D6190 is the CDT code for a radiographic or surgical implant index — a guide or template that records implant position and helps place implants accurately — reported with a supporting narrative. It's the planning/guide step, billed separately from the implant surgery itself.
Informational only — confirm the official CDT descriptor and your payers' rules independently. This is general guidance, not billing, coding, or clinical advice.
When to Use the D6190 Code
Report D6190 when a radiographic or surgical index, guide, or template is fabricated and used to ensure accurate implant positioning — for radiographic assessment, surgical guidance, or both. It's especially relevant for complex cases, multiple implants, or situations requiring careful navigation around anatomy. The code can cover digital or non-digital, fully or partially guided, single or multiple-unit guides.
Pick the code by what's being billed. D6190 is the index/guide step — not the implant body (D6010), not the abutment (D6056/D6057), and not the final crown. It is a distinct planning service. Because the descriptor reads "by report," the narrative defines exactly what guide was made and why. Do not bundle it silently into the surgical fee; it stands on its own when documented.
Documentation & Clinical Scenarios
Because D6190 is by report, documentation should explain the guide and its purpose:
- Arch/site and confirmation an index or surgical guide was fabricated and used.
- A narrative describing the type of guide (radiographic, surgical, digital/non-digital, single/multiple-unit) and why it was needed.
- Radiograph(s) or planning imaging supporting the case complexity.
- Chart notes documenting fabrication and use of the index.
The implant surgery, abutment, and restoration are coded separately. Keep the planning records in the chart; by-report codes are reviewed, and many plans apply frequency limits (for example, once per arch over a set period) that you'll want to confirm.
Insurance & Billing Tips
- Attach a narrative every time. "By report" means the payer relies on your description of the guide and its purpose.
- Check frequency limits. When covered, D6190 is often limited (for example, once per arch over a multi-year span) — verify before billing.
- Confirm it's a covered, separate benefit. Some plans bundle the index into the surgical fee or don't cover it; verify rather than assume.
- Code per arch where applicable. Document the arch clearly, since limits and benefits are frequently arch-specific.
- Expect manual review. By-report codes are commonly hand-adjudicated; set realistic timelines.
Example Case
A 55-year-old patient is planned for multiple implants in the upper arch near the sinus, requiring precise positioning. The team fabricates a surgical guide from CBCT planning data to control implant angulation and depth. The office documents the planning imaging, writes a narrative describing the digital surgical guide and the anatomical reason it was needed, and files D6190 for the index, with the implant placements coded separately. Because the narrative justified a guided approach and the arch was clearly documented, the claim is reviewed and processed within the plan's frequency allowance.
Patients call about "the planning scan before my implant," not D6190. DentalReception AI answers and books those calls 24/7, captures insurance details, and routes clinical and billing questions to your team. See how it handles implant consultation calls, or book a demo.
Frequently Asked Questions
What's the difference between D6190 and the implant placement code?
The service. D6190 is the index or surgical guide — the planning template that records implant position and guides placement. The implant body placement is a separate procedure (D6010), and the abutment and crown have their own codes. D6190 is billed for the guide step on its own; it is not a substitute for, or a bundle with, the surgical placement, though both may appear on the same overall treatment plan.
Does D6190 include the implant or the surgery?
No. D6190 covers only the radiographic/surgical index or guide. The implant fixture (D6010), the abutment, and the final restoration are all separate procedures with their own codes. An implant case therefore appears on the claim as several line items, and the index is one discrete, by-report component documented on its own.
How often will insurance cover a D6190 index?
When covered, D6190 often carries a frequency limit — for example, once per arch over a multi-year period — and some plans bundle it into the surgical fee or don't cover it separately at all. Because benefits vary and the code is by report, verify the specific plan's coverage and frequency, document the arch clearly, and submit a narrative so the claim is adjudicated correctly.
Do I need a narrative or pre-authorization for D6190?
A narrative is essential because D6190 is a by-report code. Describe the type of guide (radiographic, surgical, digital or non-digital, single or multiple units) and the clinical reason it was needed, and attach supporting imaging. Many plans review these claims manually and apply arch-specific frequency limits, so a pre-estimate and thorough documentation up front help confirm coverage and set the patient's expectations.
