ICD-10 Code D16.31 – Benign neoplasm of short bones of right lower limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D16.31 – Benign neoplasm of short bones of right lower limb
What it is
This code identifies a noncancerous tumor arising in the short bones of the right lower limb. Use it when documentation specifies a benign neoplasm in the right foot or toe bones, not a malignant or uncertain lesion.
Clinical signs
Clinical features vary; refer to documentation. Benign bone tumors may be found on imaging or after evaluation of localized pain, swelling, or a palpable mass in the right lower limb.
When to use this code
Use D16.31 when the provider documents a benign neoplasm involving the short bones on the right side, such as a lesion in a toe or other small bone of the right lower extremity. Code it from the final diagnosis, imaging impression, or pathology report when the site is clearly stated.
Do not use for
Do not use this code for malignant bone tumors, metastatic disease, or lesions described as uncertain or unspecified. If the record does not confirm the right side or the short-bone location, check documentation.
Coding tip
Verify laterality and exact bone site before assigning the code, because D16.31 is specific to the right lower limb.
