This is Week 4 of the ClaimsXperts FQHC Billing Series. Week 1 covered the foundational FQHC billing model. Week 2 was a deep dive into the Medicare PPS. Week 3 covered Illinois Medicaid billing. This week focuses on FQHC credentialing — the HRSA scope of project, provider enrollment with Medicare and Medicaid, and the critically underutilized process of requesting a Medicaid PPS rate adjustment when your health center adds services or sites.
FQHC credentialing is unlike credentialing in any other healthcare setting. A hospital-based practice or a private specialty group manages physician and mid-level provider credentialing across a defined set of payers. An FQHC manages all of that — plus a parallel layer of organizational credentialing with HRSA, Medicare, and state Medicaid that must be kept current at the organization level before any individual provider credentialing can function correctly.
When an FQHC adds a new service — behavioral health, dental, vision, pharmacy — or opens a new service site, the operational workload is significant. But there is a financial dimension to these expansions that most health centers underutilize: the federal legal requirement that states provide a mechanism to adjust the Medicaid PPS encounter rate to reflect changes in the scope of services provided. Health centers that add high-cost services — behavioral health integration is the most common example — may be entitled to a meaningfully higher per-visit Medicaid rate. Centers that do not initiate the change in scope process continue receiving a rate that no longer reflects their actual cost of care.
This guide covers the full FQHC credentialing framework for 2026 — HRSA scope of project maintenance, the Change in Scope (CIS) process, Medicare PECOS enrollment for new sites, Medicaid enrollment requirements, individual provider credentialing within the FQHC, and the 2026 enrollment updates every health center needs to know.
FQHC Credentialing, Scope of Project & Medicaid PPS Rate Adjustments
Adding services or sites triggers two separate processes — HRSA scope approval and a Medicaid PPS rate adjustment. Most health centers complete the first and skip the second.
Part 1: Two Distinct “Scope” Concepts — A Critical Distinction
Before diving into process, the single most important conceptual clarification in FQHC administration:
“Change in scope of project” (HRSA) and “change in scope of services” (CMS/Medicaid) are two different things governed by two different bodies of law. They are related but not the same, and confusing them is one of the most common administrative errors in health center management.
HRSA Scope of Project
The HRSA scope of project defines what your health center is approved to do under your Section 330 grant or Look-Alike designation. It specifies:
- Service sites — the physical locations where HRSA-approved services are delivered
- Services — the types of health services you are authorized to provide (medical, dental, behavioral health, enabling services, pharmacy, vision, etc.)
- Target population — the communities you are designed to serve
- Providers — the types of providers delivering services within the approved scope
The scope of project is governed by HRSA under PIN 2008-01 and documented in the health center’s Notice of Award (NoA) for grantees or Notice of Look-Alike Designation (NLD) for Look-Alikes. Changes to the scope of project require HRSA approval through the formal Change in Scope (CIS) process.
Key rule from HRSA: Changes to the scope of project must be approved before the health center can claim Medicare and Medicaid reimbursement for services delivered at new sites or for new service types. Delivering services outside the HRSA-approved scope before CIS approval creates significant compliance risk.
CMS/Medicaid Change in Scope of Services
The CMS and state Medicaid definition of “change in the scope of services” is a separate, rate-adjustment mechanism. Under Section 702 of BIPA (Benefits Improvement and Protection Act of 2000), states are required to provide a mechanism for adjusting an FQHC’s Medicaid PPS encounter rate when there is a change in the type, intensity, duration, and/or amount of services the health center provides.
This is the rate-adjustment process that most health centers underutilize. It is distinct from the HRSA CIS process — though the two are often triggered together, since adding a HRSA-approved service (dental, behavioral health) often also constitutes a Medicaid change in scope that should trigger a rate adjustment request.
The practical implication: HRSA CIS approval alone does not automatically update your Medicaid PPS rate. You must separately notify your state Medicaid agency and initiate the PPS rate adjustment process.
Part 2: The HRSA Change in Scope (CIS) Process
When a CIS Is Required
A formal CIS submission to HRSA is required whenever the health center proposes to:
- Add a new service site — a new physical location where FQHC services will be delivered
- Change the type of service site — converting a mobile unit to a fixed site, or changing a seasonal site to a year-round site
- Add a new service type — adding dental, behavioral health, pharmacy, vision, enabling services, or other HRSA-recognized service categories not currently in scope
- Delete a service or site — discontinuing a service or closing a location
- Change the target population — significantly expanding or changing the communities served
- Significant changes in annual operating budget — additions exceeding a threshold percentage
The CIS Submission Process
Step 1 — Access the Health Center Program (HCP) Portal: All CIS submissions are made through the HRSA Health Center Program Portal at hrsa.gov/healthcenters. Grantees and Look-Alikes both submit CIS through this system.
Step 2 — Identify the CIS category: HRSA distinguishes between CIS that require prior approval (must be approved before the change is implemented) and notifications (submitted after the change). Adding a new service site or service type requires prior approval — these cannot be implemented before HRSA CIS approval is received.
Step 3 — Prepare required documentation:
- Notice of Proposed Change — detailed description of the proposed change
- Budget justification — how the change affects annual operating costs
- Site-specific information (for new sites) — address, operating hours, services to be provided, provider staffing plan
- Community needs justification — why this change is needed for the target population
Step 4 — Submit and await approval: HRSA reviews CIS submissions and issues either:
- An amended Notice of Award (NoA) for grantees
- An amended Notice of Look-Alike Designation (NLD) for Look-Alikes
Processing times vary — build a minimum of 60 to 90 days into project timelines for CIS approval. Do not initiate services at a new site or begin billing for a new service type before the amended NoA or NLD is received.
Part 3: Adding a New FQHC Site — Medicare Enrollment Through PECOS
Once HRSA approves a new service site through the CIS process, the health center must complete a separate Medicare enrollment for the new site before Medicare claims can be submitted.
PECOS Enrollment for New FQHC Sites
Health centers need to inform Medicare when adding new FQHC sites to scope by using the CMS electronic Provider Enrollment, Chain, and Ownership System (PECOS) or submitting a new Medicare Enrollment Application Form 855A to their Medicare Administrative Contractor. This is required to enroll any new service site that is approved by HRSA through the change in scope process or through a funded application. HRSA encourages health centers to enroll new sites through PECOS because it streamlines the process.
Required documentation for new FQHC site Medicare enrollment:
- The amended Notice of Award (NoA) or Notice of Look-Alike Designation (NLD) from HRSA documenting approval for the new site
- Completed Medicare Enrollment Application (through PECOS or Form 855A)
- Site-specific information — physical address, ownership structure, operating hours
- Staff NPIs for providers who will render services at the new site
Processing time for Medicare FQHC site enrollment: Typically 60 to 90 days from submission of a complete application to the MAC. Factor this into your new site opening timeline — claims submitted before Medicare enrollment is active for the site will be denied.
PECOS 2.0 — 2026 Update: The Medicare PECOS system is undergoing a significant upgrade in 2026. PECOS 2.0 is now the system of record for all Medicare enrollment submissions, following an AWS Cloud migration in 2026. Health centers submitting new site enrollments or making changes to existing enrollment records should confirm they are using the PECOS 2.0 interface and that any IP allowlists in their network infrastructure have been updated to accommodate the new cloud infrastructure.
2026 Medicare Enrollment Policy Changes — Retroactive Revocation Authority
The CY 2026 Medicare Final Rule introduced important enrollment policy changes that affect FQHCs:
- Retroactive revocation authority: CMS now has authority to retroactively revoke Medicare enrollment in certain circumstances. This means an FQHC could face retroactive revocation — and requirement to repay previously received Medicare payments — if enrollment requirements were not met correctly
- 30-day adverse legal action reporting: FQHCs must now report adverse legal actions (professional license sanctions, felony convictions, etc.) within 30 days — down from the prior reporting window. Build a compliance monitoring system to ensure adverse action reporting occurs within this shortened window
- 12-month inactivity deactivation: Medicare enrollment can be deactivated if the FQHC site has been inactive (submitted no claims) for 12 consecutive months. Monitor all site-level claim activity and reactivate dormant sites promptly if they resume operations
State Medicaid Enrollment for New Sites
Many state Medicaid programs require new sites to enroll individually and bill for services using a site-specific NPI.
After Medicare enrollment, the health center must also enroll the new site with state Medicaid and all relevant MCOs. State Medicaid requirements for new FQHC sites vary — confirm your state’s specific process with your state Medicaid agency. Most states require:
- A site-specific NPI for the new location
- Updated enrollment records reflecting the new site address
- MCO roster updates to add the new site’s providers and NPI to each MCO’s network
Part 4: Adding New Services — How It Affects Your Medicaid PPS Rate
This is the most financially significant and most underutilized aspect of FQHC administration. When a health center adds a new service to its HRSA scope — behavioral health, dental, pharmacy, vision — the cost per visit typically increases meaningfully. Federal law requires states to provide a mechanism to adjust the Medicaid PPS rate to reflect this change.
The Federal Legal Requirement
Federal law requires states to provide mechanisms to adjust FQHC per visit rates to reflect changes in the scope of services provided by FQHCs during the year in which those changes took place.
This is not discretionary. States must have a process for adjusting FQHC Medicaid PPS rates when a change in scope occurs. A health center that adds behavioral health services and does not request a PPS rate adjustment is leaving legally available revenue uncollected — potentially for years, because the rate remains fixed at the pre-expansion level until a change in scope request is submitted and processed.
What Constitutes a Medicaid Change in Scope of Services
CMS and state Medicaid agencies define the term “change in the scope of services” as a mechanism for adjusting the Medicaid reimbursement rate of a FQHC due to “a change in the type, intensity, duration and/or amount of services.”
Common triggers for a Medicaid PPS rate adjustment through the change in scope process:
Adding a new service type that increases per-visit cost:
- Adding behavioral health services (most common and highest-impact trigger)
- Adding dental services as an FQHC service
- Adding pharmacy services
- Adding enabling services (transportation, translation, case management) at significant scale
Adding a new site that serves a higher-acuity population:
- A new site in a higher-cost geographic area
- A site serving a population with significantly more complex medical needs
Expanding hours or visit intensity:
- Significant expansion of after-hours or weekend services
- Adding extended visit time for complex patient populations
Important distinction from HRSA CIS: A “change in scope of project” under Section 330 is not the same as “change in the scope of services” in Medicaid as defined in BIPA of 2000, Section 702.
The Medicaid change in scope mechanism is separately managed by the state Medicaid agency — not by HRSA. A health center that obtains HRSA CIS approval for behavioral health services has NOT automatically initiated the Medicaid PPS rate adjustment process. That is a separate step with the state Medicaid agency.
What Does NOT Trigger a Medicaid PPS Rate Adjustment
An increase or decrease of provider’s costs does not constitute a change in scope of services.
Simply spending more money — higher staff salaries, renovations, equipment purchases — without a change in the type, intensity, duration, or amount of services does not qualify for a PPS rate adjustment. The change must be in what you do and who you serve, not just what it costs to operate.
How the New Rate Is Calculated
When a state approves a Medicaid PPS rate adjustment based on a change in scope:
- The health center submits a new cost report reflecting its costs after the scope change
- The state calculates a new per-visit rate based on allowable costs per qualifying visit
- The new rate is implemented prospectively — it does not typically apply retroactively to visits prior to the rate adjustment approval
- The rate is updated annually for inflation using the Medicare Economic Index or state-specific inflation measure
The financial impact can be significant. Adding behavioral health services to a primary care FQHC typically increases the average cost per qualifying visit by 15–30%, because behavioral health visits are time-intensive and require licensed clinical professionals. If the Medicaid PPS rate is not adjusted, the health center absorbs all of this additional cost without corresponding revenue — widening the gap between actual cost and Medicaid reimbursement for every visit.
Part 5: Individual Provider Credentialing at FQHCs
The FQHC-Specific Provider Credentialing Requirement
FQHCs have a distinct set of provider credentialing requirements compared to private practices. Every clinical provider rendering services at an FQHC must be:
- Credentialed and privileged at the FQHC organizational level — through the health center’s credentialing committee and peer review processes
- Enrolled in Medicare under their own individual NPI — with the FQHC listed as their employer/practice location
- Enrolled in state Medicaid — in most states through the state’s provider enrollment portal
- Credentialed with each MCO that serves the FQHC’s patient population
- Listed on the FQHC’s HRSA scope of project if they are a qualifying FQHC practitioner type
Qualifying FQHC Practitioners — Who Can Render Billable Encounters
For Medicare purposes, encounters are only billable when rendered by a qualifying FQHC practitioner. As covered in Week 2, these include physicians (MD/DO), physician assistants (PA), nurse practitioners (NP), certified nurse midwives (CNM), clinical psychologists (CP), clinical social workers (CSW), and visiting nurses.
Non-qualifying practitioners at FQHCs: Medical assistants, licensed vocational nurses, and other staff below the qualifying practitioner level cannot generate billable FQHC encounters under Medicare or most state Medicaid programs, even when rendering services under a qualifying practitioner’s supervision. Build this into your staffing and billing workflow — services rendered by non-qualifying practitioners are not separately billable under the FQHC encounter model.
Provider Enrollment Timeline at FQHCs
For new FQHC providers, the complete enrollment sequence is:
| Step | Action | Timeline |
|---|---|---|
| 1 | HRSA scope update (if new provider type not in scope) | 60–90 days |
| 2 | Medicare PECOS enrollment — individual NPI linked to FQHC site | 60–90 days |
| 3 | State Medicaid enrollment | 30–60 days |
| 4 | MCO credentialing — each MCO separately | 60–90 days per MCO |
| 5 | FQHC internal credentialing and privileging — committee review | 30–60 days |
All steps may run concurrently — but Medicare and Medicaid enrollment must be active before the first billable encounter is submitted. For complex situations (new provider type, new service requiring HRSA CIS), build 120 to 150 days into the onboarding timeline before the provider begins generating billable encounters.
2026 FQHC Provider Enrollment Considerations
PECOS 2.0 and FQHC provider enrollments: All individual provider Medicare enrollments linked to FQHC sites must be managed through PECOS 2.0 in 2026. Ensure your enrollment team is using the current PECOS interface and that all FQHC site associations are correctly linked in the new system.
Adverse action monitoring — 30-day reporting: The 2026 requirement to report adverse legal actions within 30 days applies to individual FQHC providers as well as the organizational enrollment. FQHCs with large provider rosters should implement an automated monitoring system for professional license sanctions, exclusion database entries, and adverse legal actions — the 30-day window requires near-real-time awareness.
Medicare enrollment application fee: The 2026 Medicare enrollment application fee is $750 per institutional provider location for FQHCs submitting new site enrollments. For health centers opening multiple new sites in a single year, factor this fee into the expansion budget.
Part 6: Maintaining Accurate Scope — Ongoing Compliance Requirements
Annual and Ongoing HRSA Reporting
FQHCs must file the Uniform Data System (UDS) report annually — by February 15 of each year for the prior calendar year. The UDS captures patient visits, services provided, providers, sites, and financial performance. UDS data must accurately reflect the health center’s current scope of project — any services or sites operating outside the approved scope create compliance exposure.
Common HRSA scope maintenance errors:
- Delivering services at a location not listed in the approved scope (off-scope site)
- Providing a service type not included in the approved scope (off-scope service)
- Significant changes in staffing, budget, or services without CIS notification
- UDS data that reflects different services than the approved NoA
Revalidation Requirements
Both Medicare and Medicaid require periodic revalidation of FQHC enrollment:
- Medicare revalidation: Every 5 years (institutional providers) — PECOS sends notification approximately 6 months before the deadline
- State Medicaid revalidation: Frequency varies by state — typically every 3 to 5 years
Missed revalidation deadlines result in deactivation of billing privileges. Build revalidation deadline tracking into your compliance calendar — a deactivated Medicare enrollment means no Medicare claims can be submitted until reactivation is complete.
MCO Quarterly Directory Attestation
Under the Consolidated Appropriations Act 2021 (CAA 2021), health centers must attest quarterly that their provider directory information is accurate with each MCO. Failure to attest can result in removal from the MCO provider directory — which affects patient access and eligibility for in-network billing.
Part 7: 2026 FQHC Credentialing Updates
1. CY 2026 Tribal FQHC PPS Rate Update (CMS CR 14349)
CMS Change Request 14349, effective January 1, 2026 and implemented March 6, 2026, updated the payment rate for historically excepted Tribal FQHCs under the Prospective Payment System. Tribal FQHCs operating under the historically excepted rate structure should confirm their updated 2026 payment rate with their MAC (Medicare Administrative Contractor).
2. PECOS 2.0 — System of Record for All Enrollments
PECOS 2.0 is now the system of record for all Medicare enrollment submissions following the 2026 AWS Cloud migration. FQHCs using any IP allowlist-based security for their network infrastructure should confirm PECOS 2.0 connectivity with their IT team. Old PECOS login credentials and saved workflows may not carry over to the new system.
3. 30-Day Adverse Legal Action Reporting
Effective 2026, all adverse legal actions affecting FQHC providers or the organization itself must be reported to CMS within 30 days. Build proactive monitoring into your compliance workflow:
- License verification through state licensing boards (monthly recommended)
- OIG LEIE (exclusion database) checks (monthly for all providers)
- SAM.gov debarment checks (monthly)
- State Medicaid exclusion list checks (monthly)
4. 12-Month Inactivity Deactivation
FQHCs with satellite or seasonal sites that have submitted no Medicare claims for 12 consecutive months may have their site-level Medicare enrollment deactivated. Run a quarterly claim activity report by site to identify any site approaching the 12-month inactivity threshold and submit activity or initiate reactivation before deactivation occurs.
What Your FQHC Should Do Right Now
HRSA scope of project:
- Pull your current Notice of Award or Notice of Look-Alike Designation — confirm it accurately reflects all sites currently delivering services and all service types currently being provided
- If any site or service has been added without a CIS submission and HRSA approval, consult with your health center attorney about remediation options
- Review your UDS report for consistency with your approved scope — discrepancies between UDS data and the NoA are a primary trigger for HRSA compliance reviews
Medicaid PPS rate adjustment:
- Inventory every service your health center has added since your last Medicaid PPS rate adjustment — behavioral health, dental, enabling services, pharmacy, vision
- If you have added services without requesting a Medicaid PPS rate adjustment, contact your state Medicaid agency to initiate the change in scope process
- Prepare a cost report that reflects your post-expansion cost structure — this is the basis for the new rate calculation
- Do not wait for your state to notice the scope change — the rate adjustment must be requested by the health center, not initiated by the state
Medicare PECOS and enrollment:
- Confirm all service sites are correctly enrolled in PECOS 2.0 with current address, operating status, and provider associations
- Verify no sites are approaching the 12-month inactivity deactivation threshold
- Implement a 30-day adverse action monitoring workflow for all providers
- Budget $750 per new institutional site enrollment for the 2026 Medicare application fee
Provider enrollment and credentialing:
- Build a 120–150 day onboarding timeline for new FQHC providers requiring full enrollment and credentialing
- Implement quarterly MCO provider directory attestations for all MCOs serving your patient population
- Confirm all individual provider PECOS enrollments are correctly linked to the appropriate FQHC site(s)
- Add Medicare revalidation and state Medicaid revalidation deadlines to your compliance calendar
Final Thoughts
FQHC credentialing is not a one-time event — it is an ongoing administrative function that directly affects the health center’s ability to bill, its Medicaid reimbursement rate, and its HRSA compliance status. Health centers that maintain accurate scope, proactively request Medicaid PPS rate adjustments when adding services, and keep Medicare and Medicaid enrollment current for all sites and providers are consistently better positioned financially and compliance-wise than those that treat credentialing as an annual checkbox.
The Medicaid PPS rate adjustment process is the single largest missed revenue opportunity in health center administration. A center that added behavioral health services three years ago and has not yet submitted a change in scope request to its state Medicaid agency is being reimbursed at a rate that no longer reflects its cost of care — for every Medicaid encounter, every month, compounding.
