Our office accepts most major insurance plans, including Medicare, however we always recommend that you call your insurance company to verify that we are in network and find out if they require you to get a referral from your primary care physician (if you have an HMO plan, you will probably need a referral).

Our office does not accept Medicaid (also known as Missouri Health Net, Allwell, or UHC Community Plan) or any other state-assisted medical plans.

Worker's Compensation
Our office does accept some worker’s compensation cases with the approval of your worker’s compensation carrier. Not all carriers will approve your choice of physician, so it is very important that you contact your carrier before calling our office for an appointment. Please see the Worker’s Compensation tab for more info.

Third Party Billing
Our office accepts some third party billing (the most common of which comes from an auto accident) on a case by case basis.
If your case is approved to be seen, there will be an up-front $250 deposit due at the time of your visit.
Please click here to see the Liability Policy for more information.
This form will need to be filled out and payment will need to be rendered at the time of service.

Office charges and Copays
Copays must be paid at the time of visit. If you do not have your copay, you may be asked to reschedule.
For your convenience, we accept most major credit cards, cash and personal checks (be advised there is a $30 fee for any returned checks).
After your visit, any billing questions will be referred to our billing office.
