- Lying down asleep, the space behind the tongue can narrow
- A custom device is made to seat over the upper and lower teeth
- It holds the lower jaw a little further forward
- That gives the airway more room, so breathing stays quiet
- It is made after a sleep study, worn nightly, and adjusted over time
Who usually does it
general dentist. Made by general dentists with sleep training; medical insurance, not dental, often covers it.
One question worth asking
Will this be billed to my medical plan or my dental plan?
Adjusting a sleep apnea appliance
D9948. A small adjustment to the fit or jaw position.
A custom device worn at night that holds the lower jaw slightly forward to keep the airway open. Usually made after a sleep study from a doctor. Codes cover the device, adjusting it, and repairing it.
The device holds the lower jaw slightly forward through the night so the airway stays open, and it is normally made only after a sleep study and a diagnosis from a doctor. Fitting takes several visits as the jaw position is moved a little at a time. Medical insurance rather than dental often handles these, so ask which plan the office will bill.
