- Code information about bone metastases only (discontinuous or distant metastases to bone) identified at the time of diangosis. This field should not be coded for bone marrow involvement.
- Bone involvement may be single or multiple.
- Information about bone involvement may be clinical or pathologic.
- Code this field whether or not the patient had any preoperative systemic therapy.
- This field should be coded for all solid tumors, Kaposi sarcoma, Unknown Primary Site, and Other and Ill-Defined Sites.
- Use code 8 for Hematopoietic, reticuloendothelial, Immunopolifereative and Myeloproliferative Neoplasms, and Hodgkin and non-Hodgkin Lymphoma.
- Use code 9 when it cannot be determined from the medical record whether the patient specifically had bone metastases; for example, when CS Mets at DX is coded as carcinomatosis but bone is not specifically mentioned as a metastatic site. Also use code 9 when it is not known whether the patient had any distant metastases.
0 = None; no bone metastases
1 = Yes
8 = Not applicable
9 = Unknown whether bone is involved; Not documented in patient record
This item was first collected in 2010. Because of delays in some hospitals in implementing registry software updates, data may be incomplete for 2010 diagnoses.
