ICD-10 Code D03.71 – Melanoma in situ of right lower limb, including hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D03.71 – Melanoma in situ of right lower limb, including hip
What it is
This code identifies melanoma in situ confined to the skin of the right lower limb, including the hip. “In situ” means the abnormal melanocytes have not invaded deeper tissue.
Clinical signs
Findings usually include a suspicious pigmented lesion with asymmetry, irregular borders, color variation, or change over time. Clinical features vary; refer to documentation.
When to use this code
Use D03.71 when the provider documents melanoma in situ on the right leg, thigh, knee, lower leg, ankle, foot, or hip. The diagnosis should clearly state the right-sided location and that the lesion is in situ. If the site is not specified or invasion is documented, check documentation.
Do not use for
Do not use this code for invasive melanoma, melanoma in situ on the left side, or lesions on other body sites. Check documentation if the record only says “melanoma” without an in situ designation.
Coding tip
Confirm both laterality and the exact anatomic site before assigning D03.71.
