The American Association of Orthodontists (AAO) has designated October as National Orthodontic Health Month. This month is dedicated to raising awareness about the benefits of orthodontic treatment and the importance of good oral health. Orthodontics aims at improving the appearance of the teeth, making it easier to clean the teeth and how they work by straightening or moving teeth to improve their appearance. This form of dentistry is ideal to straighten crooked teeth, close wide gaps between the teeth, improve speech or chewing ability, boost the long-term health of gums and teeth, and treat an improper bite. It mainly treats malocclusion and helps to correctly position the teeth when the mouth is closed. Left untreated, such issues can result in more serious oral health problems such as tooth decay, tooth loss, gum disease or even jaw problems.

People consider these treatments for cosmetic purposes as well as to improve oral functions. AAO has reported that more than 1.6 million adults in North America are receiving orthodontic treatment from AAO orthodontists. Medical dental devices used for this treatment include headgear, plates, braces, fixed or removable space maintainers, aligners, palatal expanders, retainers, splints and more. To assess the state of the person’s teeth, the orthodontist may carry out a clinical examination, take x-rays of the teeth and jaw and make plaster models of the teeth.

While a dentist specializes in the broader area of oral health, an orthodontist deals specifically with the bite and straightness of teeth. Experienced dental billing companies can provide the challenging medical coding task, as they are up to date with the changing coding standards and insurance guidelines. It is important to include the correct CDT, ICD, HCPCS and CPT codes on the medical claims, as any coding errors could lead to claim denials. For most insurers severe malocclusion requires prior authorization, while cleft palate requires expedited authorization (EPA).

Completing a full dental eligibility verification before the patient’s date of service is a crucial process. Before providing treatment, practices must ensure that the patient is eligible for orthodontic benefits. Some dental plans restrict benefits to children, but others provide benefits to adults. Other important steps in orthodontic billing include coordination of benefits (COB) and completion of the insurance form.
