Implant Barrier Membrane Dental Code (D6107): Per Implant

What D6107 covers

D6107 reports placing a nonresorbable barrier membrane 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 two uses, peri-implant defects and implant placement: a membrane over a dehiscence or fenestration as the fixture goes in, or 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.

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. These are cleaning and reshaping procedures, not regeneration.
• The removal of the membrane, which is D4286.

Per implant, not per site

Every other guided tissue regeneration code is counted per site. D6106 and D6107 are counted per implant, and the difference changes the claim.

• 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.
• One fixture with two separate bony defects under the same flap is one line, because there is one implant.
• A single continuous sheet of PTFE laid over two implants is still two lines. The unit is the implant, not the piece of material, so the note has to say how many fixtures the barrier covered.

Site-based counting gets the first two wrong in opposite directions.

On the claim form, 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. 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 boundary decides the most claims, because the graft and the membrane are placed together and often 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 nonresorbable barrier over either one.

The graft codes exclude the barrier and biologic materials and direct them to be reported separately, so a grafted peri-implant defect covered with a PTFE membrane is two procedures on two lines. Rolling the membrane into the graft line, or into a blended fee-schedule entry, underreports the surgery. Reporting a membrane with no graft when graft material was placed does the same in reverse. How the implant membrane pair compares with the natural-tooth and edentulous pairs is laid out in the bone graft dental codes guide.

Coding the pair correctly and getting it paid are separate questions. Cigna’s 2026 DPPO guidelines, policy IMPLNT-13, carry two same-site, same-date disallows on D6106 and D6107:

• Alongside any other allowable bone graft procedure. This is the familiar bone-graft rule, the same restriction OS-09 applies to D7956 and D7957.
• Alongside any other peri-implant regenerative procedure. This one has no OS-09 equivalent, and it is why the per-implant codes are tighter than their edentulous counterparts. It reaches past grafting into the rest of the regenerative work around a failing fixture.

On a Cigna DPPO, the clinically standard graft-plus-membrane case loses the membrane line by policy, not by error, and so does a membrane paired with another regenerative procedure at the same fixture on the same day. Other plans pay both lines. Confirm which you have at verification and take financial consent before surgery, because a policy bundling rule leaves nothing to resubmit.

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 enforce 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. A membrane belongs to exactly one family, and the note has to say which.

The membrane placed during implant surgery generates the most argument. The D6106 and D6107 descriptor names implant placement as one of its two uses, so a barrier placed as the fixture goes in belongs to the implant family, not the edentulous one. That is a codebook rule, not a carrier position. 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 has no fixture at the site and belongs to the edentulous family.

The removal visit is a separate code

CDT 2023 created D6107 and D4286 in the same action, so retrieval was never folded into D6107 the way it once sat inside the natural-tooth code, and reporting it separately is not optional. Whether it pays mostly turns on one fact: whether your office placed the barrier. The D4286 page works through where the carriers land and what to do when the removal denies.

On the day of surgery, put the second appointment in the treatment plan and the quote, schedule the D4286 visit, and record on the account who placed the membrane. 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 on 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 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.

Route verification to the implant benefit. A checklist that only asks about periodontal benefits will produce quotes the plan never intended to honor.

Where it is covered, the criteria are measured. Cigna’s allowable conditions require 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 alone 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. It 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 word that makes this line D6107 instead of D6106, and it tells scheduling that a retrieval visit is owed on this site.
• Periodontal charting around the implant and current radiographs, since 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.
