Question:
Reportability--Brain and CNS: Are blood vessel tumors arising in CNS sites reportable? See Discussion.
Discussion:
Previous instructions from the CDC (Cancer - Collection and Coding Clarification for CNS Tumors - NPCR) stated that non-malignant blood vessel tumors in CNS sites are reportable and should be coded to the CNS site in which they arose. SINQ 20081113 also states that a blood vessel tumor, cavernoma/cavernous hemangioma, in the brain is reportable. However, SINQ 20120034 contradicts this previous answer stating the site should be coded to C490 [blood vessel] for a blood vessel tumor (venous angioma) in the brain.
If blood vessel tumors arising in a CNS site are no longer reportable, please specify the site/histology codes for these non-reportable tumors and when this change took place.
Answer:
Vascular tumors of the CNS are reportable when they arise in the dura or parenchyma of the CNS and should be coded accordingly. The instructions in the CDC book regarding primary site coding are not the most current instructions.SEER assumed responsibility for brain and CNS reporting instructions in 2007.
The tumor in SINQ 20120034 is not reportable because it arises in a blood vessel. The cavernous hemangioma in SINQ 20081113 is reportable because the primary site is the white matter of the cerebral cortex.
