Description

Identifies the presence of distant metastatic involvement of bone at time of diagnosis.



Rationale

The presence of metastatic bone disease at diagnosis is an independent prognostic indicator, and it is used by Collaborative Staging to derive TNM-M codes and SEER Summary Stage codes for some sites.




  Codes (See the most current version of the Collaborative Stage Data Collection System (http://cancerstaging.org), for rules and site-specific codes and coding structures.) 




  Note: This includes only the bone, not the bone marrow.
