Are You In Network?
If you do not see your insurance provider please call our office to clarify. Insurance carrier contracts are always changing. While our office can offer you general guidance regarding insurance coverage and in-network status, it is ultimately the patient’s responsibility to ensure that any office visits, tests, procedures, medication and professional referrals are in-network and covered by your insurance plan. Services not reimbursed by the insurance plan are still the patient’s responsibility. Please review our Financial Policy.
