Implant Barrier Membrane Dental Code (D6107): Per Implant

Written by Tabby M. Updated for CDT 2026

D6107 is the CDT code for placing a barrier membrane that does not dissolve around a dental implant, reported once per implant rather than once per surgical site.

The unit is the implant, which changes the line count on any case where one flap covers two fixtures, and it is the detail most likely to be entered wrong in a practice management system that defaults every surgical code to a site. Underneath that sits a benefit gate that decides more claims than any documentation issue: Cigna's IMPLNT-13 guidelines allow the code only on plans that cover surgical implant placement, and Delta Dental Insurance Company lists it as not a benefit of most of its plans at all. So D6107 is often correct and unpaid at the same time, which is a very different conversation with the patient than a denial you can appeal.

What D6107 covers

D6107 reports placing a barrier membrane that does not resorb around a dental implant. The membrane covers a bony defect at the fixture, holds space, and keeps fast-growing soft tissue out while bone regenerates underneath. The descriptor names both uses, peri-implant defects and implant placement, which is the practical range: the membrane over a dehiscence or fenestration at the time the fixture goes in, and the membrane over a defect around an implant that has been in service and lost bone.

Nonresorbable means the material stays. Expanded PTFE, often titanium-reinforced when it has to hold shape over a contour, does not break down, so a later surgery retrieves it. That visit is D4286. Both codes arrived in the same CDT 2023 update, so the removal was never folded into D6107 the way it once sat inside the natural-tooth code.

The code reports the barrier only. It does not include:

  • The surgical placement of the implant body.
  • Flap entry and closure, wound debridement or osseous contouring.
  • The bone graft under the membrane, which is D6103 at an existing implant or D6104 at the time of placement.
  • Biologic materials placed to aid osseous regeneration.
  • Debridement of a peri-implant defect, which is D6101, or debridement with osseous contouring, which is D6102.
  • The removal of the membrane, which is D4286.

Per implant, not per site

Every other guided tissue regeneration code in the family is counted per site. D6106 and D6107 are counted per implant, and the difference is not cosmetic.

One surgical entry that addresses bone defects around two adjacent fixtures is two D6107 lines when the operative note documents a membrane at each implant. The same flap over a single fixture with two separate bony defects is one line, because there is one implant. Site-based thinking gets both of those wrong in opposite directions.

A single continuous sheet of PTFE laid over two implants does not reduce the count either. The unit the code names is the implant, not the piece of material, so the question the note has to answer is how many fixtures the barrier covered, not how many membranes were trimmed.

The count then has to survive the claim form, where a reviewer has only the lines and the narrative. Report each membrane on its own line with the implant’s site number in the tooth field, and name the fixtures individually in the remarks instead of describing the surgery as one regional procedure. Two D6107 lines behind a narrative that reads “guided tissue regeneration, posterior right maxilla” is the version that comes back as a request for records.

D6107 against the implant bone-graft codes

This is the boundary that decides the most claims, because the graft and the membrane happen in the same breath and get reported as one thing.

  • D6103 is the bone graft that repairs a defect around an implant already in place.
  • D6104 is the bone graft placed at the same visit as the implant.
  • D6107 is the barrier over either one, when the membrane is nonresorbable.

The graft codes are written to exclude the barrier and biologic materials and direct them to be reported separately, so a case that grafts a peri-implant defect and covers it with a PTFE membrane reports two procedures. Rolling the membrane into the graft line underreports the surgery. Reporting a membrane with no graft when material was actually placed does the same thing in reverse.

Two neighbors are easy to confuse with the graft codes and are neither graft nor membrane: D6101 is debridement of a peri-implant defect with surface cleaning of the implant, and D6102 is that debridement with osseous contouring. Those are the cleaning and reshaping procedures, not regeneration.

Back on the graft-plus-membrane pair, coding it correctly and getting it paid are two different questions. Cigna’s 2026 DPPO guidelines, policy IMPLNT-13, carry two same-site, same-date disallows on D6106 and D6107, and the second one is the reason the per-implant codes are tighter than their edentulous counterparts. The first is the familiar bone-graft rule: the membrane is not allowable alongside any other allowable bone graft procedure, which is the restriction OS-09 also applies to D7956 and D7957. The second has no OS-09 equivalent. IMPLNT-13 also disallows the membrane alongside any other peri-implant regenerative procedure at the same site on the same day, which reaches past grafting into the rest of the regenerative work done around a failing fixture. So on a Cigna DPPO the clinically standard graft-plus-membrane case loses the membrane line by policy rather than by error, and so does a case that pairs the membrane with another regenerative procedure at the same fixture on the same day. Other plans pay both lines. Confirm which one you have at verification and take financial consent before surgery, because a policy bundling rule leaves nothing to resubmit afterward.

The site family is the other half of the code

CDT 2023 rebuilt guided tissue regeneration into three site families, each with a resorbable and a nonresorbable member. The material alone never identifies the code.

  • Natural tooth: D4266 resorbable, D4267 nonresorbable, per site.
  • Implant: D6106 resorbable, D6107 nonresorbable, per implant.
  • Edentulous site, no tooth and no implant there: D7956 resorbable, D7957 nonresorbable, per site.

Carriers write the boundaries from both directions. Cigna’s IMPLNT-13 policy disallows D6106 and D6107 at an edentulous site, and its OS-09 policy disallows the edentulous codes at a site with an existing implant. Its PERIO-09 policy disallows the natural-tooth codes at the site of an existing implant and at a site with no natural tooth present. There is no overlap to argue about; a membrane belongs to exactly one family and the note has to say which.

The case that generates the most argument is the membrane placed during implant surgery. The descriptor for D6106 and D6107 names implant placement as one of the two uses, so a barrier placed as the fixture goes in is the implant family rather than the edentulous one. That is a codebook rule, not a carrier position, and Cigna’s PERIO-09 policy corroborates it from the other side by disallowing the natural-tooth codes at the same site and date of service as a surgical implant placement. A barrier placed at a ridge being built up months before any implant is placed has no fixture at the site and is the edentulous family.

The removal visit is a separate code

CDT 2023 created D6107 and D4286 in the same action, so the retrieval has never been inside this code and reporting it separately is not optional. Whether it pays is a different question, and the published carrier policies mostly turn on one administrative fact, whether your office is the one that placed the barrier; the D4286 page works through where the carriers land and what to do when the removal denies.

What that means on a D6107 case is narrow and worth doing on the day of surgery. The second appointment belongs in the treatment plan and the quote from the start, and the account should record who placed the membrane while someone still remembers, because that is the fact the removal claim will turn on months later.

Coverage reality

The implant benefit is the gate. Cigna’s IMPLNT-13 policy allows the per-implant GTR codes only for plans that cover surgical placement of implants where the implant meets plan guidelines, and disallows them outright when the plan has no implant coverage. Delta Dental Insurance Company’s CDT 2023 summary is blunter and lists D6106 and D6107 as not a benefit of most of its plans, with the fee falling to the patient. That is one carrier’s published stance on its own plans, written as patient responsibility rather than a bundling write-off, and it does not generalize. Medicaid programs prohibit balance-billing regardless of what a commercial plan allows.

Where it is covered, the criteria are measured. Cigna’s allowable conditions include documentation, meaning periodontal charting and radiographs, confirming probing depths around the implant of 5 mm or deeper with bone loss present, or use to aid tissue regeneration during implant placement. Depths under 5 mm, or charting and images that do not show bone loss, are listed as not allowable. Either one on its own is enough to disallow.

The published exclusions are clinical, not administrative. UnitedHealthcare’s dental barrier membrane policy indicates GTR alongside bone grafting for implant placement and treatment of peri-implant defects, and excludes patients with uncontrolled systemic conditions, medications that impair the healing response, poor oral hygiene, and non-compliance with previous therapy. A narrative cannot argue past those.

Documentation that supports the claim

  • The implant, identified, with the site and the fixture, so the per-implant count is verifiable and the site family is not in question.
  • The membrane, named by material and product. Nonresorbable is the single word that makes this line D6107 instead of D6106, and it is also what tells scheduling that a retrieval visit is owed on this site.
  • Periodontal charting around the implant and current radiographs, since the carriers that publish criteria measure probing depth and bone loss rather than reading the narrative.
  • The clinical context, either a peri-implant defect on a fixture in service or a dehiscence or fenestration addressed at placement.
  • The graft, separately, with the material used and whether it was D6103 or D6104, so both lines stand on their own.
  • One line per implant, with each fixture itemized when more than one was treated under the same flap.

What to get right in your PMS

The menus differ across Open Dental, Dentrix, Eaglesoft, Curve and Carestream, but the setup that prevents these denials is the same:

  1. Configure D6106 and D6107 to count per implant. They are the only members of the GTR family that do. A default of per site or per quadrant produces undercounted claims on multi-implant surgeries.
  2. Test what a two-implant case actually exports before you bill one. Systems that accept two D6107 entries on screen do not all put two lines on the claim; some collapse them into one line with a quantity of two, and some drop the duplicate. Run a two-fixture case through a test patient and read the generated claim, because this is the only place in the GTR family where that behavior changes the payment.
  3. Keep the membrane and the graft as separate line items. D6103 and D6104 are the graft. D6107 is the barrier. A blended fee-schedule entry loses one of them.
  4. Route verification to the implant benefit. These codes live or die on implant coverage, so a verification checklist that only asks about periodontal benefits will produce quotes the plan never intended to honor.
  5. Attach the removal appointment to the treatment plan. Schedule the D4286 visit when the barrier is placed, and record on the account who placed it, since that is the fact the removal claim turns on.

FAQs

What is the difference between D6107 and D6106?
The barrier material. Both report guided tissue regeneration at an implant and both are counted per implant. D6106 is the resorbable membrane, which the body absorbs on its own. D6107 is the nonresorbable membrane, which has to be surgically retrieved at a later visit. That retrieval is reported on D4286 and is usually not separately paid when your office placed the barrier. Code from the operative note rather than the treatment plan, and price the case knowing a D6107 plan carries a second appointment that a D6106 plan does not.
Is D6107 counted per implant or per site?
Per implant. That is the unit written into the code, and it is what separates it from the rest of the guided tissue regeneration family, where D4266, D4267, D7956 and D7957 are all per site. One surgical entry that treats bone defects around two adjacent fixtures generates two D6107 lines, not one, provided the operative note documents the membrane at each implant. Practice management systems that default surgical codes to a site or a quadrant will undercount this one, so check how the code is configured before the first case rather than after.
How is D6107 different from D6103 and D6104?
Those are bone graft codes and D6107 is a membrane code. D6103 is the bone graft placed to repair a defect around an existing implant. D6104 is the bone graft placed at the same visit as the implant. D6107 is the barrier that goes over graft material to keep soft tissue out while it heals. A case that grafts a peri-implant defect and covers it with a nonresorbable membrane is reporting two procedures, D6103 and D6107. The graft codes explicitly direct the barrier and any biologic materials to be reported separately, so folding the membrane into the graft line underreports the surgery.
Does D6107 apply at an edentulous site?
No. CDT 2023 split guided tissue regeneration by site family, and D6107 is scoped to an implant. An edentulous location with no implant present is D7956 or D7957, per site, and a natural tooth is D4266 or D4267. Cigna's IMPLNT-13 policy makes this explicit and disallows D6106 and D6107 when performed at an edentulous site, with its OS-09 policy disallowing the edentulous codes at a site with an existing implant. The membrane placed during implant placement is the boundary case worth reading carefully: the descriptor for the per-implant codes names both uses, peri-implant defects and implant placement, so once the fixture is in, the site is an implant site. That is the codebook, not one carrier's reading of it.
Does insurance cover D6107?
Only where the plan covers implants. Cigna's IMPLNT-13 guidelines allow D6106 and D6107 for plans that provide coverage for surgical placement of implants where the implant meets plan guidelines, and disallow the codes on plans without that coverage. Delta Dental Insurance Company's CDT 2023 summary lists both per-implant GTR codes as not a benefit of most of its plans, with the fee falling to the patient. The practical move is to route verification to the implant rider rather than the periodontal benefit, and to settle the patient's share before the surgery is scheduled. A plan that never benefits the code is not producing a denial anyone can appeal.
Can we bill D6107 and a bone graft on the same implant?
Report them as two lines. The membrane and the graft are distinct procedures and the graft descriptors direct the barrier to be reported on its own, so a case that grafts a peri-implant defect and covers it with a nonresorbable membrane is D6103 plus D6107. Whether both lines get paid is plan-dependent, and Cigna's IMPLNT-13 policy is the first one to check because it disallows the pairing at the same site on the same date of service. Collapsing the two into one line to dodge that denial is the wrong fix. It underreports the surgery and leaves the graft with nothing supporting it if the claim is later reviewed.
