What is a “covered” service?
A “covered” service is one that is listed in the contract between the doctor or hospital and the insurance company. The contract specifies the agreed upon charge for each service covered by the contract. If the service is not listed on the contract, the doctor or hospital is free to charge any amount they wish. Being covered limits the amount that can be charged for a service.
For example, during an office visit, the doctor orders a chest X-ray. The clinic sends a bill for $127 for the chest X-ray. Because X-rays are a “covered” service, you are obligated to pay only the negotiated rate of $13. You are not responsible for the $114 difference.
