ICD-10 Code C44.30 – Unspecified malignant neoplasm of skin of other and unspecified parts of face (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.30 – Unspecified malignant neoplasm of skin of other and unspecified parts of face
What it is
This code identifies a malignant skin tumor on the face when the exact facial site is not specified. Use it when documentation confirms skin cancer but does not name a more precise part of the face.
Clinical signs
Clinical features vary; refer to documentation. Commonly, skin cancers present as a persistent lesion, nonhealing sore, changing growth, or area of abnormal pigmentation on facial skin.
When to use this code
Use this code when the record states a malignant neoplasm of facial skin but does not identify a more specific facial location. It also fits when the site is documented only as “face” or “other unspecified parts of face.”
If pathology or provider notes later specify a more exact facial subsite, code that more precise diagnosis instead. Check documentation carefully before defaulting to an unspecified code.
Do not use for
Do not use this code for benign skin lesions, premalignant lesions, or non-skin cancers involving the face. Do not use it when the documentation gives a specific facial site that has its own code.
Coding tip
Query for the exact facial location when the note says only “facial skin cancer”; unspecified wording can change code selection.
