ICD-10 Code C44.729 – Squamous cell carcinoma of skin of left lower limb, including hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.729 – Squamous cell carcinoma of skin of left lower limb, including hip
What it is
This code identifies squamous cell carcinoma arising in the skin of the left lower limb, including the hip. Use it when documentation specifies a primary skin cancer at that exact site.
Clinical signs
Typical findings include a persistent, enlarging skin lesion that may be scaly, crusted, ulcerated, or bleed easily. Clinical features vary; refer to documentation and pathology when available.
When to use this code
Use C44.729 when the provider documents squamous cell carcinoma of the skin on the left leg, ankle, foot, or hip region. It is appropriate for confirmed primary skin cancer at that location, including biopsy-proven cases. If the chart only says “skin cancer” or the site is unclear, check documentation.
Do not use for
Do not use this code for squamous cell carcinoma at a different body site or for non-squamous skin cancers. Do not apply it when the record does not identify the left lower limb or hip.
Coding tip
Confirm both histology and exact laterality/site before assigning this code.
