MetLife PDP vs PDP Plus: what's the difference?

Two MetLife networks governed by one provider manual — different network composition, not interchangeable, and no published fee differential between them.

PDP and PDP Plus are two MetLife dental networks, not two plan designs. PDP is the older and narrower network; PDP Plus is the broader one. Reading across MetLife's plan documents, these are two separate network selections rather than two labels for one network, and a member enrolled on a PDP plan does not have access to PDP Plus dentists. Both are governed by the same provider manual and the same claims rules, so the payment mechanics, the plan-allowance ceiling and the non-covered-service rules are identical. What differs is network composition and, in practice, which fee schedule the office signed. On the question everyone actually asks — how much more or less does one pay than the other — no MetLife document in our sources states a differential. We are not going to invent one.

What we measured

Paid dental claim lines across the practices we serve, aggregated, and measured across all carriers, not MetLife alone. This is the measurement that bears on the PDP-versus-PDP-Plus question, because the usual way an office tries to answer it is by comparing a handful of remittances. One observation misses the stable answer by a median 16.5%, and half the plan-level cells Kaylie measured rest on exactly one. A difference of that size between two remittances is inside the noise, and reading it as "PDP Plus pays more" is not a finding.

What MetLife's own documents say

MetLife's fee schedule and its table of maximum allowable charges are the same object, and the manual that defines it covers both networks:

"MetLife's Table of Maximum Allowable Charges or Fee Schedule applies to dental procedures performed on eligible members participating in MetLife's Preferred Dentist Program (PDP). The allowances represent the maximum amount you're contractually allowed to collect from the plan participant for dental services rendered (including all amounts reimbursed by MetLife). These allowances may also be referred to as the 'plan allowance.'"

— MetLife Preferred Dentist Program (PDP) Resource Manual, provider manual covering PDP, PDP Plus and the federal dental plans, with Appendix A current as of January 1 2025.

On why two MetLife patients at the same office pay different amounts, and it is not the network:

"MetLife administers many different benefit plan designs, which result in various levels of benefit reimbursement and covered services. Whenever a participant receives any services from a participating dentist, the plan allowance applies. When the plan allowance is not reimbursed in full or in part by the benefit plan, any difference is the responsibility of the participant up to the plan allowance. The participant is not responsible for any amount that exceeds the plan allowance."

— same manual.

And the rule that quietly caps a lot of offices below the schedule:

"Submit your normal charges when sending claims to MetLife. Our claims payment system will adjust the fees so that the Explanation of Benefits (EOB) shows both the submitted charge and the allowable charge… When your usual charge for a procedure is lower than the plan allowance, your usual charge will become the maximum amount you may bill a participant."

— same manual. That holds on PDP and PDP Plus alike, so an office whose fee list is below the schedule will see no difference between the two networks on those codes at all.

MetLife's directory asks you to select a network type, PDP among them. That is a directory-search step rather than a statement about how the two networks relate, so read it as one more place the distinction shows up, not as proof of it.

Why it depends on the plan

The network is a property of the plan the employer bought, and the member cannot cross between them. That is the practical consequence for an office: verifying that a patient "has MetLife" and that you "take MetLife" establishes nothing. You need the network the plan uses and the network your contract is on, and if they do not match, the patient is out of network at your office no matter how many other MetLife patients you treat in network.

Everything else about the payment is plan-level rather than network-level. The plan allowance applies to covered and non-covered services alike. On an alternate benefit determination, "the participating dentist can only charge up to the contracted schedule amount for the originally submitted service" while the plan pays on the alternate procedure. Out of network, MetLife's commercial plans pay a reasonable and customary charge — the lowest of the dentist's actual charge, the dentist's usual charge, and the area customary charge at the plan's percentile — and the percentile is an employer purchase. MetLife's federal plan used the 80th percentile in its 2021 brochure and moved to the in-network plan allowance in its 2026 brochure.

What we cannot tell you is how the two schedules compare. The sources establish that the networks differ in composition and are not interchangeable; nothing in them states a fee differential, in dollars or in percent. The only place that comparison exists for your office is your own two contracted schedules, if you hold both.

What to do

• Verify the network, not the carrier. Ask which MetLife network the plan uses, and confirm which network your contract is on. "In network with MetLife" is not an answer.
• Load the schedule you actually signed. If you hold both, keep them as two schedules; do not merge them into one MetLife list.
• Compare the two yourself, code by code, if you hold both contracts. That is the only reliable comparison available, and it is specific to your office.
• Do not estimate a PDP-to-PDP-Plus differential from a few remittances. At one observation the typical error is larger than most differentials would be.
• Check your own fee list against the schedule. Where your usual charge is lower, it becomes the cap on what you may bill the patient, on either network.
• Ask for the out-of-network percentile separately. It is a plan attribute and it is not implied by which network the plan names.
