H95.52Postprocedural hematoma of ear and mastoid process following other procedure

H95.52 is the ICD-10-CM diagnosis code for postprocedural hematoma of ear and mastoid process following 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 H95.5, choose H95.52 (hematoma of ear and mastoid process following other procedure) only when documentation doesn't support a more specific option: hematoma of ear and mastoid process following a procedure on the ear and mastoid process (H95.51), seroma of ear and mastoid process following a procedure on the ear and mastoid process (H95.53) and seroma of ear and mastoid process following other procedure (H95.54).

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 998.12 (hematoma complicating a procedure).
