Insurance coverage varies by plan and location, and providers also vary as to whether or not they bill insurance. Please contact your healthcare provider's office directly if you're not sure whether your provider is in-network, or what your responsibility will be for this service. They can tell you about their office policies, what your insurance covers, what the co-pay may be and more.
