Emergencies

Our office provides 24-hour coverage for emergencies. If you have an emergency that arises during the day, please call our office immediately. Please provide your name and a description of the emergency. If an emergency arises at night or during the weekend, please call our office number and the physician on-call will be contacted. You can reach our office by calling 484-526-6545. If you believe any delay in medical attention could result in a life-threatening situation, please go immediately to the nearest emergency room for treatment and notify our office as soon as you are able.

 

Insurances/Referrals

As your gastroenterology specialty practice, we will coordinate your specialty care in this area. We will refer you to another specialist for treatment when medically necessary and continue to coordinate your specialty care with the consulting doctor. We require two business days for referrals.

If your insurance plan requires a prior written referral to see a specialist, you will be responsible for all fees if you access specialty care without the referral.

We are not able to issue retroactive referrals for care already rendered. If you have any questions regarding referrals, please call our office and we will be happy to help you.

Our office accepts most major insurance plans. Please check with our office for the list of plans in which we participate. Co-payments are not billable and therefore are due at the time of the office visit. Payments are accepted in cash, personal check, Visa, MasterCard or Discover Card.
