What Is the FQHC 3-Year Rule for Medicare New vs. Established Patient Billing?
Quick Answer
Under the Medicare FQHC prospective payment system (PPS), a patient is generally new if they have not received professional medical or mental health services from any practitioner or site within the FQHC organization in the previous three years. If they have, they are generally established.
For a qualifying medical visit, report G0466 for a new patient and G0467 for an established one.
Scope note: This guidance applies only to traditional Medicare FQHC PPS billing. Medicaid, Medicaid managed care, Medicare Advantage, and commercial plans can differ significantly by state and contract. Always check the payer contract.
Why the FQHC 3-Year Rule Trips People Up
If you came up through CPT, you were taught to think about the professional relationship. Medicare’s FQHC rule does not work that way. It looks at the whole organization, every site, and mental health visits as well.
That’s where errors creep in – and multi-site health centers get hit hardest. The provider in the exam room may never have met the patient, and Medicare can still call them established.
Important distinction: Being new to a provider is not the same as being new to an FQHC. Medicare looks at the organization’s service history, including visits at its other sites.
CPT vs. Medicare FQHC: How the Two Frameworks Differ
| Area | Standard CPT | Medicare FQHC |
|---|---|---|
| Main focus | Physician/QHP and same-group specialty relationship | The FQHC organization and its sites |
| Lookback period | Three years | Three years |
| Prior service at another site | Depends on the applicable group/specialty relationship | Can make the patient established when the site is within the same FQHC organization |
| Mental health services | Governed by applicable CPT professional-service rules | Expressly included in the FQHC patient-status definition |
| Key question | Does the professional relationship meet the CPT definition? | Did the patient receive applicable services from the FQHC organization within three years? |
CPT isn’t wrong. It’s just not the yardstick Medicare uses for an FQHC encounter.
New and Established Patients: The CMS Definitions
New patient: A patient who has not received professional medical or mental health services from any practitioner within the FQHC organization, or from any site within that organization, during the three years before the date of service.
Established patient: A patient who has received professional medical or mental health services from any practitioner within the FQHC organization, or from any site within that organization, during the three years before the date of service.
Put simply, the patient’s history belongs to the organization, not to whoever is seeing them today.
The Three-Step Decision Flow
- Start with the date of service. Count backward from it.
- Pull the last three years of service history, including what was furnished and where.
- Ask: Did the patient receive a professional medical or mental health service from this FQHC organization or one of its sites?
Yes → Established. G0467 may apply.
No → New. G0466 may apply.
After that, confirm the visit qualifies and the note supports it. Then send the claim.
Four Real-World Examples
Example 1: New to the organization
A Medicare patient with no history anywhere in the FQHC organization has a qualifying medical visit in October 2026. They are new, and G0466 may apply.
Example 2: Different site, same organization
Site A, March 2024: the patient has a qualifying professional service. Site B, October 2026: the patient visits another location of the same FQHC. Still established, even at a new site. The earlier visit falls inside the three-year window, so G0467 may apply.
Example 3: A physician joins from private practice
Former private-practice patients follow the physician to the FQHC. Those old visits do not count. With no FQHC history in three years, they are new.
Example 4: An unaffiliated FQHC
A patient seen six months ago at a separate, unaffiliated FQHC is still new to yours. Different organization, different history.
Medicare FQHC Payment Codes at a Glance
| HCPCS | Description |
|---|---|
| G0466 | FQHC visit, new patient |
| G0467 | FQHC visit, established patient |
| G0468 | FQHC visit, IPPE or AWV |
| G0469 | FQHC mental health visit, new patient |
| G0470 | FQHC mental health visit, established patient |
One thing people forget: The G-code sits alongside the HCPCS codes for what you actually did. It does not replace them. Every FQHC-specific payment code reported for an encounter must have a corresponding service line with a HCPCS code describing the qualifying visit.
Same-Day Medical and Mental Health Visits
This one trips up a lot of billers. If a new patient has a medical visit and a mental health visit on the same day, CMS treats them as new for only one. Report the medical visit with G0466 and the mental health visit with G0470. For an established patient, G0467 and G0470 may be reported when requirements are met.
Other payers? Their contracts decide, so check first.
How Patient Status Affects Payment
Here’s where it hits the bottom line. CMS increases the FQHC PPS rate by 34.16% when a patient is new to the FQHC, or when an IPPE or AWV is furnished. The increase is applied after the geographic adjustment factor.
Careful, though: that is an adjustment to the PPS rate, not 34.16% tacked onto every charge. Under the FQHC PPS, Medicare payment is generally 80% of the lesser of the actual charge or the applicable PPS rate.
Common Coding Mistakes to Avoid
- Checking only the current provider’s history instead of the organization’s.
- Missing visits at other sites in the same organization.
- Counting private-practice visits as FQHC history.
- Picking G0466 or G0467 without confirming a qualifying visit.
- Applying Medicare rules to Medicaid or Medicare Advantage claims without checking the contract.
Notice a pattern? Almost all of them come from looking at one provider instead of the whole organization.
Common Coding Mistakes to Avoid
Before you choose G0466 or G0467, check:
- Date of service
- Previous three-year service history
- All locations within the FQHC organization
- Professional medical and mental health services
- New vs. established status
- Qualifying FQHC visit
- Face-to-face requirement
- Appropriate FQHC payment code
- Supporting documentation
- Payer type and contract
- Current CMS billing guidance

Tired of second-guessing patient status?
Frequently Asked Questions
It is Medicare’s test for new versus established status at an FQHC. Any professional medical or mental health service from your organization, at any site, in the last three years? Then the patient is generally established. Nothing? Generally new.
G0466 is for a new patient. G0467 is for an established patient. Both assume the visit qualifies under the FQHC PPS.
No. Only new-patient, IPPE, and AWV visits receive it, and it is applied to the PPS rate.
Not automatically. State policy and your payer contracts determine the rules.
Yes. Nivaran’s CodeEMR offers CHC and FQHC coding, including medical and behavioral health, PPS, telehealth, and preventive services. AAPC- and AHIMA-certified coders handle the work.
Yes. It handles encounter-based and PPS coding for Medicare and Medicaid, including payer-specific requirements that vary by state and contract.
Final Takeaway
If you remember one thing, make it this: the 3-year rule is about the organization, not the provider. Has anyone at any of your sites given this patient professional medical or mental health care in the last three years? Start there. The visit, the documentation, the payment code, and the payer rules come next.
