Hi Ya Sean !!
You may want to give you insurance company a call and ask them if the cover the surgery and what are the qualifcations for approval. Also give the doctors office that does the surgery and find out what you need to do.. Explain to them that you aren't seeing a doctor at this time. They may have a doctor they know of that gives referrals for this surgery.
Just in case you need a referral from a Primary. You might have to bite the bullet and began seeing a regular doctor.
Good luck with your journey
