Why they arise in dental
Estimate-driven overcollection can be reduced by using current eligibility information, the correct fee schedule, and product-specific alternate-benefit rules. When inputs remain uncertain, avoid collecting more than the reasonably supported amount. See Patient responsibility. Point-of-care collection inevitably creates some balances that must be adjusted after adjudication.
Whose money is it?
The determination that governs everything downstream, and the step most often skipped. The obligations differ materially: Patient money. Refund it to the patient under the applicable state deadline, board rule, contract, and financial policy. If the owner cannot be located or the payment remains uncashed, state unclaimed-property law may apply. Payer money. Follow the payer contract and program rules. Federal health care program overpayments may be subject to the 60-day report-and-return rule after identification, and knowing retention can create False Claims Act exposure.1 Dental groups should pay particular attention to Medicaid, including claims administered by dental benefit administrators, and any Medicare or Medicare Advantage business they bill. See Report and return overpayments and DSO enforcement and risk. Posting error. Correct the ledger rather than issuing a refund that creates a second error. Refunding payer money to the patient is a compounding error. You have failed to return an overpayment to the payer and given money to someone not entitled to it. The 60-day clock keeps running. Determine ownership before touching anything.The legal character of holding patient money
Worth stating plainly, because practices tend to treat credit balances as a housekeeping nuisance: It is not your money. It sits on your balance sheet as a liability. Holding it is not a neutral act:- State refund statutes impose deadlines in many states
- Unclaimed property law eventually transfers it to the state, with due-diligence and reporting obligations attached
- Dental boards have disciplined practices for failing to refund
- Consumer protection statutes can reach retention of consumer funds
- Financially, an unrefunded credit balance overstates your cash position relative to your actual obligations
The diligence angle
Track each credit balance to the entity and transaction that is legally or contractually responsible for the refund. The billing entity is an important starting point, but payer terms, the payment source, transaction documents, and applicable law may affect the result. That makes credit balances an acquisition item on both sides of every deal:- Buying: aged patient and payer credits may carry refund and unclaimed-property obligations. Request an aged credit-balance report, test a sample, and have counsel address responsibility in the purchase agreement.
- Selling (eventually, every DSO): years of unresolved credits across many PCs read in a quality-of-earnings review as a liability and a controls failure. The weekly discipline below is cheap; reconstructing it under diligence pressure is not.
The refund method hierarchy
Refund to the original payment method wherever possible. It reconciles cleanly, arrives fast, and cannot get lost in the mail.Why mailed checks are the painful case
Some refunds cannot return through the original payment method and must be sent another way, often by check. These cases need a separate control process. What a check refund actually requires:- Check stock, physical, secured, per bank account
- An authorized signature or approval under the issuing account’s bank documents and the entity’s approved disbursement workflow
- Printing, a printer, alignment, MICR handling
- Envelopes and postage
- A trip to the post office
- Address verification: confirm the address before issuing the check
- Tracking: record whether and when the check clears
- Stale-dated checks, reissue requests, stop payments
- Escheatment, for checks never cashed
When the check is never cashed
Uncashed refund checks do not revert to you. They become unclaimed property, and after a state-specified dormancy period you owe the state, not the patient. The pipeline:- Check goes stale, commonly 90–180 days per the terms printed on your check stock
- Due diligence: complete the state-required owner-contact steps before reporting
- Dormancy period elapses, varies by state and property type
- Report and remit to the state’s unclaimed property administrator
The credit balance discipline
Run the report weekly, not monthly. Aged credit balances are a compliance problem, and the 60-day clock on payer overpayments runs from identification, which a monthly cadence can burn a third of. Resolve within 30 days. Determine ownership, issue the refund, post it against the balance. Never apply a patient credit forward without consent. Applying it to a future visit converts the patient’s money into a prepayment they didn’t agree to. Ask, and document the answer. Reconcile refunds against open card disputes before issuing, to avoid the double-refund trap. See Chargebacks.Sources
