About H73.01

H73.01 is the ICD-10-CM diagnosis code for bullous myringitis. It belongs to category H73 (other disorders of tympanic membrane), 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 4 subcodes must be used instead.

Within H73.0 (acute myringitis), H73.01 is specifically for bullous myringitis. Related codes cover unspecified acute myringitis (H73.00) and other acute myringitis (H73.09).

To report this condition, pick the subcode that matches the documentation: H73.011 (right ear), H73.012 (left ear), H73.013 (bilateral) and H73.019 (unspecified ear).

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