Should a Dental Office Collect the Patient’s Portion Up Front or Bill After Insurance Pays?

How to estimate the patient portion from the fee schedule and benefits

For an in-network patient the estimate starts from the plan’s allowed fee, not the office fee. The difference between the two is the contracted write-off, and for a covered service the contract sets what the plan and the patient owe between them. From the allowed fee come the coinsurance for the procedure’s category, any deductible still unmet, and what is left of the annual maximum.

Open Dental’s manual works one example: a $125 filling covered at 80 percent, with a $50 deductible unmet. The plan pays 80 percent of the $75 left after the deductible, $60, and the patient owes $65. That arithmetic is only as good as its inputs, and each has to be known, not assumed:

• Eligibility on the visit date, and the month the benefit year renews.
• Deductible and annual maximum, and how much of each is already used.
• Coinsurance by category, including where the plan puts crowns, root canals and periodontal care.
• Frequency history, waiting periods, missing-tooth exclusions and downgrades, such as a back-tooth composite paid at the amalgam fee.
• Secondary coverage, and which plan pays first.
• Who checked, on what date, by portal or phone, with the call reference number.

Electronic eligibility checks help, and Open Dental’s manual is candid about their limit: it says most carriers still send very sparse data, frequently only a yes or no on whether the patient is covered, and that it still takes a human to interpret what comes back. The same manual notes that a blank benefit field means unknown, not zero, and that a plan not set to apply downgrades shows an insurance estimate that is too high when the carrier does downgrade. So verification is a named person’s job, done two business days before scheduled treatment, and the printed estimate says what it is: a share calculated from the benefits the plan reported on that date.

When the estimate is wrong: credit balances, refunds and small balances

An estimate can miss either way, and the written policy decides in advance what happens. When the plan pays more than expected, the patient has a credit. Open Dental’s manual describes unearned income as typically a prepayment or an overpayment waiting to be refunded, and its Procedures Overpaid report lists each procedure paid beyond its fee. Give that list one owner and refund on a written clock, for example within 30 days of the EOB, by the method the patient paid.

Credits nobody refunds become a state matter. Florida’s chapter 717, the Disposition of Abandoned Personal Property Act, lists “Credit balances, customer overpayments” as intangible property and presumes such property abandoned after a dormancy period of “5 years from the date the property becomes payable or distributable.” For $50 or more, the holder must send the owner written notice 90 to 180 days before filing; the report “must be filed before May 1 of each year”; and credit balances under $10 “may not be reported.” Overpayments owed to a managed care payor under its contract are excluded from that reporting section. Other states set their own rules; this is the statute’s text, not legal advice.

When the plan pays less, the statement goes out the day the EOB posts, with the EOB line that explains it. Two tools shorten that tail: a card on file with the patient’s separate written authorization to charge the post-EOB difference up to a stated amount, and a small-balance threshold the owner sets in writing, adjusted off under its own adjustment type, never as a PPO write-off. That threshold is for leftover dollars, not the patient’s share itself. The ADA’s Code of Professional Conduct, Advisory Opinion 5.B.1, says a dentist who accepts a plan’s payment as payment in full without telling the plan the patient’s portion will not be collected “is engaged in overbilling.”

For a patient with no coverage for the service, or one who chooses not to file a claim, 45 CFR 149.610 requires a written good faith estimate on scheduling or on request, and treats any question about cost as a request for one. A bill at least $400 above it can be disputed under 45 CFR 149.620. The practice’s attorney confirms how both rules apply.

What the front desk says, and what the written policy holds

The ask is easiest when nothing in it is news. In these sample lines, an example $185 stands in for the patient’s own estimate. At confirmation: “Your plan’s benefits put your share for Thursday at $185. We collect that at the visit, and if the plan pays differently we refund the difference or send a statement.” At checkout: “Today’s estimated portion is $185. How would you like to take care of that?” When asked to be billed: “Our policy is to collect the estimate at the visit, the same for everyone. If today is hard, I can set up a written plan.” The words are the same for every patient, so nobody at the desk decides who gets asked. Where balances are discussed at the counter is for the privacy officer to set: HIPAA’s 45 CFR 164.530(c) requires a covered entity to “reasonably safeguard protected health information to limit incidental uses or disclosures.”

Behind the words sits one page, signed at the first visit and with any treatment plan above an amount the owner sets:

• When payment is due: the estimated portion at the visit, and for lab work, the split between preparation and seating.
• What an estimate is: calculated from benefits the plan reported on a stated date, not a promise of what it will pay.
• After the EOB: a refund within a stated number of days, or a statement due on receipt.
• Payment methods, and any card kept on file, with its own signed authorization and limit.
• Payment plans and outside financing: who may offer them, on what terms.
• Missed seating appointments, what happens to money already paid, and who can approve an exception.

Two federal texts sit behind the payment lines. Regulation Z, 12 CFR 1026.2(a)(17), treats as a creditor a person who “regularly extends consumer credit that is subject to a finance charge or is payable by written agreement in more than four installments (not including a down payment),” and “regularly” means more than 25 times in the preceding calendar year, or in the current one. Read that way, an in-house plan with no interest or other finance charge and no more than four installments after any down payment falls outside the definition; anything longer, or with a fee for paying over time, goes to the practice’s attorney first. On outside financing, the CFPB’s 2023 report on medical credit cards warns that a borrower who has not paid in full when a deferred-interest promotion ends “will owe interest on the full purchase amount, not just the remaining balance,” and it counted about $1 billion in such interest on healthcare charges from 2018 to 2020.

Should crowns and other lab work be paid before seating?

Yes: collect the estimated patient portion for lab work at preparation, in full or in a stated split with the rest due at seating, and write the choice into the policy signed with the treatment plan. The lab’s invoice for a finished case does not depend on the patient coming back, while the plan’s payment can wait for the seat. California’s Medi-Cal Dental handbook, for one, rules out partial payment for an undelivered laboratory crown and says payment “shall be made only upon final cementation.” Commercial plans set their own rules; ask the plans the practice bills most and file the answers with the verification notes.

The claim carries the date the plan’s rule asks for, even when coverage ends between preparation and seating. The ADA’s Advisory Opinion 5.B.4 treats reporting an incorrect treatment date to get benefits a plan would otherwise disallow as an unethical, misleading representation. When verification shows coverage ending before the likely seat date, the patient hears it before the preparation.

In Open Dental, set up as its manual describes, a payment allocated to a treatment-planned procedure stays off the account balance until the procedure is set complete, then moves onto it with an automatic income transfer; the Hidden Payment Splits report lists those prepayments. The manual also says a lab case should always be attached to an appointment, generally the seat. Its Lab Cases list then shows, by default, cases attached to appointments not yet set complete, and with Show Unattached checked, cases attached to none; read with each case’s tracking status (Received or Quality Checked) and checked weekly, it is the list of crowns back from the lab and not seated. When a patient does not come back, the first call offers two times to seat the crown. What the practice may keep or charge for a case never seated depends on the signed policy and state law; the practice’s attorney writes that line before anyone needs it.

How to count what left the office unpaid last month

Open Dental’s Patient Portion Uncollected report answers it directly: for procedures completed in a date range, it lists the fee, the patient portion after insurance and write-offs, adjustments, what the patient paid, and what remains uncollected. Its manual adds two cautions: insurance estimates count only where a claim has been created, and a payment counts only when attached to the procedure. Other systems may carry a similar report under another name; the PMS trainer can point to it. Run it for last month and write down six numbers:

• Visits that left with an uncollected portion, and the dollars, against all visits with a patient portion.
• How much of that has come in since, and how much is still open.
• Days from EOB posted to statement sent, for a sample of 20 balances.
• Credit balances older than 30 days, and refunds sent this month.
• Lab cases prepared and not seated, and the prepayments held against them.
• Small-balance adjustments: count, dollars, and the threshold used.

Illustrative example: a hypothetical practice finds 410 of 900 visits left with an uncollected portion, $31,000 in all; $19,000 has come in since; statements went out a median of 9 days after the EOB; 37 credits older than 30 days total $4,800; 6 crowns are prepared and not seated. The first and fourth lines are the findings: money not asked for at the desk, and money the practice holds that belongs to patients. Kept monthly, the page sits beside the gap between net production and collections, since patient balances are one place that gap lives. One named person works yesterday’s list each morning, the lab cases and credits weekly, and the six numbers monthly.

When to keep it in-house, and where the Revenue Review fits

If last month’s uncollected list is short, credits go back on the policy’s clock, statements leave the day the EOB posts, and unseated crowns are a handful with dates on them, the front desk has done the work and there is nothing here to buy. If payments are not attached to procedures, the first fix is posting, and the PMS trainer is the right call.

The Revenue Review counts this under the Invoice → Payment hand-off, beside claims never sent, claims unpaid and write-offs by plan. It takes two weeks. It works from read-only access to the practice’s own reports, starting with aggregate reports that carry no patient names, and ends in a written report the practice keeps: each leak with a monthly dollar figure wherever the records support one, a ranked list of what to fix, and a 90-day plan. It gives no legal or tax advice and is built for owner-led practices with $2 million or more in annual collections and two or more doctors or locations.

If the numbers point here, the next step is a free 20-minute call, where we say whether the Review fits, including when the count above, run in-house, is all the practice needs.
