Telephone Calls and After Hours

Please feel free to call our office, at (412) 347-0057, if you have any questions regarding your health or medications.  Our staff is very knowledgeable and available to answer questions you might have.  Please be aware that if you would like to talk to a physician, he or she may not be in the office to take your call.  In that event, you may leave a message and the doctor will return your call as soon as possible.

Our office is available 24 hours a day/365 days a year to serve your health care needs.  If you have an emergency and call after regular office hours, you will be immediately transferred to our telephone answering service.  They will then notify the doctor on call regarding your condition. If it is a routine or non-emergency call, a message will be taken or you will be asked to call back the next day during regular office hours.

Prescriptions and Refills

Please check your medications before every office visit so that we may write your prescription while you are in the office.  In the event you run out of medication, please call our office between 7:30 a.m. and 4:00 p.m. (Monday through Friday). Routine prescription refills are called in by our office staff.  New prescriptions or problems with a prescription are first given to the doctor for approval.  The office staff will then call it in to the pharmacy and contact the patient, if necessary.

Medical Records

Your medical records are considered confidential and we will only send them out with your consent and signed Authorization for Release of Medical Records form. In the event we refer a patient to another physician, we will send the patient's medical records to that physician.  We will send medical records to other doctors only upon the patient's written request.  All others, i.e., attorneys requesting medical records, will be charged a retrieval fee and a photocopying charge.

Test Results

All test results are first given to the doctor to review.  If the results are abnormal, the physician will contact the patient or request a member of our office staff to do so per the doctor's instructions.  Normal test results will be discussed with the patient at the next office visit or given to the patient over the telephone if they wish to contact our office.

Insurance and Payment

Pittsburgh Infectious Diseases, Ltd. accepts most major insurance plans.  Our experienced staff can answer most of your insurance-related questions.  We ask that you bring all your insurance cards and/or information with you at the time of your appointment and be sure to notify us if your insurance coverage has changed. 

All co-payments are due at the time of the office visit.  If the patient is a self-pay or if insurance does not cover the office visit, please bring payment at the time of service.  However, patient payment plans are available, if necessary, and may be arranged with the office staff.

Please be sure to bring your insurance card, insurance referral form, if necessary, and any completed new patient forms with you to our office.  Please arrive early to your first appointment to allow time to complete your medical history and demographic forms.
