Summary

Endovascular therapy for saccular intracranial aneurysms of the posterior cerebral circulation, and for other intracranial aneurysms whose surgical ligation and clipping would pose great technical difficulty or be medically contraindicated, is considered medically necessary. Endovascular therapy for intracranial aneurysms or pseudoaneurysms whose location and morphology would allow relatively simple surgical ligation and clipping is considered investigational. Definitive patient selection criteria for endovascular therapy for intracranial aneurysms and pseudoaneurysms have not been established.

What to do

Action · 5 steps
01Billing team: Bill endovascular therapy for intracranial aneurysms as medically necessary only when the aneurysm is a saccular aneurysm of the posterior cerebral circulation, or another aneurysm whose surgical ligation and clipping would pose great technical difficulty or be medically contraindicated.
02Treat endovascular therapy for intracranial aneurysms or pseudoaneurysms whose location and morphology would allow relatively simple surgical ligation and clipping as investigational.
03The listed codes, including CPT 37799, are medically necessary only if the procedure is performed according to the Policy section.
04BCBSMS makes no payment for services that are not documented to be Medically Necessary.
05Check the member's specific benefit plan language, because the coverage guidelines should not be used in lieu of that language.
