First Assistant in Surgery

Louisiana Medicaid will reimburse for only one first assistant in surgery. Ideally, the first assistant to the surgeon should be a qualified physician. However, in those situations when a physician does not serve as the first assistant; qualified, enrolled, advanced practice registered nurses and physician assistants may function in the role of a surgical first assistant and submit claims for their services under their Medicaid provider number. The reimbursement of claims for more than one first assistant is subject to recoupment.

request by authorized representatives of the Medicaid program.

• Immunizations and KIDMED medical, vision, and hearing screens are reimbursed at 100% of the physician fee on file. All other payable procedures are reimbursed at 80% of the physician fee on file.

• Qualified CNS/CNPs who perform as first assistant in surgery should use the “AS” modifier to identify these services.
