ICD-10 Code H73.099 – Other acute myringitis, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.099 – Other acute myringitis, unspecified ear
What it is
H73.099 identifies acute inflammation of the eardrum when the ear is not specified. Use it when documentation states myringitis but does not identify a left or right ear.
Clinical signs
Typical findings include ear pain, a red or inflamed tympanic membrane, and possible hearing discomfort. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents acute myringitis and does not name the affected ear. It also fits cases described as other acute myringitis with no more specific ear laterality recorded. Check documentation if the note is unclear or conflicts with the diagnosis.
Do not use for
Do not use H73.099 if the record specifies the left or right ear. Do not use it for otitis media or other middle-ear disorders unless the provider clearly documents myringitis.
Coding tip
Always look for laterality in the assessment, exam, or final diagnosis before assigning this unspecified-ear code.
