D6190 is the CDT code for the radiographic or surgical implant index, the planning aid that records implant position or guides placement, reported by report rather than as the surgery itself.
The trouble on D6190 is that it is a planning aid, not a procedure, and carriers treat planning aids very differently. Some plans pay it as a standalone line, some fold it into the surgical fee, and some deny it outright as part of the global implant case. Because it carries the by-report flag, a claim without a narrative explaining what the index was and why it was needed tends to stall before anyone even looks at coverage.
What D6190 covers
D6190 reports the radiographic or surgical implant index: the planning aid a dentist uses to position an implant accurately. In practice this is the radiographic template, surgical guide, or positional index fabricated for an implant case, whether it is used to evaluate the site on imaging, to guide the drill at surgery, or both. The code reports the index itself. It does not report the implant surgery, the abutment, or the crown.
The code carries the by report designation. That is not a footnote, it is the operating instruction for the whole code: the claim has to include a narrative describing what the index was and why the case needed it. A D6190 line with no report attached is a claim a carrier cannot adjudicate.
The distinguishing axis: it is a planning aid, not a procedure
This is the thing to get right on D6190, and the place it gets miscoded. D6190 is not a step in the surgery. It is the planning and positioning aid that supports the surgery, billed on its own line and adjudicated on its own terms.
That separates it cleanly from the surgical codes it sits next to:
- D6010 is the surgical placement of the endosteal implant body, the surgery that seats the fixture in bone. D6190 is the index that helps plan where that fixture goes. Different line, different procedure.
- D6011 is second-stage implant surgery, the visit that surgically uncovers an implant after it has integrated. D6190 is not a surgical visit at all.
- The abutment and crown codes (D6056 prefabricated abutment, D6057 custom abutment, D6058 abutment-supported ceramic crown) are the restorative parts that follow. D6190 is upstream of all of them, in the planning phase.
So D6190 is neither the surgery, nor the second-stage uncovering, nor any restorative component. It is the index used to plan and guide the case. The D6010 page already points to it as a surgical guide fabricated in advance, and that is exactly the role: the guide, not the placement.
Coverage reality: standalone, bundled, or excluded
How a plan handles D6190 is plan-dependent, and the three common outcomes are far enough apart that guessing wrong creates a patient-billing problem.
- Paid as a standalone service. Some plans recognize the index as a separately payable planning step and pay an allowable on the D6190 line.
- Bundled into the global implant fee. Some plans consider the index part of the surgical procedure and pay nothing extra for it, the same way they treat surgical prep as included in the placement. The line is not denied so much as absorbed.
- Excluded with the rest of the case. Plans that exclude implants categorically exclude the index too. If implants are not a covered benefit, D6190 is not either.
None of this is knowable from the general benefit summary. Verify how the specific carrier treats the implant index before the index is fabricated, and build the patient estimate around the plan’s actual behavior.
When to bill D6190
Bill D6190 when a radiographic or surgical implant index is fabricated for an implant case: a radiographic template to evaluate the site, a surgical guide to direct placement, or a positional index that records implant orientation for the restorative phase. Report it with a narrative describing the index and the reason it was needed.
Do not bill D6190 for:
- The surgical placement of the implant body. That is D6010.
- Second-stage surgery to uncover an integrated implant. That is D6011.
- A bone graft placed at the time of implant placement. That is D6104.
- The abutment or crown. Those are the restorative codes (D6056, D6057, D6058).
The index is the planning aid. Everything that touches the implant surgically or restoratively is a different code.
Documentation that supports the claim
Because the code is by report, the narrative does most of the work. A D6190 claim is strongest when it includes:
- What the index is. Radiographic template, surgical guide, or positional index. Name it plainly.
- Why the case needed it. The clinical reason: planning around an anatomical structure, positioning multiple implants, or guiding placement in a site that calls for precision.
- How it ties to the implant. The implant site or sites the index serves, so the planning aid connects to the surgical case on the record.
For the patient record, keep the index design, the imaging or models it was built from, and the date it was fabricated. If the carrier requests support after submission, that record is what answers the request.
What to get right in your PMS
The menus differ across Open Dental, Dentrix, Eaglesoft, Curve, and Carestream, but the setup that keeps D6190 from stalling is the same:
- Flag D6190 as a by-report code in the system. It should not be possible to send the line without a narrative attached. The single most common D6190 problem is a bare line item, and a required-narrative flag prevents it at the source.
- Keep the index and the surgery on separate lines. D6190 for the index, D6010 for the placement. They are fabricated and performed at different times and pay on separate adjudications, so they should never share a line.
- Record how each carrier treats the index. Standalone, bundled, or excluded. Capture it on the plan record once so the next implant case starts from the carrier’s known behavior instead of a fresh guess.
- Set the patient estimate to the plan’s actual handling. If the carrier bundles the index into the surgical fee or excludes it with the implant, the estimate should say so before the index is made, not after the EOB lands.
- Store the index narrative as a reusable template. The structure is the same every time (what it is, why it was needed, the implant it serves), so a template the team fills in per case makes the by-report requirement routine instead of an afterthought.
FAQs
- What is the dental code for a surgical guide?
- D6190, the radiographic or surgical implant index. It reports the index or guide used to plan and place implants, including a radiographic template, a surgical guide, or a positional index. The code is written as by report, so a narrative has to accompany the claim describing what was fabricated and why. D6190 reports the planning aid only. The surgery that places the implant is D6010, a separate code on a separate line.
- Is D6190 a current CDT code for 2026?
- Yes. D6190 is active in CDT 2026, unchanged, in the implant services section. No implant codes were deleted for 2026 (the six deletions that year were elsewhere, including D9248 and D1352), so the whole implant family around it, D6010 for the implant body and the abutment and crown codes, also remains in place. The by-report designation is part of the code itself, not a recent change.
- Does insurance pay for D6190 separately?
- It depends on the plan, and there is no single answer. Some plans treat the index as a separately payable planning service. Others consider it part of the global implant surgery and pay nothing extra for it, the same way they bundle the surgical prep into the placement fee. And many plans that exclude implants categorically exclude D6190 along with the rest of the case. Verify how the specific carrier handles the index before fabricating it, and set the patient estimate to the plan's actual behavior, not an assumption that it pays on its own.
- Why was D6190 denied for no documentation?
- Because it is a by-report code, and a by-report claim without a report has nothing to adjudicate. Carriers reading D6190 expect a narrative that names what the index was (radiographic template, surgical guide, positional index), why it was needed for the case, and how it ties to the implant being placed. A bare line item with no narrative is the most common reason this code stalls or denies for insufficient information. The fix is to attach the narrative on the first submission, not after the rejection.
- What's the difference between D6190 and D6010?
- D6190 is the planning aid. D6010 is the surgery. D6190 reports the radiographic or surgical index used to plan or guide where the implant goes. D6010 reports the surgical placement of the implant body in bone. They can appear on the same case, with the index fabricated in advance and the placement done later, but they are separate codes, separately adjudicated, and one being covered says nothing about the other. The index is not the surgery and the surgery is not the index.
- Can D6190 be billed for a digital surgical guide?
- The code covers the radiographic or surgical implant index regardless of how it was produced, so a guide planned and printed from a digital workflow is reported the same way as one made by conventional means. What matters for the claim is the narrative, not the fabrication method: describe the index, the case it serves, and the reason it was needed. Whether the carrier pays for it is a separate, plan-dependent question that the digital-versus-conventional distinction does not change.
