July 14, 2021
Kyle Summerford's monthly column guides office managers through the tricky world of dental coding.
Kyle L. Summerford, Editorial Director

This month I discuss how and what to pay attention to when submitting for porcelain/ceramic onlays. Find out how to get it covered by most dental plans.

Happy coding! 


D2642: Onlay porcelain/ceramic - two surfaces

D2643: Onlay porcelain/ceramic - three surfaces 

D2644: Onlay porcelain/ceramic - four surfaces 

Purpose: To replace the cusp(s) of a single tooth using a laboratory-processed or CAD/CAM porcelain ceramic “puzzle piece." There are many variables involved when it comes to dental insurance coverage and reimbursement.

  • Most insurance plans will pay for an onlay once every 10+ years, due to limitations.
  • Submitting a clear written narrative explaining the number of cusps and surfaces replaced and long-term prognosis can help facilitate approval in most cases.
  • If replacement, provide previous seat date and reason for replacement (i.e., open margins, distal decay). 
  • If reporting a buildup or resin composite on the same tooth at the same visit, insurance plan will deny.
  • Providing x-rays, narrative, recent periodontal charting and photographs will ensure a smooth claim approval or denial and alleviate the need to submit additional information to the insurance company at a later date.
