Can you charge your full fee for a service the plan doesn't cover?
MetLife's contracted fee applies to non-covered services too — except in the 43 states whose laws say otherwise, listed in the carrier's own provider manual.
At MetLife the default answer is no: the plan allowance applies whether or not the plan covers the service, so a participating office is held to the contracted fee on a procedure the plan does not pay for. The carrier's own provider manual then names the exception — a list of 43 states where "the fee schedule may not apply to some or all non-covered services", current as of January 1 2025. So the honest answer is state-dependent, and the state list is published in the manual rather than left to inference. Two things stay off the patient's bill whether or not your state is on that list: a service denied as integral to another service, and the components MetLife names as never separately billable. Kaylie has not measured how often an office bills its full fee on a non-covered service; what follows is the carrier's stated policy and the state list it publishes.
What MetLife's own documents say
The rule, stated as a general principle rather than a list of cases:
"A procedure could be a covered service under one plan and a non-covered service under another plan. The plan allowance applies in both situations (except as noted in Appendix A for certain states) and a participant can't be billed any amount in excess of the plan allowance. Many situations may cause a service to not be covered, but regardless of the reason, the allowance applies."
— MetLife Preferred Dentist Program (PDP) Resource Manual, 2025.
The manual then draws a distinction most offices use loosely and MetLife does not:
"Exclusion: Dental services not covered under a particular dental benefit program. (Certain states have laws that allow the dentist to charge their original fee for non-covered expenses.)"
"Non-covered: These are services that are declined for benefits based upon a patient's plan such as but not limited to a frequency limitation but are still subjected to the MetLife PDP fee as by definition they are covered but not payable due to the plan limits."
— same manual. A cleaning denied on a frequency limit is not an excluded service. It is a covered service the plan will not pay for this time, and the schedule still caps what you may charge.
The state carve-out, verbatim from Appendix A:
"Appendix A Non-Covered Services. The fee schedule may not apply to some or all non-covered services in the following states"
The states listed, in the manual's order: Alabama, Alaska, Arizona, Arkansas, California, Colorado, Connecticut, Florida, Georgia, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin and Wyoming — 43 states, "Current as of January 1, 2025" (MetLife Preferred Dentist Program Resource Manual, Appendix A).
Note the hedge in the carrier's own sentence: "may not apply to some or all". The manual does not promise that every non-covered service in a listed state is outside the schedule, and it does not restate each state's statute. It tells you the schedule is not automatically the answer there.
Two categories stay off the patient's bill whether or not your state appears on that list. On denials for bundling:
"When a service is denied and the reason for denial is considered 'integral to another dental service', the participating dentist agrees to the negotiated fee as adjudicated and cannot charge the participant for the denied integral service."
— same manual. Alongside it: unbundled codes are rebundled, and "the participating dentist can only charge the patient up to the rebundled CDT service contracted amount"; a duplicate procedure cannot be charged at all; and infection control, local anaesthesia, irrigation (D4921), tray set-up and materials and laboratory costs — "including Invisalign or any other specialized orthodontic system" — are never separately billable.
The alternate benefit rule sits in the same family and catches offices out for the opposite reason:
"If a benefit determination is made that an alternate dental service meets the plan design contract provisions then the participating dentist can only charge up to the contracted schedule amount for the originally submitted service. The plan benefit will be based upon the alternate procedure."
— same manual. The ceiling is the schedule for what you did; the payment is for what the plan downgraded it to; the gap is the patient's and it is capped.
Other carriers hold the same line. Delta Dental instructs participating providers that for covered services they "agree to accept the plan's allowed amount as payment in full", and warns that inclusive or bundled items — "anesthesia, routine post-operative care, or components of a comprehensive procedure" — are already inside the allowed amount, so "billing these items separately may result in overcharging the patient" (Delta Dental, "Protect your patients beyond the chair: Avoid balance billing issues", FYI, April 23 2026).
Why it depends on the plan
Three things vary, and all three change the answer:
- The state. MetLife's Appendix A names 43 states where the schedule may not bind on non-covered services. That leaves the rest, where it does. The list carries a date and states amend these statutes, so the date matters as much as the list.
- Why the service was not paid. An exclusion, a frequency limit and an alternate benefit determination are three different reasons, and MetLife treats them differently. A frequency denial is explicitly still subject to the schedule.
- The plan. MetLife says plainly that it administers many different benefit plan designs, so whether a given procedure is covered at all is a plan fact rather than a carrier fact. The same code is covered under one plan and not under the next.
What to do
- Ask the payer which category a denial falls in — excluded, non-covered under a plan limit, integral to another service, or an alternate benefit. The word on the remittance decides what you may bill.
- Check your state against the carrier's own list before charging your full fee, and check the date on the list.
- Never bill a service denied as integral, a rebundled component, or a duplicate. Under the agreements quoted here, and subject to your state's law, those are off the patient's bill.
- On an alternate benefit, bill the patient no more than the contracted amount for the procedure you performed, less the plan's payment on the alternate.
- Put the estimate in writing before treatment when a service may be non-covered. The number is knowable in advance in every case described here.
- Do not carry one state's answer to another office in another state. This is the one question in the cluster where the geography, not the plan design, is the deciding fact.
