My insurer (Anthem Blue Cross) will give me prices if I give them a procedure code and a billing zip code. Getting the procedure code and a billing zip code is another story though. When I call hospitals and doctor offices they often have no clue and will refer me to their billing department who then claims they need more information in order to know what procedure code and billing zip they'll be needing. Call back the hospital and doctor office to get the information that the billing office says they need and 'round and 'round we go. It's very frustrating.
