Functional repair surgery does not belong to the category of cosmetic surgery. For example, if the patient's finger is cut off and it is found that the finger can't do some actions before the injury, the operation that needs to be done is functional surgery. If all the movements of the fingers can be done as before the injury, but the scars left after the operation are quite ugly, then the surgery that needs to be done is the category of cosmetic surgery. You may still need to work as a doctor. Don't be more beautiful than the original conclusion, if it reflects the function, otherwise it will be reimbursed.
