ICD-10 Code D16.2 – Benign neoplasm of long bones of lower limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D16.2 – Benign neoplasm of long bones of lower limb
What it is
This code identifies a noncancerous tumor arising in a long bone of the lower limb, such as the femur, tibia, or fibula. It indicates benign bone growth without malignant behavior.
Clinical signs
Clinical features vary; refer to documentation. Patients may have localized pain, swelling, or an incidental imaging finding of a well-defined bone lesion. Diagnosis is usually based on imaging and, when performed, pathology.
When to use this code
Use D16.2 when the provider documents a benign neoplasm specifically involving a long bone in the lower extremity. This includes confirmed benign bone tumors of the femur, tibia, or fibula. If the record only says “bone lesion” or “mass,” check documentation before coding.
Do not use for
Do not use this code for malignant bone tumors, metastatic disease, or unspecified neoplasms. It also does not fit lesions in short bones, spine, or upper limb bones.
Coding tip
Confirm both benign behavior and the lower-limb long bone site before assigning D16.2.
