About H73.0

H73.0 is the ICD-10-CM diagnosis code for acute 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 3 subcodes must be used instead.

Within H73 (other disorders of tympanic membrane), H73.0 is specifically for acute myringitis. Related codes cover chronic myringitis (H73.1), unspecified myringitis (H73.2), other specified disorders of tympanic membrane (H73.8) and unspecified disorder of tympanic membrane (H73.9).

To report this condition, pick the subcode that matches the documentation: H73.00 (myringitis), H73.01 (myringitis) and H73.09 (myringitis).

Don't report H73.0 together with the conditions in its Excludes1 note: acute myringitis with otitis media (H65, H66).

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