H95.22Intraoperative hemorrhage and hematoma of ear and mastoid process complicating other procedure

H95.22 is the ICD-10-CM diagnosis code for intraoperative hemorrhage and hematoma of ear and mastoid process complicating other procedure. It belongs to category H95 (intraoperative and postprocedural complications and disorders of ear and mastoid process, not elsewhere classified), block H95 (intraoperative and postprocedural complications and disorders of ear and mastoid process, not elsewhere classified) and chapter 8 (diseases of the ear and mastoid process). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within H95.2, choose H95.22 (other procedure) only when documentation doesn't support a more specific option: on the ear and mastoid process (H95.21).

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).
