ICD-10 Code C44.71 – Basal cell carcinoma of skin of lower limb, including hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.71 – Basal cell carcinoma of skin of lower limb, including hip
What it is
This code identifies basal cell carcinoma, a common skin cancer, when it is located on the lower limb or hip. Use it for the documented anatomic site, not for other skin cancers or unspecified locations.
Clinical signs
Typical findings include a slow-growing skin lesion that may appear pearly, shiny, pink, or ulcerated. Clinical features vary; refer to documentation and pathology when available.
When to use this code
Use C44.71 when the provider documents basal cell carcinoma on the leg, ankle, foot, or hip region. It also applies when pathology or clinical assessment confirms basal cell carcinoma at that site. If the note does not specify the lower limb or hip, check documentation before assigning this code.
Do not use for
Do not use this code for basal cell carcinoma at another body site or for squamous cell carcinoma, melanoma, or benign skin lesions. Check documentation if the lesion site is unclear or described only as “skin cancer.”
Coding tip
Match the code to the exact documented lesion site and confirm that the diagnosis is basal cell carcinoma before coding.
