The online tool that IPRO developed on behalf of the New York State Department of Health (NYSDOH) to help consumers ascertain which providers participate in which health plans has been greatly expanded. It now includes information to assist more than 4.3 million individuals accessing physicians and hospital services across the state of New York. Initially rolled out last summer to support individuals covered by NYSDOH’s NY State of Health Marketplace (including Qualified Health Plans, the Essential Plan, Child Health Plus and Medicaid managed care), the look-up tool now includes information on more than 100 additional commercial insurance provider networks, and includes dental and vision provider information. The only networks not accessible via the tool are self-funded plans, which aren’t regulated by New York State. A tutorial video is available at https://info.nystateofhealth.ny.gov/LookUpTutorial. The tool was developed by IPRO’s Health Informatics Department.
