D6057 is the CDT code for a custom fabricated implant abutment, including placement. Unlike a prefabricated (stock) abutment, a custom abutment is individually designed for the patient's anatomy and implant position, typically using CAD/CAM technology or direct casting. The code covers both the laboratory fabrication of the abutment and the clinical placement onto the implant body.

Get help with D6057 claims →The abutment was individually designed and fabricated by a dental lab (CAD/CAM milled or cast), not selected from a manufacturer's stock inventory. Use D6057. For a prefabricated stock abutment, use D6056 instead.
Anterior implant cases, angled implant placement, or situations requiring a specific emergence profile that a stock abutment cannot achieve. Custom abutments optimize soft tissue contour and crown seating.
D6057 is billed at the abutment placement appointment, which is a separate visit from the implant body placement (D6010). The implant body must be documented in the patient's history for the payer to process the abutment claim.

Individually designed and fabricated by a dental laboratory specifically for this patient. Typically CAD/CAM milled from titanium, zirconia, or PEEK. Designed from an implant-level impression or scan. Better control of emergence profile and angulation. Higher lab cost.
A stock abutment selected from the implant manufacturer's inventory in a standard size. May be modified chairside (reduced in height, adjusted). Faster and lower cost than custom. May not achieve the same emergence profile as a custom design. Includes modification and placement.
Billing tip: The distinction is in how the abutment was made, not how it looks. If the abutment came from a stock catalog and was trimmed chairside, it is D6056. If the lab fabricated it from scratch based on an impression or scan, it is D6057. Document the fabrication method in the clinical notes and keep the lab slip.
Many payers bundle D6057 into the crown code (D6058 or D6065) and pay only one fee. This is a common contract-level policy and may not be a true error. Review the patient's explanation of benefits carefully. If the plan should pay separately, submit an appeal with documentation showing the abutment was lab-fabricated as a distinct component, with a separate lab fee and a separate clinical procedure.
Most payers expect to see a prior D6010 claim for the same tooth before approving an abutment. If the implant body was placed at a different office, or if the patient switched insurers, the payer may not have the history. Include a narrative on the D6057 claim noting the implant body placement date and the provider who placed it. Attach records if available.
Implant procedures including abutments typically require pre-authorization. Submit pre-auth with a periapical radiograph confirming osseointegration, the implant system details, and documentation that the site is ready for restoration. Do not proceed without written approval from plans that require it.
Using D6057 when a stock prefabricated abutment was actually placed is a coding error. Document the abutment type, the lab that fabricated it, and the fabrication method in the clinical record. Keep the lab slip. If audited, you need to show that the abutment was truly custom-made, not selected from a catalog.
A post-osseointegration periapical x-ray showing the implant body fully integrated and crestal bone levels stable. This is the primary clinical evidence that the site is ready for the abutment and supports the D6057 claim.
The laboratory work order must specify that this is a custom-fabricated abutment, not a stock component. The lab invoice should show a custom abutment line item. Keep this documentation in the patient file and provide it on appeal if the claim is bundled or denied.
Document the implant manufacturer, system name, and implant body size placed at D6010. Payers and their claim processing systems verify abutment compatibility. Missing this information can trigger a request for additional information that delays payment.
Note the date the implant body was placed (D6010) and the provider, if different. Include this in the claim narrative. If the payer has no history of the D6010, a brief narrative explaining when and where it was placed prevents a reflexive denial.
Include the pre-auth reference number on the claim. Verify that the approval covers D6057 specifically. Some pre-auths only cover the crown code and must be updated to include the abutment as a separate line.

Learn about our billing servicesD6057 is the CDT code for a custom fabricated implant abutment, including placement. A custom abutment is individually designed and fabricated by a dental lab (typically CAD/CAM milled) specifically for the patient's implant position and anatomy. It is not a prefabricated stock component.
D6057 is for a custom fabricated abutment designed from scratch by a lab to match the patient's anatomy. D6056 is for a prefabricated (stock) abutment from the implant manufacturer's inventory that may be modified chairside. Custom abutments offer better emergence profile control and are used where stock components cannot achieve the desired result.
Yes. The CDT descriptor for D6057 explicitly includes placement. You do not bill a separate placement code alongside D6057. The fabrication and the clinical placement are both covered under the single D6057 code.
D6057 is billed alongside the implant crown code for the same implant. The most common pairing is D6057 with D6058 (abutment supported porcelain/ceramic crown). The implant body (D6010) would have been billed at an earlier appointment.
Common reasons include bundling (the payer combines the abutment into the crown fee), no implant body claim history on file, missing pre-authorization, lack of documentation confirming custom fabrication, and frequency limitations.
D6057 is the abutment component that connects the implant body to the crown. D6058 is the crown itself (abutment supported porcelain/ceramic crown). Both codes are typically billed together on the same date of service for the same implant restoration.
