ICD-10 Code C76.52 – Malignant neoplasm of left lower limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C76.52 – Malignant neoplasm of left lower limb
What it is
This code identifies a malignant neoplasm in the left lower limb when the exact site is not specified more precisely. Use it for cancer documented in the left leg, foot, or other lower-limb area without a more specific anatomic code.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include a documented mass, pain, swelling, ulceration, or functional limitation in the left lower limb.
When to use this code
Use C76.52 when the provider documents a primary or secondary malignant neoplasm in the left lower limb and does not identify a more specific location. It is appropriate when the record states cancer of the left leg or left lower extremity without further detail. Check documentation if the site is bone, skin, or soft tissue and another code applies.
Do not use for
Do not use this code for benign tumors, uncertain behavior, or metastatic disease coded elsewhere. Also avoid it when documentation gives a more specific anatomic site or histology-based code.
Coding tip
Query the provider for the exact left lower-limb site whenever the record is vague, because a more specific code may be available.
