How do I find an in-network ancillary provider?

To get the most from your Horizon Blue Cross Blue Shield benefits, you should use in-network ancillary providers, as well as in-network doctors, hospitals and other health care professionals. Using in-network providers will minimize the amount you have to pay for health care.

Important information about out-of-state labs

Your health plan covers laboratory services at the in-network level of benefits when the services are provided by a lab that participates with the Blue Cross and/or Blue Shield plan in the state where the referring doctor is located. For example, if you see a doctor in New York who orders laboratory services for you, you must use a lab that participates with the Blue plan in New York to access your in-network benefits.

Blue plans across the country have educated their participating providers on how to help you maximize your benefits by using in-network providers.
