Steps to Prepare for Clinic Visit at Boston Children's Hospital

Please call your insurance to make sure the virtual or in person visit is covered and find out how much you will be liable to pay. You can provide Dr. Srivastava’s NPI number shown on his Boston Children’s Hospital profile linked below:



In addition, you will need to provide the insurance company the CPT code. Please ask the BCH team what CPT code will be used for your child’s visit. If telehealth, please also make sure that your child has telehealth benefits that would cover this visit with an out of state provider such as Dr. Sid.

Please send (via email zoe.frazier@childrens.harvard.edu or fax to 617-730-0288) the following records prior to the appointment: genetics report confirming KS, most recent neurology note, most recent genetics clinic note (if patient sees a geneticist), and any recent cognitive/ psychological testing. The most important piece of information is the genetics report. You can also feel free to send anything else you think is relevant.
