Sherry, I am also supposed to have surgery at BTC-PA, and I have Empire BC/BS. I was also told that the local BC/BS didn't approve the site because they didn't have their medicare credentials. Would you please let me know if you hear any updates. I was approved for surgery, but not for the site, until they've done those 25. If you check out my profile, you'll see we share the same frustration! Please feel free to e-mail me privately at revzwife1122@aol.com. God Bless.
