Reimbursement risks with radiologist extenders: there is no free lunch!

There is great allure in the concept of using qualified health care providers to assist radiologists and radiation oncologists, increasing efficiency and possibly even improving patient care delivery. However, physician services are most commonly reimbursed under a system that is resource based, and the physician work and practice expense components of reimbursement for existing procedure codes are periodically reexamined to ensure their appropriate rank in this "relative value system." Also, as new codes are developed, demonstrable physician work and practice expenses will determine the relative values for the new procedures. In both cases, the type of individual who actually performs different portions of a procedure will determine the reimbursement level. In addition, the total reimbursement must be appropriately apportioned between the physician involved and the facility where the service is delivered. This article examines some of the potential impacts on procedure coding and radiologist and radiation oncologist reimbursement schedules if physician extenders perform work previously performed by physicians. It also examines possible shifts in reimbursement from physician to facility if an extender is employed by a facility.
