H95.4Postprocedural hemorrhage of ear and mastoid process following a procedure

H95.4 is the ICD-10-CM diagnosis code for postprocedural hemorrhage of ear and mastoid process following a 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 a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within H95 (intraoperative and postprocedural complications and disorders of ear and mastoid process, not elsewhere classified), H95.4 is specifically for postprocedural hemorrhage of ear and mastoid process following a procedure. Related codes cover recurrent cholesteatoma of postmastoidectomy cavity (H95.0), other disorders of ear and mastoid process following mastoidectomy (H95.1), intraoperative hemorrhage and hematoma of ear and mastoid process complicating a procedure (H95.2), accidental puncture and laceration of ear and mastoid process during a procedure (H95.3), postprocedural hematoma and seroma of ear and mastoid process following a procedure (H95.5) and other intraoperative and postprocedural complications and disorders of the ear and mastoid process, not elsewhere classified (H95.8).

To report this condition, pick the subcode that matches the documentation: H95.41 (on the ear and mastoid process) and H95.42 (procedure).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (title revised).
