Billing and Insurance

Paying for Treatment

Our staff is trained to help you anticipate and plan for payment of services. The patient ultimately holds full responsibility for ensuring that payment is made. We will help you navigate the steps in the process as easy as possible. Please bring all of your insurance cards and a photo ID to each and every appointment.

If your insurance is of the "managed care" type (POS, PPO, or HMO), check with your insurance company for any special instructions or pre-approvals that may be necessary for them to pay for your treatments at Lompoc Health. It is important for you to do some of this advance work before you arrive for consultation and/or treatment. Each insurer has different rules and regulations.
