Frequently Asked

 
  • Every insurance plan has different rules and policies. Our primary care services, (such as examinations and consultations), and chiropractic care are subject to potential coverage with some insurance programs. If you are seeking one of these services, please contact us and our team can provide a complimentary verification of benefits to determine your out-of-pocket costs before your appointment. Unfortunately, our infusion therapies, ozone therapies, regenerative medicine, aesthetics services, and mistletoe therapy are specifically excluded from insurance coverage and are, therefore, cash services.

  • Payment options include cash, check, credit or debit card, as well as Care Credit financing, (upon approval), through Synchrony Bank. HSA and FSA funds may also be used for care that is received in our clinic.

  • Our goal is to provide the absolute best care possible for you. We are always willing to work with your current providers during the course of your care and will help you find qualified additional providers and resources if needed.
