lateral periodontal cyst- DENTAL and MEDICAL INSURANCE OMG

I have delta dental PPO and Aetna Medical. Need a biopsy, pathology, and potentially CT.

every oral surgeon I go to says that the biopsy, the pathology, and the CT scan are NOT COVERED and out of pocket for approx $1000 total. They said 'you can try to submit to your medical...'' blah blah blah but we all know that game.

Is there a medical in network provider who can do the biopsy removal, pathology, etc. vs an oral surgeon. The dental and medical insurance are useless for this issue.

Can you recommend an alternative? Can I go to a different type of oral surgeon for this that would be covered by my insurance?

Is there a pathology center that is in network for medical? What should I be looking up here. Surely I cannot be the only one getting screwed here.
