D6240: Bridge replacement tooth, porcelain fused to high noble metal
The false tooth (pontic) in the middle of a bridge, porcelain over high noble metal. The supporting crowns are billed separately.
Billing notes
- The missing tooth clause can rule out the whole bridge.
- Plans often replace a bridge at most once every 5 to 7 years.
For how plans pay this kind of service, typical limits and what to check before quoting, read the bridges billing guide.
This is how plans usually handle this code, not how every plan does. The patient's own plan documents and the insurer decide what's paid.
