Reportability/Histology--Heme and Lymphoid Neoplasms: Is "the differential diagnoses include, but not limited to, mantle cell lymphoma, atypical chronic lymphocytic leukemia/small lymphocytic lymphoma and a variant of marginal zone lymphoma" reportable? In the Heme manual, they use differential diagnosis that include reportable conditions as reportable. This can be found under Code 1: positive histology in the Diagnostic Confirmation Coding Instruction section page 18. The phrase "include, but not limited to" makes this not clear.
