Class of case reflects the facility's role in managing this cancer, whether the cancer is required to be reported to ACoS by approved facilities, and whether the case was diagnosed after the program's reference date. Enter the two digit code that describes the patient's relationship to the facility.

Instructions for Coding

Code 00 applies only when it is known that the patient went elsewhere for treatment. If that information is not available, code class of case '10.' It is possible that information for coding class of case will change during the patient's first course of care. If that occurs, edit the code accordingly.
ACoS approved facilities should document Institution Referred To (item #31660) for patients coded 00 to establish that the patient went elsewhere for treatment.
A staff physician (codes 10-12, 41) is a physician who is employed by the reporting facility, under contract with it, or who has routine practice privileges there.
Refer to the "Case Reporting Requirements" section of this manual for a discussion of Classes and KCR requirements.

Analytic Classes of Case
(Required by CoC to be abstracted by accredited programs)
Initial diagnosis at reporting facility or in a staff physician’s office
00	Initial diagnosis at the reporting facility AND all treatment or a decision not to treat was done elsewhere
10	Initial diagnosis at the reporting facility or in an office of a physician with admitting privileges AND part or all of first course treatment or a decision not to treat was at the reporting facility, NOS
11	Initial diagnosis in an office of a physician with admitting privileges AND part of first course treatment was done at the reporting facility
12	Initial diagnosis in an office of a physician with admitting privileges AND all first course treatment or a decision not to treat was done at the reporting facility
13	Initial diagnosis at the reporting facility AND part of first course treatment was done at the reporting facility; part of first course treatment was done elsewhere
14	Initial diagnosis at the reporting facility AND all first course treatment or a decision not to treat was done at the reporting facility
Initial diagnosis elsewhere
20	Initial diagnosis elsewhere AND all or part of first course treatment was done at the reporting facility, NOS
21	Initial diagnosis elsewhere AND part of first course treatment was done at the reporting facility; part of first course treatment was done elsewhere.
22	Initial diagnosis elsewhere AND all first course treatment or a decision not to treat was done at the reporting facility
Non-analytic Classes of Case
(Not required by CoC to be abstracted by CoC accredited programs however may be required by program’s Cancer Committee, state or regional registry, or other entity)
Patient appears in person at reporting facility
30	Initial diagnosis and all first course treatment elsewhere AND reporting facility participated in diagnostic workup (for example, consult only, treatment plan only, staging workup after initial diagnosis elsewhere)
31	Initial diagnosis and all first course treatment elsewhere AND reporting facility provided in- transit care; or hospital provided care that facilitated treatment elsewhere (for example, stent placement)
32	Diagnosis AND all first course treatment provided elsewhere AND patient presents at reporting facility with disease recurrence or persistence (active disease)
33	Diagnosis AND all first course treatment provided elsewhere AND patient presents at reporting facility with disease history only (disease not active)
34	Type of case not required by CoC to be accessioned (for example, a benign colon tumor) AND initial diagnosis AND part or all of first course treatment by reporting facility
35	Case diagnosed before the program’s Reference Date AND initial diagnosis AND all or part of first course treatment by reporting facility
36	Type of case not required by CoC to be accessioned (for example, a benign colon tumor) AND initial diagnosis elsewhere AND all or part of first course treatment by reporting facility
37	Case diagnosed before the program’s Reference Date AND initial diagnosis elsewhere AND all or part of first course treatment by facility
38	Initial diagnosis established by autopsy at the reporting facility, cancer not suspected prior to death
Patient does not appear in person at reporting facility
40	Diagnosis AND all first course treatment given at the same staff physician’s office
41	Diagnosis and all first course treatment given in two or more different offices of physicians with admitting privileges
42	Nonstaff physician or non-CoC accredited clinic or other facility, not part of reporting facility, accessioned by reporting facility for diagnosis and/or treatment by that entity (for example, hospital abstracts cases from an independent radiation facility)
43	Pathology or other lab specimens only
49	Death certificate only
99	Nonanalytic case of unknown relationship to facility (not for use by CoC accredited cancer programs for analytic cases).
