Surgery for deviated nasal septum-does it count as cosmetic if they do nose reduction also?

No: It counts as nasal septum repair with cosmetic reduction of the nose. You'll be responsible for the percentage of cost deemed cosmetic by your insurance company.

Cosmetic nose : A nose reduction is usually cosmetic even if you are doing surgery to correct a deviated septum. In cases where insurance is paying for the septoplasty, they surgery is often split where the insurance will pay for the reconstructive portion and the patient is responsible to cover the difference for the cosmetic nose reduction part of the procedure.

Partially: The septoplasty is functional, while things done to change your appearance, like rhinoplasty are cosmetic. They are commonly done together.
