About coding tympanic membrane disorder
The ICD-10-CM code for tympanic membrane disorder is H73.9 (Unspecified disorder of tympanic membrane). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on H73.9.
Within H73, choose H73.9 (Unspecified disorder of tympanic membrane) only when documentation doesn't support a more specific option: acute myringitis (H73.0), chronic myringitis (H73.1), unspecified myringitis (H73.2) and other specified disorders of tympanic membrane (H73.8).
To report this condition, pick the subcode that matches the documentation: H73.90 (unspecified ear), H73.91 (right ear), H73.92 (left ear) and H73.93 (bilateral).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
