ICD-10 Code D03.72 – Melanoma in situ of left lower limb, including hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D03.72 – Melanoma in situ of left lower limb, including hip
What it is
This code identifies melanoma in situ located on the left lower limb, including the hip. The lesion is confined to the epidermis and has not invaded deeper tissue.
Clinical signs
You may see a new or changing pigmented skin lesion with asymmetry, irregular borders, color variation, or enlargement. Clinical features vary; refer to documentation and pathology confirmation when available.
When to use this code
Use D03.72 when the provider documents melanoma in situ specifically on the left lower limb or hip. It is appropriate when pathology or clinical assessment confirms in situ disease without invasion. If the site or laterality is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for invasive melanoma, unspecified skin cancer, or lesions on another body site. Do not use it when the record does not support left-sided lower-limb involvement.
Coding tip
Verify both laterality and the exact anatomic site in the pathology or operative note before coding.
