematoma complicating a procedure).
