H95.1Other disorders of ear and mastoid process following mastoidectomy

H95.1 is the ICD-10-CM diagnosis code for other disorders of ear and mastoid process following mastoidectomy. 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 4 subcodes must be used instead.

Within H95, choose H95.1 (Other disorders of ear and mastoid process following mastoidectomy) only when documentation doesn't support a more specific option: recurrent cholesteatoma of postmastoidectomy cavity (H95.0), 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 hemorrhage of ear and mastoid process following a procedure (H95.4), 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: H95.11 (cavity), H95.12 (cavity), H95.13 (cavity) and H95.19 (mastoidectomy).

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