About H73

H73 is the ICD-10-CM diagnosis code for other disorders of tympanic membrane. It belongs to block H65-H75 (diseases of middle ear and mastoid) 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 5 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: H73.0 (myringitis), H73.1 (myringitis), H73.2 (myringitis), H73.8 (membrane) and H73.9 (membrane).

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