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 : 9.2.2 Substitute Physician

Physicians may bill for the service of a substitute physician who sees clients in the billing physician’s practice under either a reciprocal or locum tenens arrangement.
A reciprocal arrangement is one in which a substitute physician covers for the billing physician on an occasional basis when the billing physician is unavailable to provide services. Reciprocal arrangements are limited to a continuous period no longer than 14 days and do not have to be in writing.
A locum tenens arrangement is one in which a substitute physician assumes the practice of a billing physician for a temporary period no longer than 90 days when the billing physician is absent for reasons such as illness, pregnancy, vacation, continuing medical education, or active duty in the armed forces. The locum tenens arrangement may be extended for a continuous period of longer than 90 days if the billing physician’s absence is due to being called or ordered to active duty as a member of a reserve component of the armed forces. Locum tenens arrangements must be in writing.
The substitute physician must be enrolled in Texas Medicaid and must not be on the Texas Medicaid or HHSC Family Planning Program provider exclusion list. The billing provider’s name, address, and national provider identifier must appear in Block 33 of the claim form. The name and office or mailing address of the substitute physician must be documented on the claim in Block 19, not Block 33.
When a physician bills for a substitute physician, modifier Q5 or Q6 must follow the procedure code in Block 24D for services provided by the substitute physician. The Q5 modifier is used to indicate a reciprocal arrangement and the Q6 modifier is used to indicate a locum tenens arrangement.
When physicians in a group practice bill substitute physician services, the performing provider identifier of the physician for whom the substitute provided services must be in Block 24J.
Physicians must familiarize themselves with these requirements and document accordingly. Those services not supported by the required documentation as detailed above will be subject to recoupment.
