Understanding PPOs

Hold harmless agreements, affiliated carrier clauses and most favored nation clauses can be very confusing to dentists who are about ready to sign a participating provider agreement with a dental benefits plan. 

Have you heard of the term disallowed procedure?  What exactly does that mean?

The answers to these questions and information on clauses typically found in preferred provider organization (PPO) contracts can be found at the ADA Center for Professional Success in a video titled: “Signing the Contract: Understanding PPOs."

For further information on PPOs and contracts, please contact ADA staff in the Center for Dental Benefits, Coding and Quality at (800) 621-8099 or
