Benign neoplasm of pelvic bones, sacrum, and coccyx

This code signifies the presence of a non-cancerous tumor originating in the bones of the pelvis, sacrum, or coccyx. These are typically slow-growing lesions that do not metastasize to other parts of the body.

Apply this code when documentation clearly identifies a benign neoplasm affecting the pelvic bones, sacrum, or coccyx, often discovered incidentally on imaging or during workup for localized pain. Supporting documentation would include pathology reports confirming benignity or imaging reports describing a characteristic benign lesion.

• Ensure the documentation explicitly states "benign" to differentiate from malignant or uncertain neoplasms.
• Verify the specific anatomical site within the pelvic region to avoid miscoding with benign neoplasms of other bone sites.
• Do not use this code for metastatic lesions to these areas; those would be coded as secondary malignancies.
