Middle Meningeal Artery Coil Embolization

Date: Oct 17, 2023

Question:

"Indication: Traumatic subdural hematoma.

Under fluoro and roadmap guidance, Prowler Select microcath advanced over Synchro Select 0.014 microwire into parietal branch of the RT MMA, distal to foramen spinosum, images obtained in biplane projections. Angiogram shows normal antegrade flow w/ no evidence of intracranial anastomosis and no opacification of RT ophthalmic artery or RT retinal blush. Tortuosity in proximal frontal branch of the RT MMA, cath not attempted due to concern for inadvertent embolization of central retinal artery. Under blank roadmap 100-300 micron Embospheres, mixed w/ contrast, injected w/ progressive occlusion of parietal branch of RT MMA. Under blank fluoro & roadmap, microcath slowly flushed w/ heparinized saline. Under fluoro guidance coils deployed into main trunk of RT MMA w/ progressive occlusion."

61626 vs. 61624? I say 61626 due to dura encasing CNS by definition and not CNS from coding description for 61626 also MMA is part of extracranial branches, so non-CNS. Do you agree?
