Melanoma in situ of right lower limb, including hip

This code signifies the presence of melanoma that is confined to the epidermis (in situ) on the right lower limb, which includes the hip region. This is a non-invasive form of skin cancer where malignant cells have not spread beyond the outermost layer of the skin.

Apply this code when documentation clearly states a diagnosis of melanoma in situ located anywhere on the patient's right lower extremity, including the hip. Supporting documentation would include pathology reports confirming melanoma in situ and physician notes specifying the laterality and anatomical site.

• Ensure the documentation specifies "in situ" to differentiate from invasive melanoma.
• Verify laterality; this code is specific to the right lower limb.
• Do not use for melanoma of the trunk, upper limb, or other specified sites.
