ICD-10 Code C44.722 – Squamous cell carcinoma of skin of right lower limb, including hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.722 – Squamous cell carcinoma of skin of right lower limb, including hip
What it is
This code identifies a malignant squamous cell carcinoma arising in the skin of the right lower limb, including the hip. Use it when the record specifies this exact anatomic site and skin origin.
Clinical signs
Typical findings include a persistent, enlarging skin lesion that may be scaly, crusted, ulcerated, or bleeding. Clinical features vary; refer to documentation for biopsy-confirmed squamous cell carcinoma and the stated right lower limb location.
When to use this code
Use this code when the provider documents squamous cell carcinoma of the skin on the right leg, thigh, knee, lower leg, ankle, foot, or hip region. It is also appropriate when pathology or the assessment clearly supports a skin primary at this site. If the exact site is unclear, check documentation before coding.
Do not use for
Do not use this code for squamous cell carcinoma at a different body site or for non-skin malignancies. Do not assign it if the record only says “skin cancer” without confirming squamous cell carcinoma and the right lower limb location.
Coding tip
Verify both the histology and the exact laterality/site in the note, because C44.722 is site-specific.
