As a dental insurance broker, you work with many industry terms—DHMO, DPPO, MOOP, CYM, and more. It’s no surprise that employers and employees have questions about what these terms mean and how/if they affect costs, like the differences between DHMO and DPPO plans.

When brokers can break down complex concepts in an uncomplicated way, it builds trust and leads to better benefit decisions.

One common area of confusion is how DPPO (Dental Preferred Provider Organization) plans handle out‑of‑network claims. DPPO plans are popular because they give members flexibility to visit both in‑network and out‑of‑network dentists. In fact, PPO‑style plans make up most of the private dental coverage in the U.S., accounting for roughly 80–90% of employer‑sponsored and individual dental plans.

Unlike DHMO plans, DPPO plans typically do not use fixed copays. Instead, members pay coinsurance, which is a percentage of the covered amount. That covered amount depends on whether the plan uses UCR or MAC pricing when care is received out of network.

Understanding that difference helps brokers explain why costs can vary so much between providers. 

Key Takeaways:

• DPPO plans allow members to visit out‑of‑network providers.
• Out‑of‑network care usually costs more.
• UCR plans base payment on regional charge data.
• MAC plans base payment on network negotiated fees.
• Clear explanations help set realistic cost expectations.

What’s the Difference Between UCR and MAC?

A common broker question is whether a DPPO plan processes payment based on UCR or MAC—and what that means for members.

UCR stands for Usual, Customary, and Reasonable. UCR amounts are based on what providers in a specific geographic area typically charge for a service. Insurers often rely on third‑party benchmarks, such as FAIR Health, or their own claims data to set these values. The goal is to reflect local market pricing rather than a single negotiated fee.

How Does a UCR‑Based Plan Work?

Here’s a simple example.

A member visits an out‑of‑network dentist for a root canal. The plan covers the procedure at 50%, and the insurer’s UCR amount for that service is $1,500.

• If the dentist charges $1,000 (below UCR):
  • The plan pays $500.
  • The member pays $500.

If the dentist charges $2,000 (above UCR):

• The plan still pays 50% of the $1,500 UCR amount, or $750.
• The member pays the remaining $1,250.

This difference highlights why provider choice matters in UCR‑based plans. Regional pricing allows flexibility, but higher charges can increase member costs.

What About MAC‑Based Plans?

MAC stands for Maximum Allowable Charge. In MAC‑based DPPO plans, reimbursement is tied to the insurer’s in‑network negotiated fee, even when a member goes out of network.

These negotiated rates are agreed upon between the insurer and participating dentists. When a member sees an out‑of‑network provider, the insurer still uses the in‑network rate to calculate payment.

How Does a MAC‑Based Plan Compare?

Using the same root canal example:

• The dentist charges $1,500
• The plan covers 50%.
• The insurer’s in‑network rate for the procedure is $900.

In this case:

• The plan pays $450.
• The member pays $1,050.

Because MAC‑based plans rely on negotiated fees, staying in network often results in lower out‑of‑pocket costs.

Advantages of Each Plan Design

MAC‑Based Plans

• Often come with lower premiums.
• Work well when most providers participate in the network.
• Can be a good starting option for groups new to dental coverage.

UCR‑Based Plans

• Offer more flexibility for out‑of‑network care.
• Can be helpful for groups in remote or rural areas.
• Reflect local market pricing rather than negotiated rates.

Both designs have value. The key is to help clients understand the tradeoffs before claims are submitted or processed.

Frequently Asked Questions

What does UCR mean in dental insurance?

UCR stands for Usual, Customary, and Reasonable. It refers to payment amounts based on typical charges in a specific geographic area.

What is MAC pricing in a DPPO plan?

MAC pricing uses the insurer’s in-network negotiated fee to calculate payment, even when care is received out of network.

Is UCR or MAC better for dental insurance?

Neither is universally better. UCR offers more pricing flexibility, while MAC often results in lower premiums and stronger incentives to stay in network.

Why do out‑of‑network dental visits cost more?

Out‑of‑network dentists do not agree to insurer fee limits, which can result in higher costs for members.

How can brokers explain UCR vs. MAC more clearly?

Using real‑world examples and setting expectations around provider choice helps clients understand potential cost differences.
