ICD-10 Code C44.29 – Other specified malignant neoplasm of skin of ear and external auricular canal (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.29 – Other specified malignant neoplasm of skin of ear and external auricular canal
What it is
This code identifies a malignant skin tumor located on the ear or external ear canal when the record specifies a skin cancer type not named by a more specific ear skin code. Use it for documented malignant neoplasms of this site.
Clinical signs
Findings may include a persistent nonhealing lesion, ulceration, crusting, bleeding, or a visible mass on the ear or in the external auricular canal. Clinical features vary; refer to documentation.
When to use this code
Use C44.29 when the clinician documents a malignant neoplasm of the skin of the ear or external auricular canal and no more specific code applies. It fits pathology-confirmed skin cancer at this site, including cases described as “other specified” malignant skin neoplasm. Check documentation if the lesion site or histology is unclear.
Do not use for
Do not use this code for benign skin lesions, nonmelanoma conditions not documented as malignant, or cancers arising from deeper ear structures rather than skin. If the chart does not clearly identify the site or malignancy, check documentation.
Coding tip
Code the exact anatomic site and malignant wording from the pathology or provider note before assigning C44.29.
