ICD-10 Code H73.091 – Other acute myringitis, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.091 – Other acute myringitis, right ear
What it is
H73.091 identifies acute inflammation of the right tympanic membrane, or eardrum, when the condition is classified as other acute myringitis. Use it when documentation specifies the right ear.
Clinical signs
Typical findings may include ear pain, redness, and a visibly inflamed tympanic membrane. Clinical features vary; refer to documentation for laterality and whether the diagnosis is acute myringitis rather than another ear disorder.
When to use this code
Use this code when the provider documents other acute myringitis affecting the right ear. It is appropriate when the record clearly identifies acute inflammation of the eardrum and specifies the side. Check documentation if the note only says ear pain or otitis without myringitis.
Do not use for
Do not use it for unspecified ear inflammation, chronic myringitis, or conditions involving the left ear or both ears. If the chart does not clearly support myringitis, check documentation.
Coding tip
Confirm both acuity and laterality in the provider note before assigning H73.091.
