  • You will need an authorization from your primary care provider (PCP) before an appointment will be made with our office
  • All co-pays will be collected at every visit


If you schedule a procedure, you will have the following payment responsibilities:

  • Professional Fee – This is the doctor’s charge for performing the procedure.  Our office will notify you of your financial responsibility.  You will be responsible to pay our office your “estimated” responsibility 3 days prior to your procedure.  We do our best to determine your financial responsibility but all are “estimates” until insurance processes your claim and determines your responsibility.
  • Facility Fee –This is a fee for the facility where your procedure is performed.  You must contact the scheduled facility to discuss your financial responsibilities.  Our office does not have any facility fee information and cannot answer any questions.  All facility fees must be paid directly to the facility.
  • Outside lab or pathology fee – If biopsies are taken during your procedure, they are sent to an outside lab.  We provide them with your insurance information and they will bill for their pathology services.  Please contact the lab directly if you have questions regarding their charges.  This information should be on your statement.

Procedure Cancellation Policy

Procedures must be cancelled 3 business days before your scheduled procedure to avoid a possible cancellation fee.  There could be a $100.00 cancellation fee which must be paid before your procedure will be rescheduled.

If you have any further questions, please call our office at (940) 687-6870 and ask for billing.
