ICD-10 Code D16.3 – Benign neoplasm of short bones of lower limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D16.3 – Benign neoplasm of short bones of lower limb
What it is
D16.3 identifies a noncancerous tumor arising in the short bones of the lower limb, such as the foot bones. It indicates a benign bone neoplasm, not a malignant bone tumor.
Clinical signs
Findings may include a localized bony mass, pain, swelling, or an incidental imaging abnormality. Clinical features vary; refer to documentation.
When to use this code
Use D16.3 when the provider documents a benign neoplasm in a short bone of the lower limb and the site is specified. It is appropriate for confirmed benign bone tumors of the foot or other short lower-limb bones. If the record only says “bone tumor” or the location is unclear, check documentation before coding.
Do not use for
Do not use this code for malignant bone neoplasms, metastases, or unspecified bone lesions. Also avoid it when the lesion is in a long bone, skull, or another site outside the short bones of the lower limb.
Coding tip
Verify both benign behavior and exact anatomic site in the provider note or pathology report before assigning D16.3.
