ICD-10 Code H61.322 – Acquired stenosis of left external ear canal secondary to inflammation and infection (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.322 – Acquired stenosis of left external ear canal secondary to inflammation and infection
What it is
This code identifies a narrowed left external ear canal that developed after inflammation or infection. It reflects an acquired change, not a congenital or traumatic one.
Clinical signs
Typical findings include reduced canal diameter, difficulty visualizing the tympanic membrane, and symptoms such as blocked-ear sensation or hearing change. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states acquired stenosis of the left external auditory canal due to inflammation or infection. It is appropriate when the laterality is left and the cause is documented as inflammatory or infectious. If the note does not specify cause or side, check documentation.
Do not use for
Do not use it for congenital ear canal narrowing, traumatic stenosis, or unspecified external ear canal stenosis. Do not assume infection-related cause unless the provider documents it.
Coding tip
Match the side and etiology exactly as documented; if either is missing, query the provider before assigning H61.322.
