Endoscopic Repair of Spinal Fluid Leak

Maryland rates for HCPCS 31290

Seals a leak of cerebrospinal fluid, the clear fluid that cushions the brain, where it escapes through a small defect at the base of the skull and drains into the nose. Working through the nostrils with a thin lighted telescope, the surgeon closes the defect with tissue or a graft, avoiding an open incision on the head or face.
