Balance billing

Balance billing is charging a patient the difference between a dentist's full fee and what their insurance plan actually paid or allowed. For an in-network provider, this is generally prohibited by the participation contract on any covered service (the practice must write off that difference rather than collect it from the patient), which is exactly what distinguishes an in-network write-off from a genuine collectible balance.

For an out-of-network provider, the rules are different and depend heavily on the specific plan, the state, and increasingly on state-level surprise-billing laws that have expanded well beyond their original medical-emergency focus in recent years. Some states restrict balance billing more broadly than dentists expect, and dental contracts and state regulations both vary enough that this is not a place to rely on general assumptions or what a colleague in another state does.

Any billing policy that bills a patient beyond what a contract or applicable law actually permits creates real legal and contractual exposure, not just an awkward billing conversation. Check your specific plan contracts and your state's rules, or have a healthcare attorney review your billing policy, before finalizing how the practice handles any gap between fee and reimbursement.
