ICD-10 Code C44.320 – Squamous cell carcinoma of skin of unspecified parts of face (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.320 – Squamous cell carcinoma of skin of unspecified parts of face
What it is
This code identifies a malignant squamous cell carcinoma arising in the skin of the face when the exact facial site is not documented. Use it for nonmelanoma skin cancer, not for mucosal or internal squamous cell tumors.
Clinical signs
Typical findings include a persistent scaly, crusted, or ulcerated facial lesion that may enlarge or bleed. Clinical features vary; refer to documentation.
When to use this code
Use C44.320 when the provider documents squamous cell carcinoma of the skin on the face but does not specify the exact facial subsite. It also fits pathology-confirmed facial skin SCC when the record only says “face” or “facial skin.”
Do not use for
Do not use this code if the lesion is on a more specific facial site that has its own ICD-10 code, or if the diagnosis is not skin-based. Check documentation.
Coding tip
Code the most specific facial site available; if the note only says “face,” C44.320 is appropriate.
