ICD-10 Code H73.13 – Chronic myringitis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.13 – Chronic myringitis, bilateral
What it is
H73.13 identifies chronic inflammation of the tympanic membrane in both ears. Use it when documentation clearly states chronic myringitis affecting the right and left sides.
Clinical signs
Typical findings may include persistent eardrum irritation, redness, thickening, or granulation on otoscopic exam. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents chronic myringitis as bilateral, or states involvement of both tympanic membranes. It may appear in follow-up notes for ongoing ear inflammation or recurrent otoscopic abnormalities. If laterality is not documented, check documentation before assigning H73.13.
Do not use for
Do not use this code for acute myringitis, isolated otitis externa, or nonspecific ear pain without documented tympanic membrane inflammation. Check documentation.
Coding tip
Confirm both chronicity and bilateral laterality in the chart before coding H73.13.
