ICD-10 Code D04.72 – Carcinoma in situ of skin of left lower limb, including hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D04.72 – Carcinoma in situ of skin of left lower limb, including hip
What it is
This code identifies a noninvasive skin cancer confined to the epidermis on the left lower limb, including the hip. It means the abnormal cells have not penetrated deeper tissue.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include a persistent scaly, crusted, or erythematous lesion that is suspicious on examination and confirmed by pathology as carcinoma in situ.
When to use this code
Use D04.72 when the provider documents carcinoma in situ or intraepidermal carcinoma of the skin on the left leg or hip region. Code it when the lesion is specifically located on the left lower limb, including the hip, and the diagnosis is not invasive.
If the record only says “skin cancer” or the site is unclear, check documentation before coding. Confirm laterality and anatomic site from the pathology report, operative note, or assessment.
Do not use for
Do not use this code for invasive skin cancer, benign lesions, or lesions on the right lower limb or other body sites. Check documentation if the site is uncertain.
Coding tip
Verify both laterality and that the diagnosis is in situ before assigning D04.72.
