Leuk, Lymphoma Override (IF48)

Edits of the type, Diagnostic Confirmation, Histol Type, differ in use of ICD-O-2 or ICD-O-3 and check the following:

• Since lymphoma and leukemia are almost exclusively microscopic diagnoses, this edit forces review of any cases of lymphoma that have diagnostic confirmation of direct visualization or clinical, and any leukemia with a diagnostic confirmation of direct visualization.

• If histology is 9590-9717 for ICD-O-2 or 9590-9729 for ICD-O-3 (lymphoma), then Diagnostic Confirmation cannot be 6 (direct visualization) or 8 (clinical).

• If histology is 9720-9941 for ICD-O-2 or 9731-9948 for ICD-O-3 (leukemia and other), then Diagnostic Confirmation cannot be 6 (direct visualization).

In an edit of the type, Diagnostic Confirmation, Histol Type, produces an error or warning message, check that the Histology and Diagnostic Confirmation are correctly coded. Remember that positive hematologic findings and bone marrow specimens are included as histologic confirmation (code 1 in Diagnostic Confirmation) for leukemia.

Instructions for Coding

• Leave blank if the EDITS program does not generate an error message for the edits of the type Diagnostic Confirmation, Histol Type.

• Leave blank and correct any errors for the case if an item is discovered to be incorrect.

• Code 1 if review of all items in the error or warning message confirms that all are correct.
