Your claims do not all go to the same place.
Most specialties send every claim to one kind of payer. Dentistry does not. A filling, a cleaning, and a crown go to a dental plan. A sleep appliance for apnea, a trauma repair, or certain oral surgery can belong on a medical claim instead, with a completely different code set and a completely different form.
Get that call wrong and the claim usually does not just deny. It is often never reviewed as the thing it actually was, because it arrived in the wrong system entirely.
Dental plans add their own version of complexity on top of that. An annual maximum caps what a patient’s plan will pay in a year, no matter how necessary the next procedure is. Frequency limits restrict how often a cleaning or an X-ray is covered. Alternate benefit provisions let a plan pay for the cheaper of two acceptable treatments, whatever the dentist actually placed.
Then orthodontics changes the shape of billing entirely. One banding date starts a claim cycle that can run for years, with a down payment and a recurring schedule behind it, nothing like a single-visit procedure.
A billing company built for medical claims alone misses dentistry’s own rules. A billing company built for dental claims alone misses the medical claims sitting inside a dental chart. Dentistry needs both at once.
