# Patient refund timing requirements by state
> How state refund obligations are structured, where to find your state's rule, and the federal overlay that applies everywhere.
State obligations to refund patient overpayments vary in both **deadline** and **source of authority**. This page explains how to find the applicable state rule and identifies requirements that apply more broadly.
Dental offices often collect an estimated patient portion before the payer adjudicates the claim. Downgrades, frequency limits, remaining annual maximums, and other benefit terms can change the final patient responsibility and create a credit balance. See [Refunds and credit balances](/concepts/payments/refunds-and-credit-balances).
**We deliberately do not publish a 50-state table of specific day counts here.**
Depending on the state, refund deadlines may come from insurance codes, professional practice acts, licensing board rules, consumer protection statutes, or unclaimed property law. These requirements can change without much notice, so a static table can quickly become inaccurate.
What follows is how to determine your state's rule reliably, plus the obligations that apply everywhere. **Confirm your state's current requirement with counsel or your state dental board before setting your internal policy.**
## The four sources of a refund obligation
Check all four for your state; more than one may apply, and the shortest governs.
| Source | Where to look | Typical character |
| --------------------------------------- | --------------------------------------------------- | ----------------------------------------------------------------------------------------------------------- |
| **Insurance code / prompt-pay statute** | State insurance code | Often addresses payer-to-provider refunds and provider-to-payer, and sometimes reaches patient overpayments |
| **Dental practice act / board rules** | State dental board regulations | Frequently frames failure to refund as unprofessional conduct, sometimes without a specific day count |
| **Consumer protection statute** | State consumer law | Retention of consumer funds |
| **Unclaimed property law** | State treasurer or unclaimed property administrator | The backstop, after the dormancy period, it goes to the state |
**Where no explicit statutory deadline exists**, the practical standard is often "promptly" or "within a reasonable time," and licensing boards have disciplined practices under that standard. Many groups use a **30-day internal policy** as a conservative operating baseline, subject to any shorter legal or contractual requirement.
## What applies everywhere
### The federal 60-day rule, payer overpayments
For **Medicare and Medicaid overpayments**, 42 U.S.C. § 1320a-7k(d) requires report and return within **60 days of identification**, and retaining an identified overpayment creates **False Claims Act** liability.
CMS revised the identification standard effective January 1, 2025, replacing "reasonable diligence" with the FCA knowledge standard.1
**This is a federal obligation independent of any state rule, and it applies to money owed to the payer, not the patient.** In dentistry it runs chiefly through Medicaid, including claims paid by the state's dental benefit administrator. Determining whose money a credit balance represents is therefore the first step in every refund. See [Report and return overpayments](/guides/compliance/report-and-return-overpayments).
### Contract terms
Your payer participation agreements typically specify refund obligations for payer overpayments, often with the payer entitled to recoup by offset if you don't. Read them; they may be shorter than any statute.
### Escheatment
Unrefunded and unclaimed, the money eventually becomes **unclaimed property** owed to the state, reported to the state of the **owner's last known address**. Dormancy periods vary by state and property type. See [Escheatment by state](/reference/banking/escheatment-by-state).
## How to determine your state's rule
Counsel familiar with the state's dental and insurance rules can identify the governing authority and any shorter deadline.
Many state dental boards publish guidance on billing and refund obligations.
For provisions on overpayment and refund timing.
For the dormancy backstop.
And re-check annually.
## A sample internal policy
Many multi-state groups adopt one conservative internal standard, then adjust it wherever state law, payer contracts, or program rules require a shorter period:
| Step | Timing |
| --------------------------------------- | --------------------------------------------------------------------------- |
| **Credit balance report** | **Weekly**, not monthly. The 60-day federal clock runs from identification. |
| **Determine whose money it is** | Within 3 business days of detection |
| **Payer overpayments** → 60-day process | Immediately routed |
| **Patient refunds issued** | **Within 30 days** of detection |
| **Refund posted against the balance** | Same day as issuance |
| **Uncashed check follow-up** | 30 and 60 days after issuance |
| **Due diligence letter** | Before the stale date |
| **Escheatment reporting** | Per state dormancy period |
A **30-day patient refund standard** can simplify operations compared with a separate internal target for every state. If counsel identifies a shorter requirement, consider tightening the standard globally instead of creating a one-state exception.
## Multi-entity considerations
| Item | Implication |
| ---------------------------------------------------- | --------------------------------------------------------------- |
| Refunds are drawn on **that PC's** account | You cannot refund one state's patient from another PC's account |
| Each PC needs its **own check stock and signer** | The PC's authorized signer is the dentist-owner |
| The applicable state rule follows the **PC's state** | And escheatment follows the **patient's** address |
| The credit balance report runs **per entity** | Aggregate-only review hides which entity owes what |
## What not to do
| Practice | Problem |
| ------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------- |
| Applying a patient credit forward without consent | Converts their money into a prepayment they didn't agree to; in some states a refund-timing violation |
| Holding small balances indefinitely under a de minimis policy | It is still the patient's money, and still becomes unclaimed property |
| Writing uncashed refund checks back to income | The amount remains a liability and may become reportable unclaimed property |
| Refunding payer money to the patient | Fails the federal obligation and gives money to the wrong party |
| Monthly credit balance review | Can consume much of the 60-day federal window before staff begins the review |
