D6059Abutment Supported Porcelain Fused to Metal Crown (High Noble Metal)

What This Code Covers

D6059 covers a porcelain-fused-to-metal (PFM) crown with a high noble metal substructure, placed on an implant abutment. The crown has a metal core for strength and a porcelain outer layer for esthetics. The high noble metal (containing over 60% noble metals, with at least 40% gold) provides excellent biocompatibility and durability. This is a two-piece restoration where the crown sits on a separate abutment attached to the implant.

Billing Guide

Bill this code when:

• A PFM crown with high noble metal substructure is placed on an implant abutment
• The restoration is abutment-supported (two-piece)
• The metal substructure contains over 60% noble metals (at least 40% gold)
• The abutment is already in place or being placed at the same visit

Do not bill this code when:

• The crown is all-ceramic. Use D6058
• The metal is predominantly base metal. Different code applies
• The crown sits directly on the implant body without a separate abutment. Use D6065 or D6066
• The crown is on a natural tooth. Use D2750

Insurance and Denial Prevention

Key Payer Rules:

• D6059 is typically the standard implant crown code for many payers
• Some payers apply LEAT, paying the base metal PFM rate regardless of alloy
• The abutment is billed separately from the crown
• Pre-authorization may be required

Common Denials and How to Respond:

• Downgraded to base metal rate - The payer is applying LEAT. The patient may owe the difference between the high noble and base metal fees. Document the clinical reason for high noble metal if applicable.
• Implants not covered - Verify plan benefits before treatment.
• Missing abutment documentation - Submit the abutment code and implant records.
