December 2016 Texas Medicaid Provider Procedures Manual

Medical and Nursing Specialists, Physicians, and Physician Assistants Handbook : 10 Physician Assistant : 10.4 Claims Filing and Reimbursement : 10.4.2 Reimbursement

According to 1 TAC §355.8093, the Medicaid rate for PAs is 92 percent of the rate paid to a physician (MD or DO) for the same professional service and 100 percent of the rate paid to physicians for laboratory services, X-ray services, and injections.
PA providers who are enrolled in Texas Medicaid as THSteps providers also receive 92 percent of the rate paid to a physician for THSteps services when a claim is submitted with their THSteps provider identifier as the billing provider.
PAs who bill Medicaid directly for services they perform must use their individual provider identifier. If the services were performed by the PA but billed by a physician or physician group, the billing provider is the physician or physician group. Physicians may be reimbursed 92 percent of the established reimbursement rate for services provided by a PA if the physician does not make a decision regarding the client’s care or treatment on the same date of service as the billable medical visit. This 92 percent reimbursement rate does not apply to laboratory services, X-ray services, or injections provided by a PA.
Providers can refer to the online fee lookup (OFL) or the applicable fee schedule on the TMHP website at To request a hard copy, call the TMHP Contact Center at 1-800-925-9126.
