ICD-10 Code C43.71 – Malignant melanoma of right lower limb, including hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C43.71 – Malignant melanoma of right lower limb, including hip
What it is
C43.71 identifies a malignant melanoma located on the right lower limb, including the hip. Use it when the documentation confirms primary skin melanoma at that site.
Clinical signs
Clinical features vary; refer to documentation. Melanoma is often described as an irregular, changing pigmented lesion, sometimes with asymmetry, uneven borders, color variation, or ulceration.
When to use this code
Use this code when the provider documents malignant melanoma of the right leg, ankle, foot, or hip region, and the laterality is right. It applies to the primary site on the skin, not to a metastatic focus. If the record only says “melanoma” without site or side, check documentation.
Do not use for
Do not use C43.71 for melanoma on the left lower limb, unspecified limb, or noncutaneous melanoma. Do not use it for a history of melanoma or for metastatic disease without primary right-lower-limb site documentation.
Coding tip
Verify both laterality and exact anatomic site in the note before assigning C43.71.
