Are the anchor crowns on a bridge covered by insurance?
Usually yes, as a major service at around 50%, and each one is billed as its own crown. A bridge anchor crown (code D6750, porcelain over a precious metal base) is the crown cemented onto a natural tooth next to the gap so the bridge has something to hold on to. Plans treat it like any crown on that tooth, clock included.
50%
Major, counts as a crown on that tooth
2 per bridge
Most bridges have two anchor crowns, one each side of the gap, each with its own tooth number and claim line. Bill them as one and the claim bounces.
5 to 10 year clock
A regular crown (D2750) on that tooth inside the window blocks the retainer, and a blocked retainer can sink the whole bridge claim.
Healthy tooth test
Some plans only pay for a retainer crown if the anchor tooth needed a crown anyway. X-rays showing decay or a big old filling carry the claim.
Half the max, fast
Two retainers plus a pontic at 50% usually spends the whole annual maximum. The check shows what is left so you can quote the real out-of-pocket before the estimate.

- The tooth is natural, not an implant post
Documentation payers expect

Why bridge anchor crowns get denied
What happens after the anchor crowns
The two retainers plus the pontic (D6240) land in one plan year, and at 50% they usually use every dollar of the annual maximum. Anything else that patient needs, a filling (D2392) or a crown on another tooth, waits until the next plan year. The anchor teeth now carry a crown date in the plan's history, so a new crown on either one is usually not payable again for 5 to 10 years. Pulling the remaining maximum before the estimate is how the desk says all of that calmly, once.
D6750, quick answers
Does insurance cover the crowns that hold a bridge?
Most plans cover D6750 retainer crowns as major work at around 50%, one claim line per anchor tooth, after the deductible.
Does a retainer crown count against the crown frequency?
Yes. It goes into that tooth's crown history, so a crown paid in the last 5 to 10 years on the same tooth usually blocks it.
Will the plan pay to crown a healthy anchor tooth?
Not always. Some plans require the anchor tooth to need a crown on its own, so X-rays showing decay or a large old filling matter.
What if the plan denies the pontic under the missing tooth clause?
Some plans then deny the retainers too. Others pay the retainers as crowns if each tooth qualifies on its own. Ask that question before treatment.
How should a three-unit bridge be billed?
Three lines: D6750 on each anchor tooth number and D6240 for the gap. One lump line for the bridge gets returned.
