Took me 71 phone calls over 4 days to get this straightened out. The only reason it is done is because I was overly persistent! In a nutshell...no prior auth needed....then needed....then not needed....then quantity was wrong...then 21 days to review...then need more info from dr....then approval....then sorry on hold even though it was approved...then someone cancelled the order ... then they needed a new prior auth!....also NOBODY WILL RETURN YOUR CALL EVER!!!then 20 people are working on it....supposedly....if you are not PERSISTENT you will NEVER GET WHAT YOU NEED! User's recommendation: You have to be OVERLY PERSISTENT IT'S EXHAUSTING.
