Question:

Multiple Primaries (Pre-2007)--Brain and CNS: Is neurofibromatosis a separate and distinct primary in the presence of a longstanding glioma? Does the following show one or two primaries? See Discussion.

Discussion:

MRI of Brain: 1. Findings compatible with left optic nerve glioma. 2. Stable enhancing focus in left temporal white matter. Lack of interval change since Dec 2000 suggests a white matter finding typical of neurofibromatosis and makes more aggressive processes such as astrocytoma less likely. Small aneurysm can not be excluded.

Answer:

For tumors diagnosed prior to 2007:

Neurofibromatosis and glioma would be separate brain/CNS primaries.

However, there is only one primary in the case example above: Glioma, left opic nerve. "...suggests a white matter finding typical of neurofibromatosis" is not reportable. "Suggests" is not a reportable term. Therefore, in this example neurofibromatosis is not reportable unless there is a more definitive statement in the record.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
