ICD-10 Code C44.300 – Unspecified malignant neoplasm of skin of unspecified part of face (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.300 – Unspecified malignant neoplasm of skin of unspecified part of face
What it is
This code identifies a malignant skin tumor on the face when the exact facial site is not documented. Use it when the record confirms skin cancer, but the provider does not specify a more precise facial location.
Clinical signs
Clinical features vary; refer to documentation. Skin cancer may present as a nonhealing lesion, changing pigmented spot, ulcer, or raised growth on the face, but the diagnosis should be based on the provider’s assessment.
When to use this code
Use C44.300 when the chart states malignant neoplasm of skin of the face and does not identify the nose, eyelid, ear, lip, or another facial subsite. It also fits when the lesion is described as facial skin cancer without further detail. If the note later specifies a site, code the more exact option.
Do not use for
Do not use this code for benign skin lesions, dysplastic nevi, or non-malignant tumors. Do not use it when documentation names a specific facial site or a different anatomic location.
Coding tip
Check the pathology or operative note for a more specific facial site before defaulting to this unspecified code.
