ICD-10 Code H61.023 – Chronic perichondritis of external ear, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.023 – Chronic perichondritis of external ear, bilateral
What it is
This code identifies long-lasting inflammation of the perichondrium, the tissue around the cartilage of both external ears. It indicates a bilateral ear cartilage infection or inflammation that is chronic rather than acute.
Clinical signs
Typical findings include persistent auricular pain, swelling, tenderness, and redness involving both ears. Clinical features vary; refer to documentation.
When to use this code
Use H61.023 when the provider documents chronic perichondritis affecting both external ears. Code it when the record clearly states bilateral involvement, even if the note describes ongoing inflammation, recurrent infection, or chronic ear cartilage irritation.
Check documentation if the site is unclear or if the condition is described as acute, unilateral, or nonspecific ear pain without perichondrial involvement.
Do not use for
Do not use this code for acute perichondritis, isolated otitis externa, or nonspecific auricular cellulitis unless the provider specifically identifies chronic perichondritis. Check documentation.
Coding tip
Confirm both chronicity and bilateral external ear involvement in the provider’s documentation before assigning H61.023.
