ICD-10 Code C44.310 – Basal cell carcinoma of skin of unspecified parts of face (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.310 – Basal cell carcinoma of skin of unspecified parts of face
What it is
This code identifies basal cell carcinoma, a common skin cancer, located on an unspecified part of the face. Use it when the record confirms facial BCC but does not name the exact facial site.
Clinical signs
Typical findings include a pearly or translucent papule, rolled border, surface telangiectasia, or a nonhealing lesion that may bleed easily. Clinical features vary; refer to documentation.
When to use this code
Use C44.310 when the provider documents basal cell carcinoma of the face and the chart does not specify the eyelid, nose, ear, lip, or another exact facial location. It also fits pathology-confirmed BCC with only a general facial site noted. If the site is more specific, code that site instead.
Do not use for
Do not use this code for squamous cell carcinoma, melanoma, or benign skin lesions. Do not use it when the documentation identifies a more specific facial subsite.
Coding tip
Check the operative note, pathology report, and assessment for the exact facial location before assigning this unspecified-site code.
