Internal Medicine - Primary Care


Health plans are constantly changing.  It is recommended that you verify with your insurance company that Dr. Myrna De Asis is "In-Network" with your plan coverage to maximize your medical health care benefits.  Some plans require that you have a designated Primary Care Physician (PCP).  Depending on your specific coverage, some plans require that you notify or pre-certify with the insurance company regarding certain procedure (lab work, x-ray, CT scan, etc), hospitalization, or annual well-care examinations.  Be informed of your specific plan guidelines, benefits, and limitations.


Some plans may require a Referral from your insurance plan prior to seeing a specialist.  This Referral can be initiated by your PCP.  To maximize benefits, it is the patient's responsibility to make sure that a valid Referral Number is placed prior to seeing a specialist for every consultation.  Otherwise, your consultation may be considered "Out of Network" or may be denied altogether.
