ICD-10 Code H73.09 – Other acute myringitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.09 – Other acute myringitis
What it is
H73.09 identifies acute inflammation of the tympanic membrane, or eardrum, when the record specifies a form other than the standard acute myringitis description. Use it for a documented eardrum inflammatory condition, not for middle-ear disease alone.
Clinical signs
Findings may include ear pain, a red or inflamed tympanic membrane, and possible hearing discomfort. Clinical features vary; refer to documentation for the exact type and whether the eardrum is the primary site.
When to use this code
Use H73.09 when the provider documents other acute myringitis, acute inflammation of the eardrum, or a similar specific diagnosis. It fits cases where the note clearly points to tympanic membrane involvement rather than nonspecific ear pain. Check documentation if otitis media or external ear disease is also mentioned.
Do not use for
Do not use this code for chronic myringitis, otitis media, or nonspecific ear symptoms without eardrum inflammation. If the record is unclear, check documentation.
Coding tip
Code only when the provider names acute myringitis or an equivalent eardrum diagnosis; otherwise, query for clarification.
