ICD-10 Code C44.719 – Basal cell carcinoma of skin of left lower limb, including hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.719 – Basal cell carcinoma of skin of left lower limb, including hip
What it is
C44.719 identifies basal cell carcinoma, a common skin cancer, in the skin of the left lower limb, including the hip. Use it when documentation specifies this exact site and histology.
Clinical signs
Typical findings include a slowly enlarging skin lesion, pearly or translucent borders, ulceration, or a nonhealing sore. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents basal cell carcinoma on the left leg, thigh, knee, lower leg, ankle, foot, or hip region, and the laterality is left. It fits confirmed primary skin malignancy at that site. If the record only says “skin cancer” or the site is unclear, check documentation.
Do not use for
Do not use it for basal cell carcinoma on the right lower limb or on an unspecified site. It is also not for other skin cancers or metastatic disease.
Coding tip
Verify both the histology and left-sided anatomic site before assigning C44.719.
