specification

This edit is skipped if any of the following conditions are true:

• Histologic Type ICD-O-3 is blank

• Behavior Code ICD-O-3 is blank

• Date of Diagnosis is blank

The morphology field is defined by the International Classification of Diseases for Oncology, Third Edition (ICD-O-3) and consists of the following subfields:

• Histologic Type ICD-O-3 - 4 digits

• Behavior Code ICD-O-3 - 1 digit

1. Single Subfield Checks

Only those histology/behavior codes defined by ICD-O-3 are valid.

Histology (Histologic Type ICD-O-3)--must contain a valid ICD-O-3 code. Codes are validated at two levels. Histology codes listed with behavior codes of 2 or 3 in ICD-O-3 are considered valid whenever they appear.

Codes listed in ICD-O-3 with behavior codes (Behavior Code ICD-O-3) of only 0 or 1 are also considered valid (i.e.,"reportable"), since use of the behavior matrix of ICD-O-3 allows for the elevation of the behavior of such histologies when the neoplasm is in situ or malignant. However, this edit requires review of these cases to verify that they are indeed in situ or malignant. If the histology and behavior are correct on review, then Over-ride--Histology is to be set to 1 (or 3, if the flag is used for both this edit and SEER IF31). An internal binary table is used to represent the histologies listed in ICD-O-3 according to their listed behaviors.

Exceptions to the above rule are 8442, 8451, 8462, 8472, and 8473. These codes may have been entered in ICD-O-2 as malignant or in situ and correctly converted to ICD-O-3 as borderline (Behavior Code ICD-O-3 = 1). Such cases do not require review (that is, the Over-ride--Histology flag does not have to be set to 1 or 3).

Additional exceptions were added for all benign histologies for brain and other CNS (Primary Site = C700-C729) and intracranial glands (Primary Site = C751-C753). Another edit, "Primary Site, Morphology-Type,Beh ICDO3(SEER IF25)," verifies that site/histology/ benign behavior combination are correctly coded for these particular sites.

The code 9421 (juvenile astrocytoma), although moving from behavior code 3 in ICD-O-2 to 1 in ICD-O-3, will CONTINUE to be collected with a behavior code of 3. This edit requires that 9421 be coded with a behavior of 3 and it cannot be over-ridden.

Additional exceptions were added to accommodate the collection of benign brain tumors diagnosed on or after 01/01/2004. The following benign histologies will pass without review:

8146, 8271, 8861, 8897, 9121, 9122, 9131, 9161, 9350, 9351, 9352, 9360, 9361, 9383, 9384, 9394, 9412, 9413, 9444, 9492, 9493, 9506, 9531, 9532, 9533, 9534, 9537, 9541, 9550, 9562, 9570.

To accommodate the new Hematopoietic and Lymphoid Neoplasm Rules effective for cases diagnosed 1/1/2010 and later:

1. The following Histologic Type ICD-O-3 codes are allowed only for cases with a year of Date of Diagnosis of 2010 and later:

9597, 9688, 9712, 9724, 9725, 9726, 9735, 9737, 9738, 9759, 9806, 9807, 9808, 9809, 9811, 9812, 9813, 9814, 9815, 9816, 9817, 9818, 9865, 9869, 9898, 9911, 9965, 9966, 9967, 9971, 9991, 9992

2. The following Histologic Type ICD-O-3 codes were considered benign and/or borderline prior to 2010 and, if coded with Behavior ICD-O-3 code of 3, required an over-ride. For cases diagnosed 2010 or later, these histologies are now reportable (with Behavior ICD-O-3 code of 3) and an over-ride should not be used:

9751

9831

9975

2. Multi-Subfield Checks

The subfields are also checked for consistency among themselves. Each of these checks is defined in detail below.

Histology/Behavior:

In situ histologies: The following histologies are not accepted with a behavior code `2' (in situ):

8000-8005

8020, 8021

8331, 8332

8800-9055

9062

9082, 9083

9110-9493

9501-9992

Malignant histologies: The following histology is not accepted with a behavior code `3' (malignant):

8077

NOTE:

Over-ride Histology is also used for SEER edit IF31. Code 3 in Over-ride Histology indicates that both SEER's MORPH edit and IF31 are being over-ridden.

Additional Information:

This edit checks the validity of the ICD-O-3 histologic type subfields histology and behavior. The subfield behavior is checked in a separate edit. The specific error message will identify which part of the code is problematic or which subfields are inconsistent.

1. The edit requires review of a case in which the 4-digit morphology code is one that appears in ICD-O-3 only with behavior codes of 0 or 1. Verify the coding of morphology, and that the behavior should be coded malignant or in situ. The registrar may need to consult a pathologist or medical advisor in problem cases. If the case is correctly coded, set the Over-ride--Histology flag to 1 (or 3, if the flag is also being set for the edit Diagnostic Confirmation, Behavior Code ICDO3 (SEER IF31).

2. Histology and behavior codes are compared, and some combinations of in situ behavior and histology are not allowed. (These histologies are specified in the "Description" section of the documentation.) "In situ" is a concept that only pertains to epithelial neoplasms; therefore, an in situ behavior is not allowed with non-epithelial morphologies, such as sarcomas, leukemias, and lymphomas. In situ behavior is also disallowed for a handful of codes representing epithelial neoplasms which, by their nature, cannot be in situ.

Errors from this edit usually result from misapplication of coding rules. Correction of errors may require inspection of the abstracted text, either online or as recorded on a paper abstract. Review of the original medical record may be necessary. Review the coding of each subfield. Consult a pathologist or medical advisor when necessary.

EXAMPLE:

HISTOLOGIC TYPE 9650/3, HODGKIN LYMPHOMA

BEHAVIOR CODE 2, IN SITU

A behavior code of 2, in situ, is not correct for Hodgkin lymphoma. Change the behavior to 3, malignant.
