H95.22 is a billable ICD-10-CM diagnosis code for intraoperative hemorrhage and hematoma of ear and mastoid process complicating other procedure. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 919 through 921. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 76 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Postprocedural or postoperative ear and/or mastoid process complication.

Questions About H95.22Overview

Is H95.22 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report intraoperative hemorrhage and hematoma of ear and mastoid process complicating other procedure on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does H95.22 group to?

When intraoperative hemorrhage and hematoma of ear and mastoid process complicating other procedure is the principal diagnosis on an inpatient stay, it groups to MS-DRG 920, 919, 921, with relative weights from 0.6719 to 1.7624 depending on complications. Higher weights mean higher Medicare reimbursement.

Is H95.22 a CC or MCC?

CMS lists H95.22 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 76 closely related codes in its exclusion list.

Can H95.22 be reported with a code from H95.3?

Not as a rule. The Excludes1 note at H95.2, which applies to H95.22, lists "intraoperative hemorrhage and hematoma of ear and mastoid process due to accidental puncture or laceration during a procedure (H95.3-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

What is the ICD-9 equivalent of H95.22?

Under the General Equivalence Mappings, intraoperative hemorrhage and hematoma of ear and mastoid process complicating other procedure converts to ICD-9-CM 998.11 (hemorrhage complic proc) and 998.12 (hematoma complic proc). The mapping is approximate, so confirm the match fits the documentation.
