Usage

The codes in this value set designate the staging observation as either clinical, pathological, or other. In AJCC terminology, clinical staging is represented by “c” or “yc” prefix, referring to staging done before first treatment, or staging done post-therapy or post-neoadjuvant therapy but before surgery. Pathological classification, represented by “p” or “yp” prefix, is used for patients if surgery is the first definitive therapy, or after neoadjuvant therapy and planned post-neoadjuvant therapy surgery. The “Other” code is meant to include staging at the time of recurrence or progression (“r” prefix), or for cancers not previously recognized and found as an incidental finding at autopsy (“a” prefix).

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
