DESCRIPTION

Class of Case divides cases into two groups. Analytic cases (codes 00-22) are those that are required by CoC to be abstracted because of the program's primary responsibility in managing the cancer. Analytic cases are grouped according to the location of diagnosis and treatment. Treatment and outcome reports may be limited to analytic cases. Nonanalytic cases (codes 30-49 and 99) may be abstracted by the facility to meet central registry requirements or because of a request by the facility's cancer program. Nonanalytic cases are grouped according to the reason a patient who received care at the facility is nonanalytic, or the reason a patient who never received care at the facility may have been abstracted.

 

Class of Case reflects the facility's role in managing the cancer, whether the cancer is required to be reported by CoC, and whether the case was diagnosed after the program's Reference Date.

*Indicates Class of Case codes appropriate for abstracting cases from non-hospital sources such as physician offices, ambulatory surgery centers, freestanding pathology laboratories, radiation therapy centers. When applied to these types of facilities, the non-hospital source is the reporting facility. The codes are applied the same way as if the case were reported from a hospital.

 

By using Class of Case codes in this manner for non-hospital sources, the central cancer registry is able to retain information reflecting the facility's role in managing the cancer consistent with the way it is reported from hospitals. Using Class of Case in conjunction with Type of Reporting Source [500] which identifies the source documents used to abstract the cancer being reported, the central cancer registry has two distinct types of information to use in making consolidation decisions.

historical changes

12/04/02

Removed IR #809.

03/26/03

Codes 7 and 8 added to allowable values. Change definition of code 9. Changed IF #608 to Class_Of_Case=8 (DC Only was 9) and removed Date_DX condition. Added Transp_Endo_Hosp to IF#450. Added 4 leading zeros to hospital numbers. Pre-CP21 cases converted to Class_Of_Case 8 if Report_Source=7.

03/03/04

Updated treatment codes in IF #369 and rewrote logic in “not equal” terminology. Removed Rad_Hosp in IF #368. Removed IF #406, 407 & 408 which referred to the Procedure fields. Removed conversion instructions from SOURCE for Version 9 records. See Use Case 22.

06/11/04

Removed IF#608 as it is duplicated in Err#612 under Report_Source

02/01/06

Removed IF #652 & 606 for cases where a “no treatment” decision is made at another facility and the Class 0 facility records this.

2010

Data Changes: Length changed from 1 to 2. New codes. Changed Update logic (was Manual). Source information updated. Conversion of old codes is required. Added IF612. Removed IF 652 (Class of Case, Date of Initial RX--SEER) and 772 (CS Items, Class of Case).
