Starting on 1 October 2013, most individuals and small businesses will be able to shop for and enroll in health insurance coverage through their state's health insurance marketplace, also known as an exchange. The health insurance marketplaces will serve as a one-stop resource to help the uninsured and the underinsured find comprehensive health coverage that fits their needs and budget and determine whether they qualify for health insurance tax credits provided by the Patient Protection and Affordable Care Act. Physicians may benefit because insured patients are more likely to have a regular source of care, adhere to medical regimens, and access preventive care. However, implementation of the marketplaces may prove challenging if enrollment numbers are insufficient, technical problems arise, and patients are unable to access providers. Despite these potential issues, physicians are encouraged to educate themselves about how the marketplaces work so they can direct their patients to find the coverage that best meets their medical needs.
