ICD-10 Code C44.619 – Basal cell carcinoma of skin of left upper limb, including shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.619 – Basal cell carcinoma of skin of left upper limb, including shoulder
What it is
This code identifies basal cell carcinoma located on the skin of the left upper limb, including the shoulder. It is a malignant skin tumor that arises from basal cells and is documented by anatomic site.
Clinical signs
Typical findings include a slow-growing skin lesion that may appear pearly, translucent, pink, or ulcerated. Clinical features vary; refer to documentation.
When to use this code
Use C44.619 when the provider documents basal cell carcinoma specifically on the left arm, forearm, upper arm, or shoulder skin. You should code the documented laterality and site as recorded in the note.
If the record says only “basal cell carcinoma” without a more specific site, check documentation before assigning this code. Use the exact anatomic location when it is clearly stated.
Do not use for
Do not use this code for basal cell carcinoma on the right upper limb, trunk, face, or other body sites. Do not use it when documentation is nonspecific or when another skin cancer type is stated.
Coding tip
Verify laterality and the exact skin site in the pathology or provider note before coding.
