Benefits A-Z

Laboratory and X-ray Services

Laboratory and x-ray services are covered benefits. If these services are performed by the office visit provider on a date different from the office visit or performed by a different provider such as an independent laboratory or radiology facility (even if performed on the same day as the related office visit) the beneficiary will owe a separate copayment. However, no copayment applies when provided as preventive services.
