Appointment Policies Due to COVID-19:

Please arrive 15 minutes before your scheduled appointment time.

We must complete a COVID screening questionnaire prior to your coming into the office for an in-person visit. Once we check you in over the phone, we will meet you at our office door, take your temperature, and then proceed to take you back to an exam room.

We are currently not permitting anyone except the patient to enter the office at this time due to COVID-19 restrictions.

Location: Our office is conveniently located at 70 Thomas Johnson Drive, in the Morgan Keller Corporate Center, in Frederick, Maryland.  We are located in Suite 120, which is on the first level and easily accessible.

Hours: The office is open from 8:30 am - 5:00 pm Monday - Friday. Patients are seen by scheduled appointments only.

Dr. Kossoff performs endoscopic procedures at the Frederick Surgical Center and at Frederick Memorial Hospital.

Billing and Fees: Health plan copays are due at time of service as per your plan requirements. (Be advised that none of our services are considered "global" by insurance carriers/HMO plans and a copay will be collected for every visit to the office.) We accept Visa and MasterCard, as well as personal checks and cash.

A $50.00 missed appointment fee will be charged for failure to keep a scheduled office appointment or to provide the courtesy of a 24-hour notice to cancel an appointment. Released appointments allow us to offer them to others who are waiting to be scheduled.

We contract with most insurance plans. Billing or insurance questions should be directed to Professional Account Management Service at 410-744-7267.
