ICD-10 Code C44.3 – Other and unspecified malignant neoplasm of skin of other and unspecified parts of face (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.3 – Other and unspecified 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 exact facial site is not specified or is described only as other parts of the face. Use it for documented cancer of facial skin that is not better localized.
Clinical signs
Clinical features vary; refer to documentation. Skin cancers may present as a nonhealing lesion, changing pigmented spot, ulcer, crusting, bleeding, or a firm nodule on the face.
When to use this code
Use C44.3 when the record states a malignant neoplasm of facial skin but does not name a more exact facial subsite. It also fits pathology or specialist notes that describe the lesion as other or unspecified parts of the face. If the site is clearly documented elsewhere, code that more specific location instead.
Do not use for
Do not use this code for benign skin lesions, carcinoma in situ, or non-facial skin cancers. If the chart gives a precise facial subsite, check documentation and select the narrower code.
Coding tip
Look for the most specific facial site in pathology, operative, or dermatology notes before assigning C44.3.
