ICD-10 Code C44.519 – Basal cell carcinoma of skin of other part of trunk (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.519 – Basal cell carcinoma of skin of other part of trunk
What it is
This code identifies a basal cell carcinoma located on the trunk in a site other than the chest, abdomen, or back. It is a malignant skin tumor arising from basal cells and documented as being on another trunk location.
Clinical signs
Typical findings include a slow-growing skin lesion with pearly or translucent borders, possible ulceration, and surface bleeding. Clinical features vary; refer to documentation.
When to use this code
Use C44.519 when the provider documents basal cell carcinoma and specifies a trunk site that is not otherwise classified as chest, abdomen, or back. You should also use it when the lesion is described as another part of the trunk, such as a flank or side of the trunk, if documented clearly.
Do not use for
Do not use this code for basal cell carcinoma of the face, scalp, neck, extremities, or for trunk sites with a more specific ICD-10 code. Check documentation if the anatomic site is unclear.
Coding tip
Code the exact documented site first; if the location is nonspecific, query before assigning C44.519.
