ICD-10 Code H73.001 – Acute myringitis, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.001 – Acute myringitis, right ear
What it is
H73.001 identifies acute inflammation of the right tympanic membrane, also called the eardrum. Use it when the documentation specifically states acute myringitis affecting the right ear.
Clinical signs
Typical findings may include ear pain, a red or inflamed tympanic membrane, and visible blistering or irritation of the eardrum. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents acute myringitis and clearly specifies the right ear. It is appropriate for encounters focused on an acute eardrum infection or inflammation in the right ear.
If the note mentions myringitis without laterality, check whether a more specific code is documented. If the record instead describes otitis media or another ear disorder, code the stated condition.
Do not use for
Do not use H73.001 for left or bilateral myringitis, or for nonspecific ear pain without a diagnosis. Do not use it when the chart documents a different middle ear condition.
Coding tip
Always confirm laterality in the provider note before assigning H73.001.
