ICD-10 Code C44.390 – Other specified malignant neoplasm of skin of unspecified parts of face (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.390 – Other specified malignant neoplasm of skin of unspecified parts of face
What it is
This code identifies a malignant skin tumor on the face when the site is not further specified within the facial skin and the diagnosis does not fit a more specific code. Use it for documented cancer of the skin on an unspecified part of the face.
Clinical signs
Clinical features vary; refer to documentation. Skin cancer on the face may present as a persistent lesion, nonhealing area, or changing pigmented or raised spot, but the record should support a malignant diagnosis.
When to use this code
Use this code when the provider documents a malignant neoplasm of the skin on the face but does not identify a more exact facial subsite. It is appropriate when the chart supports a skin cancer diagnosis and the location is limited to unspecified facial skin. Check documentation if the lesion is described more precisely.
Do not use for
Do not use this code for benign skin lesions, precancerous changes, or non-malignant growths of the face. If the note identifies another facial subsite or a different skin cancer category, choose the more specific code.
Coding tip
Code only what the provider documents, and query for the exact facial site when the record is vague.
