Open enrollment for health insurance through one of the Affordable Care Act’s new online marketplaces runs through March 31. A swell of 48 million uninsured Americans will have the opportunity to obtain health insurance, and physicians will be inundated with new patients and new pressures as they acclimate to the effects of Obamacare.

Specialists may feel pressured now more than ever to protect their relationships with primary care physicians, who will be responsible for referring this inundation of newly insured Americans. One way to protect these relationships is to require their employees to sign restrictive covenants.
