Will provincial coverage (MSI) cover nose job if its effecting breathing?

hello thank you for your question and provided information as well. based in you question its recommend get a consultation in personal with your doctor and discuss all about theme.

Hello and thank you for your question.  The
best advice you can receive is from an in-person consultation.  If you have a deviated septum and breathing problems, then most insurance providers will cover the septoplasty portion of your surgery.  This decision should
be based on a detailed discussion with equal input from both you
and your surgeon.   Make sure you specifically look
at before and after pictures of real patients who have had this surgery
performed by your surgeon and evaluate their results.   The most
important aspect is to find a surgeon you are comfortable with. I recommend
that you seek consultation with a qualified board-certified plastic surgeon who
can evaluate you in person.
Best wishes and good luck.

All insurance companies will cover breathing difficulties to be treated by septoplasty and turbinate ablation depending upon what is the cause.

However, Rhinoplasty is reshaping or the nose that is a cosmetic surgery procedure and can not be covered under insurance.
