Benign neoplasm of short bones of unspecified lower limb

This code signifies the presence of a non-cancerous tumor originating in the short bones of an unspecified lower limb. These benign growths are typically slow-growing and do not metastasize, but can cause pain, swelling, or functional impairment depending on their size and location.

Use this code when diagnostic imaging (e.g., X-ray, MRI) confirms a benign neoplasm within a short bone of the foot or ankle, and the specific laterality (right or left) is not documented. Documentation should clearly state "benign neoplasm" and specify a short bone of the lower limb without further anatomical precision.

• Do not use this code if the laterality (right or left) of the affected lower limb is specified; instead, use the more specific D16.31 or D16.32.
• Ensure the documentation explicitly states "benign neoplasm" to differentiate from malignant or uncertain behavior.
• This code is appropriate when the specific short bone (e.g., tarsal, metatarsal, phalanx) is not identified, but the general location within the lower limb's short bones is confirmed.
