# 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 your state's rule and what applies everywhere regardless.
**We deliberately do not publish a 50-state table of specific day counts here.**
Refund deadlines come from several different sources depending on the state — insurance codes, professional practice acts, licensing board rules, consumer protection statutes, and unclaimed property law — and they are amended without fanfare. A table of specific numbers would be wrong in some states within months of publication, and a wrong deadline is worse than no deadline.
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 medical/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 |
| **Professional practice act / board rules** | Medical, dental, or other 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 usually "promptly" or "within a reasonable time," and licensing boards have disciplined practices under that standard. A **30-day internal policy** is defensible essentially everywhere and simpler than tracking 51 different rules.
## 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.** 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
The fastest and most reliable route. This is a small, cheap question for someone who already knows the answer.
Medical, dental, or other board. Many publish guidance on billing and refund obligations.
For provisions on overpayment and refund timing.
For the dormancy backstop.
And re-check annually.
## The defensible internal policy
Rather than tracking 51 rules, most multi-state groups adopt a single internal standard that meets or beats every state's requirement:
| 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** is simpler to operate and easier to defend than a per-state matrix, and it removes an entire category of tracking. If your counsel identifies a state with a shorter requirement, tighten globally rather than creating an 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 clinician-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 | **This is not your money** |
| Refunding payer money to the patient | Fails the federal obligation and gives money to the wrong party |
| Monthly credit balance review | Burns a third of the 60-day federal window before anyone looks |
