Citi Benefits Handbook
Medical necessity is the treatment of dental diseases, such as dental decay and periodontal (gum) diseases. Dental services must be performed by a dentist licensed to practice in the state or by a legally qualified physician. A dentist is a doctor of dental surgery or a doctor of medical dentistry.
The Plan Administrator, acting through the Claims Administrator, reserves the right to determine whether, in its judgment, a service or supply is medically necessary or payable under this Plan. The fact that a dentist has prescribed, ordered, recommended or approved a service or supply does not, in itself, make it medically necessary.
