What is the D6120 dental code?

It's the CDT code for an implant-supported retainer crown — porcelain fused to titanium and titanium alloys — used as one anchoring end of a fixed bridge (FPD) that connects directly to the implant, with no separate billed abutment.

How is D6120 different from a single implant-supported PFM crown?

Same material and construction, different role and billing: a single crown restores one isolated tooth and is billed alone. D6120 is a retainer — one end of a multi-unit bridge — billed alongside the bridge's pontic(s) and any other retainer(s).

How does D6120 relate to D6076, D6098, and D6099?

They're the same implant-supported PFM retainer construction, differing only by alloy class: D6076 (high noble), D6098 (predominantly base), D6099 (noble), D6120 (titanium) — together the complete metal-class set.

Is it billed per retainer or per bridge?

Per retainer unit. Each retainer and each pontic in a bridge case is reported under its own applicable code; the bridge's total is the sum of those units.

Is it covered by insurance?

Coverage varies by plan. Reporting the correct support type (implant-supported), construction (PFM), and alloy class (titanium and titanium alloys) for each retainer matters for accurate adjudication. Missing-tooth clauses and alternate-benefit downgrades are common for implant bridge work. Verify coverage with the relevant plan.

D6120 Dental Code: Implant-Supported PFM Retainer Crown (Titanium And Titanium Alloys)

Code Summary

D6120 is the CDT code for an implant-supported retainer crown for a fixed partial denture (FPD/bridge), porcelain fused to titanium and titanium alloys — a PFM retainer unit connecting DIRECTLY to the implant (no separate billed abutment), using commercially pure titanium or a titanium alloy — biocompatible, lightweight, and outside the noble-metal classification system entirely. It is the titanium and titanium alloys member of the implant-supported PFM retainer family (D6076 high noble, D6098 predominantly base, D6099 noble, D6120 titanium), the bridge-retainer counterpart of the single-crown grid built around D6066/D6082/D6083/D6084.

What D6120 means

D6120 covers an implant-supported retainer for a porcelain-fused-to-metal FPD, using titanium and titanium alloys. "D" is dental, "6" places it in the implant services area, and the remaining digits mark this as the titanium and titanium alloys implant-supported PFM retainer. A "retainer" is the end unit of a bridge that anchors it — here, directly to the implant, with the porcelain-covered pontic(s) spanning to the next abutment or retainer. 'Implant-supported' means no separate billed abutment; 'porcelain fused to titanium and titanium alloys' means a PFM crown form using commercially pure titanium or a titanium alloy — biocompatible, lightweight, and outside the noble-metal classification system entirely.

The key distinction from the single-crown family (D6066/D6082/D6083/D6084) is ROLE, not material: those codes describe a standalone crown restoring one tooth in isolation. D6120 describes the same PFM/titanium and titanium alloys construction, but functioning as one retaining end of a multi-unit bridge — reported once per retainer unit, with the pontic(s) reported separately (D62xx series) and any other retainer reported under its own applicable code. Mixing up a retainer code with a single-crown code, or reporting a retainer when the tooth is actually restored in isolation, is a common and often-audited coding error.

D6120 sits in the metal-class grid alongside D6076 (high noble), D6098 (predominantly base), D6099 (noble), and D6120 (titanium) — together the complete implant-supported PFM retainer set, mirroring D6066/D6082/D6083/D6084 for single crowns and D6069-D6071/D6195 for abutment-supported retainers.

When it's typically used

D6120 is reported for each implant-supported retainer unit of an FPD (bridge) that is porcelain fused to titanium and titanium alloys, where the retainer connects directly to the implant with no separate billed abutment. It applies per retainer, not per pontic — pontics are reported separately, and any other retainer in the same bridge (whether tooth-, abutment-, or implant-supported) is reported under its own applicable code.

How much does D6120 cost?

An implant-supported PFM retainer in titanium and titanium alloys is priced as one component of a larger bridge case: the retainer fee reflects the alloy tier (titanium and titanium alloys) plus PFM lab fabrication, billed per retainer unit, with pontics and any additional retainers billed separately. Total case cost is the sum of all retainer and pontic units. Coverage for implant-supported bridge work varies by plan, and missing-tooth or alternate-benefit clauses are common. Verify coverage with the relevant plan before treatment.

Is D6120 covered by insurance?

Coverage for D6120 varies by plan. Because this is a multi-unit case, claims typically list each retainer and pontic as its own line — reporting the correct SUPPORT type (implant- vs abutment- vs tooth-supported) and METAL CLASS (titanium and titanium alloys, not another tier) for each unit matters for accurate adjudication. Many plans apply missing-tooth clauses, alternate-benefit downgrades, or frequency/replacement limitations to implant bridge work. Verifying benefits before treatment helps avoid surprises.
