ICD-10 Code C40.02 – Malignant neoplasm of scapula and long bones of left upper limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C40.02 – Malignant neoplasm of scapula and long bones of left upper limb
What it is
C40.02 identifies a malignant tumor arising in the scapula or long bones of the left upper limb. Use it when the documentation clearly states the primary site is on the left side.
Clinical signs
Clinical features vary; refer to documentation. Common findings in bone malignancy include localized pain, swelling, and possible limitation of movement when the lesion involves the shoulder or arm.
When to use this code
Use C40.02 when the provider documents a primary malignant neoplasm of the left scapula, humerus, radius, ulna, or another long bone of the left upper limb. It also fits when imaging, pathology, or the final assessment confirms that exact anatomic site. Check documentation if the record does not specify laterality or bone location.
Do not use for
Do not use this code for benign bone tumors, metastatic disease to bone, or malignancies in the right upper limb. If the site is unspecified or outside the scapula and long bones, choose the documented code instead.
Coding tip
Verify both the side and the exact bone before assigning C40.02.
