ICD-10 Code C44.39 – Other specified malignant neoplasm of skin of other and unspecified parts of face (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.39 – Other specified malignant neoplasm of skin of other and unspecified parts of face
What it is
This code identifies a malignant skin cancer on the face when the site is other or not further specified. Use it for a documented facial skin malignancy that does not fit a more specific facial location code.
Clinical signs
Findings may include a persistent skin lesion, nonhealing ulcer, crusting, bleeding, or a changing pigmented or nonpigmented patch. Clinical features vary; refer to documentation.
When to use this code
Use C44.39 when the provider documents a malignant neoplasm of skin on the face and the record does not specify a more exact facial subsite. It is also appropriate when the lesion is described as other specified or unspecified parts of the face. Verify pathology, biopsy, or clinician documentation before assigning the code.
Do not use for
Do not use this code for benign, in situ, or uncertain skin lesions. If the facial site is specified more precisely, check documentation and select the more exact ICD-10 code.
Coding tip
Code from the most specific facial location documented, and use C44.39 only when the record supports an other or unspecified facial site.
