ICD-10 Code H73.1 – Chronic Myringitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.1 – Chronic myringitis
What it is
H73.1 identifies chronic inflammation of the tympanic membrane, also called the eardrum. Use it when documentation specifically states chronic myringitis or a persistent inflammatory change of the membrane.
Clinical signs
Typical findings may include a chronically inflamed or thickened tympanic membrane, with ear discomfort or discharge noted in the chart. Clinical features vary; refer to documentation.
When to use this code
Use H73.1 when the provider documents chronic myringitis as the diagnosis, including persistent eardrum inflammation seen on otoscopic exam. It is also appropriate when the record clearly links symptoms to chronic tympanic membrane inflammation. Check documentation if the term is used loosely or if another ear condition is the primary diagnosis.
Do not use for
Do not use this code for acute myringitis, otitis media, or nonspecific ear pain without documentation of chronic tympanic membrane inflammation. If the note does not specify chronic myringitis, check documentation.
Coding tip
Code H73.1 only when the provider names chronic myringitis; otherwise, query or code the documented ear condition.
