Does the policy cover corrective jaw surgery, also known as orthognathic surgery?

The shortfall on orthognathic surgery (surgery to correct conditions of the jaw and face) will be covered, provided:
• The surgery was not treated as an elective/cosmetic procedure by the medical scheme and was covered and paid by the medical scheme from the Major Medical Benefit (MMB).
• The in-hospital treatment is not subject to the 12-month preexisting condition exclusions within the first 12 months of cover.
No consumables, medicines, materials, appliances, equipment, and dental implants are covered by the Gap policy as this is not a doctor’s service charge for performing the procedure.
