ICD-10 Code H73.00 – Unspecified Acute Myringitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.00 – Unspecified acute myringitis
What it is
H73.00 identifies acute inflammation of the tympanic membrane, or eardrum, when the type is not further specified. Use it when documentation says myringitis but does not name a more specific form.
Clinical signs
Common findings include ear pain, a red or inflamed tympanic membrane, and possible decreased hearing. Clinical features vary; refer to documentation.
When to use this code
Use H73.00 when the record clearly documents acute myringitis and does not provide a more specific subtype or cause. It may also fit when the provider describes eardrum inflammation without additional detail. If the note instead identifies otitis media or another ear disorder, code the documented condition.
Do not use for
Do not use this code for chronic myringitis or for middle-ear infections that are documented as otitis media. Check documentation.
Coding tip
Query the provider when “myringitis” is mentioned but acuity or specificity is unclear.
