ICD-10 Code H61.002 – Unspecified perichondritis of left external ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.002 – Unspecified perichondritis of left external ear
What it is
Use this code for inflammation of the cartilage covering the left external ear when the record does not identify a more specific cause. It indicates perichondritis limited to the left ear’s outer cartilage.
Clinical signs
Typical findings include redness, swelling, tenderness, and warmth of the external ear, often sparing the earlobe. Clinical features vary; refer to documentation.
When to use this code
Assign H61.002 when the clinician documents perichondritis of the left external ear and does not specify an organism, injury, or other cause. Use it for nonspecific or unspecified cases in the left ear only. If documentation identifies a more specific condition, code that instead.
Do not use for
Do not use this code for cellulitis, otitis externa, or perichondritis of the right ear or both ears. Check documentation if the note suggests trauma, piercing-related infection, or another defined etiology.
Coding tip
Verify laterality and whether the provider truly means perichondritis, since external ear infections are often documented imprecisely.
