D6111 — Implant overdenture — lower (full arch)
One of the codes covering full-arch and partial-arch dentures supported by implants. D6111 is the version for the lower jaw.
There are eight codes for implant-supported denture and they are not interchangeable. This page covers this one; the implant-supported denture guide covers the treatment they all share.
Everything below is specific to this code: what it pins down, what it is worth, how a payer handles it, and which codes it is not.
The conditions built into D6111
Arch — lower. The bone is denser, but there is far less surface area to support anything removable and the nerve running through the jaw limits how aggressive surgery can be.
Counted — per arch, so treating both jaws produces two charges rather than one.
Told apart from the codes it is confused with
D6110 — Implant overdenture — upper (full arch): It is the upper-jaw version.
D6114 — Full-arch fixed implant denture, upper: It is the upper-jaw version.
D6115 — Implant/abutment-supported fixed denture, edentulous arch (mandibular): It is the same fixed full-arch prosthesis for a lower jaw with no teeth left in it.
D6116 — Implant/abutment-supported fixed denture, partially edentulous arch (maxillary): It is the upper-jaw version.
D6111 sits in a group of eight codes in total; the remainder are linked at the foot of this page. None of these are interchangeable, even though they sound as though they might be. Checking that the code on your estimate is the one that matches the planned treatment takes a minute and prevents most billing surprises.
Every code in this group
These codes describe the same broad procedure and differ in one respect each. Each has its own page with its own fee range and coverage notes.
Questions about D6111
D6111 — what is it?
D6111 is shorthand for implant overdenture, lower, full arch — the same five characters every practice and every insurer in the country uses for it.
What should I expect to pay for D6111?
Most private fees fall in $2,500–$6,000. Geography accounts for more of that spread than anything clinical.
Will my plan pay for D6111?
Yes on most policies, treated as major work at 0–50%. A waiting period on a new policy is the commonest reason it is not.
What is the difference between D6111 and D6110?
D6110 is implant overdenture, upper, full arch: it is the upper-jaw version. The rest of the procedure is the same, which is why the two get substituted for one another on estimates.
Also known as: implant denture, snap-in denture, All-on-4, full arch implants, overdenture.
