Billed for tubal removal

I got my "tubes tied" in December (bilateral salpingectomy) which should have been covered as preventive under ACA. Now, I'm getting billed to my deductible and coinsurance ($2906 deductible, $1000 coinsurance). Because of course I am, even though I called insurance before to make sure everything would get covered.

Anyway, I've been going between my insurance (UnitedHealthcare) and provider (Aurora) trying to figure this out. I even brought it up to my doctor at my post-op and she was surprised to hear it.

Today, United told me the charges that aren't covered are "diagnostic", made up of the below. I sent these to my doctor and am asking for her help in figuring this out. I don't want to pay $4k for something I wasn't planning on :)

  • J1100 Injection, dexamethosone sodium phosphate, 1 mg
  • J2250 Injection, midazolam HCl, per 1 mg
  • J2405 Injection, ondansetron HCl, per 1 mg
  • J2704 Injection, propofol, 10 mg
  • J2765 Injection, metoclopramide HCl, up to 10 mg
  • J3010 Injection, fentanyl citrate, 0.1 mg
  • J7999 Compounded drug, not otherwise classified
  • J7120 Ringer's lactate infusion, up to 1,000 cc
  • Pharmacy Charges
  • Sterile Supplies
  • Anesthesia
  • Recovery room

Has anyone experienced this, and what did you do to resolve it? Would I have a legal case, and if so, what kind of lawyer should I look for (I've never used one before)? I live in WI.

Side note, I found out pre-and post-op visits for a preventive procedure are not covered. This alone was almost $1k, so folks beware.

Thank you!
