My ENT surgeon assisted an neurosurgeon with a transphenoidal resection of a macroadenoma. My surgeon performed the endoscopic approach to the tumor allowing access throught the spenoid sinus and then the neurosurgeon removed the tumor. How do I bill for my ENT's work. In one surgery my ENT performed a septoplasty , turbinate reduction and removal of a concha bullosa to allow access to the tumor. He removed the anterior sphenoid wall and removed the posterior 1/2 of the septum for the neurosurgeon. After the neurosurgeon was done my surgeon packed the sphenoid sinus and raised to nasoseptal flpas to close the defect.
Is this all included in assisting the neurosurgeon or how do I bill for these other procedures.
