ICD-10 Code C44.201 – Unspecified malignant neoplasm of skin of unspecified ear and external auricular canal (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.201 – Unspecified malignant neoplasm of skin of unspecified ear and external auricular canal
What it is
This code identifies a malignant skin tumor on the ear or external ear canal when the exact site is not specified. Use it when documentation confirms skin cancer but does not name the ear subsite.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include a persistent nonhealing lesion, ulceration, bleeding, crusting, or a visible mass on the ear or in the external auricular canal.
When to use this code
Use this code when the record states malignant neoplasm of skin involving the ear, but laterality or precise location is missing. It also fits when the external auricular canal is involved and the chart remains nonspecific.
If pathology, operative notes, or clinician documentation gives a more exact site, code that specific option instead. Check documentation before assigning this unspecified code.
Do not use for
Do not use it for benign skin lesions, carcinoma in situ, or melanoma unless the chart clearly supports those diagnoses. Avoid this code when a more specific ear or external ear canal skin cancer code is documented.
Coding tip
Query for laterality and exact ear subsite whenever the note says only “ear skin cancer.”
