Provider Directory Regulations: A State-by-State Guide


Provider directories have long been a source of inaccurate provider information. As a result, federal (CMS) and state regulations will be enforced to ensure that healthcare consumers receive accurate information. Failure to comply with these specific state regulations will result in certain penalties.

Stemming from work with health plans throughout the United States, our compliance team compiled a list of regulations for each state.

No State Regulation

Where there are no state requirements, the following CMS guidelines must be followed: Provider directories must contain relevant and accurate provider information. This will be implemented through directory maintenance through monthly updates of provider information and quarterly touch points with providers within a Qualified Health Plan network.

Alabama, Alaska, Arizona, Hawaii, Illinois, Indiana, Iowa, Kansas, Kentucky, Maine, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nebraska, Nevada, New Mexico, North Dakota, Ohio, Oklahoma, Pennsylvania, Rhode Island, Utah, Virginia, West Virginia, Wyoming Must update provider directories monthly and collect up-to-date information from providers quarterly QHP & Medicare Medicaid Guidance to Verify that Networks are Adequate and Provider Directories are Current (p. 134-135)


With the recent demand for transparency in healthcare, specifically in provider data, CMS federal regulations have been put in place to promote efficiency within the healthcare system. State regulations have begun to fall in line with this nationwide agenda. Thus, it is clear that no state is free of regulations pertaining to provider directories, and most states are aligning themselves with federal regulations.
