December 2016 Texas Medicaid Provider Procedures Manual

Medical and Nursing Specialists, Physicians, and Physician Assistants Handbook : 9 Physician : 9.2 Services, Benefits, Limitations, and Prior Authorization : 9.2.69 Surgery Billing Guidelines : Assistant Surgeon
Assistant surgeons may be reimbursed 16 percent of the TMRM fee for the surgical procedures performed.
Medicaid follows the TEFRA regulations for assistant surgeons in teaching hospitals. TEFRA states that an assistant surgeon will not be paid in a hospital classified by Medicare as a teaching facility with an approved graduate training program in the performing physician’s specialty. Medicaid may consider reimbursement for an assistant surgeon at a teaching hospital classified by Medicare as a teaching facility with approved graduate training program if one of the following situations is present and documented on the claim:
The primary surgeon has a policy of never, without exception, involving a resident in the preoperative, operative, or postoperative care of a patient (modifiers 80 and KX).
Use of these modifiers is not required but expedites claims processing. Therefore, it is recommended that these modifiers be used in conjunction with the procedure code rather than a narrative statement when these specific circumstances exist.
All claims for assistant surgeon services must include in Block 32 of the CMS-1500 paper claim form the name, address, and provider identifier of the hospital in which the surgery was performed. If the physician seeks an exception to this TEFRA regulation based on unavailability of a qualified resident, the following certification statement must appear on or attached to the claim form:
“I understand that section 1842(b)(6)(D) of the Social Security Act generally prohibits reasonable charge payment for the services of assistants at surgery in teaching hospitals when qualified residents are available to furnish such services. I certify that the services for which payment is claimed were medically necessary, and that no qualified residents were available to perform the services. I further understand that these services are subject to postpayment review by TMHP.”
Surgical procedures that do not ordinarily require the services of an assistant, as identified by Medicare, are denied when billed as an assistant surgery. One assistant surgeon is reimbursed for surgical procedures when appropriate.
Use modifier AS when the physician assistant is not enrolled as an individual provider and provides assistance at surgery. The claim must include the PA’s name and license number. Only procedures currently allowed for assistant surgeons are payable.
PAs actively enrolled as a Medicaid provider with an assigned provider identifier may bill assistant surgery services on a separate claim form using the PA’s individual provider identifier and modifiers U7 and 80.
