Description: 
Classifies cases recorded in the database.
Registry Coding Instructions: 

Class of Case has 24 categories. Analytic cases are coded 00-22. Nonanalytic cases are coded 30-99.

Abstracting for analytic cases is to be completed within six months of the date of first contact.

Analytic Note: 

The CoC Accreditation Program does not require hospitals to abstract nonanalytic cases (30-99). Nonanalytic cases are not in the PUF data set, and are not included in the code definitions that follow.

The CoC Accreditation Program does not require Class of Case 00 cases diagnosed in 2006 or later to be staged or followed. They are included in the PUF, but PUF users may want to omit them from some forms of analysis.

Codes for Class of Case were expanded in 2010. For cases diagnosed prior to 2010, conversion of analytic cases was generally to Class of Case 00, 10 and 20; the other codes will not be well populated for earlier cases.

Only analytic Class of Case codes are included in the table below.
