ICD-10 Code H74.4 – Polyp of middle ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H74.4 – Polyp of middle ear
What it is
H74.4 identifies a polyp arising in the middle ear. Use it when documentation describes a polypoid lesion in the middle ear space, usually noted on otologic examination or imaging.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include a visible aural mass, chronic ear drainage, or conductive hearing complaints, but you should code only what is documented.
When to use this code
Use H74.4 when the clinician specifically documents a polyp of the middle ear or a middle ear polypoid lesion. This code may fit ENT notes, operative reports, or follow-up visits describing the lesion without another more specific diagnosis.
If the record identifies another underlying ear disorder, code the documented condition as directed by the chart. Check documentation when the note is unclear about the exact anatomic site.
Do not use for
Do not use this code for external ear polyps, nasal polyps, or nonspecific ear masses without middle ear involvement. If the finding is elsewhere or unspecified, check documentation.
Coding tip
Confirm the provider names the middle ear specifically; wording such as “ear polyp” alone is not enough.
