Benign neoplasm of bone and articular cartilage, unspecified

This code signifies the presence of a non-malignant tumor originating from bone tissue or articular cartilage, where the specific anatomical location of the neoplasm is not documented. It indicates a benign growth that does not metastasize and is typically slow-growing.

Utilize this code when a benign bone or cartilage neoplasm is diagnosed, but the medical record lacks sufficient detail to specify the exact site (e.g., femur, tibia, spine). Documentation supporting its use would include pathology reports confirming benignity and imaging studies identifying a bone or cartilage lesion without further anatomical specificity.

• Avoid using this code if the specific anatomical site of the benign neoplasm is documented; instead, use a more precise D16.x subcategory.
• Ensure the pathology report explicitly states "benign" to differentiate from malignant bone neoplasms (C40-C41 series).
• Do not use for benign neoplasms of connective and other soft tissue (D21.-) or benign cartilaginous neoplasms of larynx, bronchus, or trachea (D14.1, D14.2).
