D6100 is the CDT code for surgically removing a failed or failing implant body from the bone, also called explantation.
- When to use: The implant cannot be saved because it never integrated, lost its bone to peri-implant disease, fractured, or sits in a position that cannot be restored.
- When not to use: Retrieving a broken screw is D6096, treating a peri-implant defect to keep the implant is D6101 or D6102, and a socket graft goes on its own D7953 line.
- Billing note: D6100 is a by-report code, so send a narrative with the site, the reason the implant failed, and a radiograph on the first claim.
What D6100 covers
D6100 reports the surgical removal of a dental implant body: the explantation of a fixture that has failed or is failing. The whole implant comes out of the bone, whether it never integrated, lost its supporting bone to peri-implant disease, fractured, or is positioned in a way that cannot be restored. The code is by report, so the claim must include a narrative explaining why the implant was removed.
It does not cover:
- Removing a broken implant retaining screw while the fixture stays in place. That is D6096.
- Surgical debridement of a peri-implant defect to save a single implant. That is D6101.
- Debridement with osseous contouring of a peri-implant defect. That is D6102.
- A bone graft to repair a peri-implant defect around an implant that is staying. That is D6103.
- A ridge-preservation graft placed in the socket after the implant is out. That is D7953, billed on its own line.
- Extraction of a natural tooth, which uses an extraction code, not an implant code.
The distinguishing axis: removing the fixture, not treating it or its screw
D6100 miscodes come from confusing removal with the procedures that stop short of it. Each neighbor keeps the fixture in the mouth:
- D6096 retrieves a broken retaining screw. The implant stays, and once the screw is out the prosthesis goes back on.
- D6101 and D6102 treat a peri-implant defect around a single implant, cleaning the exposed surface and, in D6102, recontouring the bone.
- D6103 grafts bone to repair a peri-implant defect around an implant that is staying.
If the plan is to save the implant, the code is a peri-implant treatment code. If the fixture is taken out, it is D6100. Label these codes in your system by what they do (remove the fixture, remove a broken screw, treat a peri-implant defect) so a removal is not posted as screw retrieval or the reverse.
The by-report narrative
A D6100 claim without a narrative gives the carrier nothing to evaluate, and it is the most common reason these claims stall. The narrative names:
- The implant site, by tooth number or arch position.
- Why the implant failed, in clinical terms: failure to integrate, peri-implantitis with bone loss, fixture fracture, or a position that cannot be restored.
- The findings and technique, including mobility, bone loss, or infection observed, and how the fixture was removed.
Attach a pre-op radiograph of the failed implant, and an intraoral photo where it adds to the picture. Flag D6100 as by report in the practice management system so it cannot be sent without a narrative, and keep a reusable template covering the elements above.
Top reasons D6100 gets denied or downgraded
- No narrative on a by-report code. Without a report naming the site, the failure, and the findings, the carrier cannot adjudicate and the claim stalls or denies for insufficient information.
- Implant-service exclusion. Plans that exclude implant services often exclude the removal too, and it denies as non-covered.
- Coded as D6096 or a peri-implant code. The claim reports screw removal or peri-implant treatment when the fixture was explanted, or the reverse. The carrier pays the code the operative record supports.
- Socket graft bundled into the removal. The D7953 graft was lumped onto the D6100 line instead of billed separately, and the graft denies.
- Missing documentation of failure. No radiograph or photo showing the failed implant, so the carrier cannot judge whether removal was necessary.
Documentation that supports the claim
The claim needs the implant site, the date of the surgical removal, the narrative, and the pre-op radiograph.
For the patient record, document:
- The original implant placement date and manufacturer, if known.
- The clinical reason for failure (no integration, peri-implant bone loss, fracture, malposition).
- The removal technique and any complications.
- Whether the socket was grafted, and if so, that the graft is a separate D7953 procedure.
Example case
A patient has a lower molar implant placed two years ago that now shows mobility and advanced bone loss on the radiograph, with a history of peri-implant infection that did not respond to earlier treatment. The fixture is removed, and the socket is grafted at the same visit to preserve the ridge for a possible future implant.
Billing steps:
- Verify the plan’s implant-service benefit and confirm whether removal is covered before scheduling.
- Remove the implant body and document the site, the mobility and bone loss, and the removal technique.
- Submit D6100 with a narrative naming the failed lower molar implant, the peri-implant bone loss, and the findings, and attach the radiograph.
- Submit the socket graft under D7953 on the same date, with its own documentation.
- Post the EOB. If the plan excludes implant services, bill the patient the fee the pre-treatment estimate flagged.
FAQs
- What is the dental code for removing a dental implant?
- D6100, surgical removal of the implant body. It reports taking a failed or failing fixture out of the bone, and it is a by-report code, so the claim needs a narrative explaining why the implant had to come out. Removing only a broken screw is D6096, and treating a failing implant to save it is D6101 or D6102.
- What is the difference between D6100 and D6096?
- What comes out. D6100 removes the entire implant body from the bone. D6096 removes only a broken retaining screw while the fixture stays in place and in service, so the prosthesis can be reattached to a sound implant. The two should never be swapped.
- What is the difference between D6100 and D6101 or D6102?
- Removing the implant versus treating it to keep it. D6100 takes the fixture out. D6101 is surgical debridement of a peri-implant defect around a single implant with cleaning of the exposed implant surface, and D6102 adds osseous contouring of that defect. D6101 and D6102 try to save a failing implant; D6100 is the decision that it cannot be saved.
- Does D6100 include the bone graft after removal?
- No. A graft placed in the socket after the implant comes out, to preserve the ridge for a future implant, is reported separately under D7953. Bundling it into the D6100 line gets the graft denied. Bill each on its own line with its own documentation.
- Does insurance pay for D6100?
- It depends on the plan, and it is by report. The narrative has to name the site, the reason the implant failed, and the clinical findings. Coverage often tracks whether the plan covers implant services at all, and some plans that exclude implants also exclude their removal. Verify the benefit and send the narrative on the first claim.
