Several studies provide evidence and show overutilization of services and increased costs under the in-office ancillary services (IOAS) exception loophole to the Stark self-referral law. The exception has fostered over-ordering of anatomic pathology (AP) services by self-referring physicians to maximize profits. The IOAS exception was intended to afford patient convenience yet AP services are rarely ever done at the time of an office visit.

We have long advocated for closing the loophole and passing other laws that protect your ability to provide high-quality services in a fair competitive environment, by requiring direct billing of pathology services, or prohibiting markups of services.
