About H73.00
H73.00 is the ICD-10-CM diagnosis code for unspecified 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 4 subcodes must be used instead.
Within H73.0, choose H73.00 (Unspecified acute myringitis) only when documentation doesn't support a more specific option: bullous myringitis (H73.01) and other acute myringitis (H73.09).
To report this condition, pick the subcode that matches the documentation: H73.001 (ear), H73.002 (ear), H73.003 (bilateral) and H73.009 (ear).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
