In some areas, physicians who make a frequent habit of being asked as a second opinion, list themselves as such in the Yellow Pages of the telephone book. Ask if the physician is certified by the American Board of Medical Specialties. Competent physicians are not insulted when patients ask for a second opinion. Nevertheless, be tactful. Remember that physicians are human too.
Consultation is a time honored part of practicing medicine.
It is valuable to have two medical professionals view the same condition and arrive at independent diagnostic impressions and evaluations of treatments. Many insurance companies require a confirming opinion before some elective surgical procedures. Sometimes Medicare and Medicaid also require a second opinion. Even if a second opinion confirms the original opinion, there is often added value. It may give you more confidence in the options available.
