Download the Multiple Primary and Histology Coding Rules Manual
Revised August 24, 2012 (details]

The Multiple Primary and Histology Coding Rules are available in three formats: flowchart, matrix and text. The different formats were developed to meet the needs of different learning styles. The rules are identical in each of the three formats. Using all three formats is not recommended. It is best to choose one format. Do not combine old rules with the new.

The MP/H Rules manual is available in PDF format and may be downloaded below as a single file or by section.
