ICD-10 Code H61.022 – Chronic perichondritis of left external ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.022 – Chronic perichondritis of left external ear
What it is
This code identifies long-lasting inflammation of the cartilage and surrounding tissue of the left external ear. It is used when the condition is specifically documented as chronic and limited to the left ear.
Clinical signs
Typical findings include persistent ear pain, swelling, redness, and tenderness of the outer ear. Clinical features vary; refer to documentation for evidence of chronic perichondrial involvement and left-sided location.
When to use this code
Use H61.022 when the provider documents chronic perichondritis affecting the left external ear. This may appear in outpatient follow-up, specialty consultation, or problem list documentation when the diagnosis is established. Check documentation if laterality or chronicity is unclear.
Do not use for
Do not use this code for acute perichondritis, unspecified ear involvement, or conditions limited to the skin of the ear. If the record does not confirm the left side, check documentation.
Coding tip
Capture both chronicity and laterality exactly as documented before assigning H61.022.
