Cost for revision rhinoplasty, septo, and nasal valve reconstruction (which is the main reason I'm going due to poor breathing)?

I would have to see you for consultation to know for sure but revision rhinoplasty ranges around $8000-8500 depending on what has to be done. Insurance coverage is usually small so you probably won't pass your deductible. The only way to know is to come in for an insurance visit plus consultation and then your insurance company can be called.

 Without an examination, it is very difficult to give a price quote for both functional and cosmetic nasal surgery.  Functional nasal surgery is typically billed to the patient's medical insurance, once medical necessity is been documented and pre-authorization has occurred. Anticipate co-pays and deductibles associated with your medical insurance. Cosmetic surgery on the nose is typically paid for by the patient.

You would have to be seen in person to determine what might be possible.  Insurance may cover some breathing reconstruction.  Good luck.

This is impossible to answer without an examination and not knowing the details of your specific plan. Perhaps seek a second and even a third opinion before committing to a revision surgery.
