D6090 is the CDT code for the repair of an implant-supported prosthesis — repairing or replacing a damaged component of an implant crown, bridge, or fixed prosthesis while the underlying implant remains stable and intact.
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 D6090 Code
Report D6090 when a part of an existing implant-supported prosthesis is repaired or replaced — for example, repairing a fractured crown or framework, replacing a damaged prosthetic component, or fixing porcelain on an implant restoration — and the implant itself is sound.
D6090 is a repair, not a re-cement and not a new restoration. If the prosthesis simply came loose and is recemented, use D6092 (crown) or D6093 (fixed partial denture). If a replaceable attachment part (like a LOCATOR insert) is swapped, that is D6091. If the prosthesis is being remade rather than repaired, use the appropriate crown, retainer, or denture code. Pick D6090 only when an existing implant prosthesis is actually being repaired.
Documentation & Clinical Scenarios
Repair claims should describe exactly what was fixed:
- Implant site / prosthesis involved and its type (single crown, bridge, fixed prosthesis).
- What failed — fractured framework, chipped porcelain, broken component, etc.
- What was repaired or replaced, and confirmation the implant remains stable.
- A clinical note / narrative of the repair, often with a radiograph or photo of the damage.
Replacing a separate attachment part may belong under D6091, and re-cementing belongs under D6092/D6093 — keep those distinct from a true repair under D6090.
Insurance & Billing Tips
- Verify repair benefits — some plans cover prosthesis repairs, others limit or exclude them.
- Document the failure and the fix with a narrative and image; repairs are often manually reviewed.
- Check time-since-placement rules; repairs shortly after seating may be considered part of the original service.
- Distinguish repair from re-cement and replacement so you don't bill D6090 when D6092/D6093 or a new prosthesis code applies.
- Note any warranty or lab remake terms that may affect what is billable.
Example Case
A 62-year-old patient with an implant-supported bridge fractures a section of the porcelain while eating. The dentist confirms the implants are stable and repairs the damaged porcelain on the existing prosthesis rather than remaking it. The office documents the failure and the repair with a photo and narrative, verifies the plan's repair benefit, and files the service as D6090 — distinct from a re-cement or a new bridge — and it is paid because the documentation clearly showed an existing implant prosthesis being repaired.
Patients call when "my implant crown chipped" or "part of my implant bridge broke" — not D6090. DentalReception AI answers those calls 24/7, books the repair visit live into your schedule, and captures insurance details, while clinical and coverage questions route to your team.

Frequently Asked Questions
What's the difference between D6090 and D6092?
Service type. D6090 is a repair of an implant-supported prosthesis — fixing or replacing a damaged component — while D6092 is a re-cement or re-bond of an implant/abutment-supported crown that came loose but isn't damaged. If nothing is broken and you simply re-attach the crown, use D6092; if a part is repaired or replaced, use D6090.
What does D6090 include?
It covers repairing or replacing a part of an existing implant-supported prosthesis while the implant stays stable — such as a fractured framework, chipped porcelain, or a broken prosthetic component. It does not include re-cementing a loose restoration (D6092/D6093), replacing a separate attachment part (D6091), or making a new prosthesis, which are coded separately.
Will insurance cover an implant prosthesis repair?
It depends. Some plans benefit repairs, others limit or exclude them, and repairs soon after the original seating may be bundled into that service. Verify the repair benefit and any time-since-placement rules, and submit a narrative and image of the damage, so the claim is reviewed and reimbursed accurately.
Do I need a pre-authorization for D6090?
Because repair coverage varies and these claims are often manually reviewed, a pre-estimate or strong documentation is wise. Submitting a narrative and a photo or radiograph of the failure up front helps confirm the benefit and lets you quote the patient an accurate out-of-pocket amount before the repair.
