Can I get a rhinoplasty to improve the hump on my nose and my airflow?

Thank you for your question! A septorhinoplasty can be covered through insurance, and in this operation an approach is taken to alter the cartilage/bone of the nose along with the septum to improve the functionality (i.e., breathing ability) of the nose. At the same time a cosmetic alteration to address the nasal hump can be performed, but this part is not covered by insurance. Your surgeon should be able to separate these for billing while performing both in the same operation. Hope that helps!

You seemed to be well versed in the medical criteria needed to get your insurance to cover the procedure - at least part of it. It’s helpful to think of a septorhinoplasty as being 2 surgeries - a functional one to correct your breathing which may include a septoplasty (“straightening the septum”), turbinectomies and strengthening weak airways with cartilage (such as with spreader grafts) and a cosmetic one.
Whether or not your insurance will cover the functional component of your procedure, surgery to address your aesthetic goals and correcting your breathing problem is certainly a possibility. it seems you have already seen a specialist who is able to determine you have only 11% airflow, but if you for some reason you are unable to have them perform your surgery, make sure you see a board-certified plastic surgeon for further information to best weigh your options on how to proceed.
