Multiple Primaries Calculator

The Multiple Primaries Calculator was designed to be used with the coding manual. Follow the rules and workflow in the manual prior to using the calculator. Use the Multiple Primaries Calculator when the rules instruct you to do so. If you are working with cases diagnosed before 2010 use the ICD-O-3 Hematopoietic Primaries Table (PDF) instead. This calculator should only be used for cases where at least one of the diagnoses is from 2010 or forward.
