About H95
H95 is the ICD-10-CM diagnosis code for intraoperative and postprocedural complications and disorders of ear and mastoid process, not elsewhere classified. It belongs to 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 7 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: H95.0 (cavity), H95.1 (mastoidectomy), H95.2 (procedure), H95.3 (procedure), H95.4 (procedure), H95.5 (procedure) and H95.8 (classified).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
