Healthcare providers that serve Medicaid and CHIP patients should pay close attention to upcoming eligibility changes connected to Section 71109 of the Working Families Tax Cut legislation. CMS released implementation guidance to help Medicaid and CHIP agencies prepare for these changes, which become applicable on and after October 1, 2026.
For medical practices, hospitals, clinics, and billing teams, this update is not just a policy issue. It can directly affect eligibility verification, prior authorization, claim submission, patient communication, denials, and accounts receivable. Providers that treat Medicaid and CHIP patients should begin reviewing their workflows early so they are not surprised by coverage changes or preventable claim denials.
What Is Section 71109?
Section 71109 is a federal Medicaid and CHIP eligibility provision related to certain noncitizen eligibility rules. According to CMS guidance, beginning October 1, 2026, federal financial participation for non-emergency Medicaid and certain CHIP benefits will generally be limited to specific groups, as long as the individual meets all other eligibility requirements.
These groups include:
- U.S. citizens
- U.S. nationals
- Lawful permanent residents, also known as green card holders
- Cuban/Haitian entrants
- Compacts of Free Association migrants, also known as COFA migrants
CMS refers to lawful permanent residents, Cuban/Haitian entrants, and COFA migrants as FFP-eligible noncitizens.
This means state Medicaid and CHIP agencies will need to review certain current beneficiaries and determine whether they continue to qualify for full Medicaid or CHIP benefits under the updated federal funding rules.
When Do the New Medicaid Eligibility Rules Start?
The key date for providers to know is October 1, 2026.
CMS guidance states that Section 71109 applies on and after October 1, 2026. States must not limit full Medicaid or CHIP benefits based on this new rule before that date. This means providers should not assume that coverage changes are already active before October 2026.
However, state Medicaid agencies will need to prepare in advance. CMS guidance says states must treat the change as a change in circumstance for current beneficiaries and redetermine eligibility for potentially affected populations by October 1, 2026.
For providers, this creates an important preparation window. Billing teams, front desk teams, and eligibility verification teams should begin reviewing their Medicaid workflows before the effective date.
Which Medicaid and CHIP Benefits Are Affected?
The CMS guidance explains that the limitation applies to full Medicaid and CHIP benefits, as well as certain partial or limited Medicaid benefits. This may include coverage groups such as:
- Categorical Medicaid groups
- Medically needy groups
- Supplemental Security Income recipients
- Foster care children
- Other children and adults
- Dually eligible individuals
- Medicare Savings Program beneficiaries
- Individuals receiving limited non-emergency Medicaid benefits, such as family planning services only
The guidance also notes that emergency Medicaid is treated differently. The rule does not apply to Medicaid coverage for care and services necessary to treat an emergency medical condition.
This distinction matters for providers because a patient may still have some Medicaid coverage, but not necessarily full coverage for every type of service.
What Are the Main Exceptions?
CMS identifies three main exceptions to the federal funding limitation under Section 71109.
The first exception is emergency Medicaid. Medicaid coverage for emergency medical conditions is not treated the same way as full non-emergency Medicaid coverage.
The second exception is coverage under the CHIPRA 214 option. In states that have elected this option, certain lawfully residing children and pregnant women may remain eligible for Medicaid or CHIP coverage.
The third exception is Health Services Initiatives, also known as HSIs, under CHIP authority.
Because Medicaid and CHIP rules can vary by state, providers should monitor state Medicaid agency updates and not rely only on general national summaries.
Why This Matters for Healthcare Providers
Eligibility changes can create billing problems if providers are not prepared. Even if the change is handled by the state Medicaid agency, the impact can reach the provider’s revenue cycle.
If coverage changes are missed at the front end, providers may see problems such as:
- Denied claims
- Eligibility-related rejections
- Prior authorization issues
- Patient balance confusion
- Retroactive coverage questions
- Increased accounts receivable
- Delayed reimbursement
- More billing team follow-up
- Higher administrative workload
For practices that see a large Medicaid population, this can become a serious operational issue. Primary care, pediatrics, OB/GYN, behavioral health, urgent care, community health clinics, specialty practices, and hospital-based providers should all review how these changes may affect their patients.
How States Will Redetermine Current Beneficiaries
CMS guidance outlines a process that states should follow when reviewing current Medicaid and CHIP beneficiaries who may be affected.
First, states must identify potentially affected beneficiaries. These are generally beneficiaries who are not U.S. citizens or nationals and whose immigration status is not one of the statuses listed as FFP-eligible under the new rule.
Second, states must use information already in the beneficiary record to determine whether the beneficiary continues to have satisfactory immigration status.
Third, states must attempt to verify immigration status electronically through the Department of Homeland Security’s SAVE program before contacting the beneficiary.
Fourth, if electronic verification does not confirm satisfactory immigration status, the state must request additional information from the beneficiary and provide a reasonable amount of time to respond.
Fifth, if needed, the state must provide a 90-day reasonable opportunity period when the beneficiary has declared U.S. citizenship, U.S. national status, or satisfactory immigration status and the state cannot promptly verify that status.
Finally, before reducing or terminating coverage, states must consider all bases of eligibility and provide proper notice of adverse action.
For providers, the most important point is simple: some patients may go through a redetermination process before October 1, 2026, and coverage status may change depending on the outcome.
What This Means for Eligibility Verification
Eligibility verification will become even more important as the October 2026 effective date gets closer.
Providers should not only check whether Medicaid is active. They should also check the type of coverage, benefit limitations, payer response details, and whether the service is covered under the patient’s current eligibility category.
A basic active or inactive response may not be enough. Billing teams should review eligibility responses carefully and confirm whether the patient has full Medicaid, limited benefits, emergency-only coverage, CHIP coverage, managed care enrollment, or another coverage category.
Strong eligibility verification can help prevent avoidable claim denials and reduce confusion after services are provided.
Steps Providers Should Take Before October 2026
Healthcare providers should begin preparing now instead of waiting until the rule takes effect.
- Here are practical steps practices can take:
- Review Medicaid eligibility verification workflows
- Verify coverage before each visit
- Check benefit type, not only active status
- Confirm prior authorization requirements
- Train front desk staff on Medicaid coverage changes
- Train billing staff to review Medicaid eligibility responses carefully
- Monitor state Medicaid agency updates
- Track eligibility-related denials
- Update patient communication scripts
- Review policies for emergency Medicaid and limited coverage
- Document eligibility verification results in the EHR or billing system
- Review Medicaid managed care payer requirements
- Create an internal escalation process for unclear eligibility responses
These steps can help reduce claim delays and prevent services from being billed under incorrect assumptions.
How This May Affect Prior Authorization
Prior authorization workflows may also be affected by Medicaid eligibility changes. If a patient’s coverage changes, an authorization that was previously valid may need to be reviewed. Some services may require a new authorization, while other services may no longer be covered under the patient’s updated benefit category.
Providers should verify eligibility before requesting authorization and again before the date of service. This is especially important for high-cost services, recurring treatment plans, surgeries, imaging, specialty care, therapy, and procedures that require payer approval.
A clean prior authorization process should include both coverage verification and benefit review.
How This May Affect Claims and Denials
If a Medicaid or CHIP patient’s eligibility changes, claims that were previously payable may be denied or processed differently. Providers may see denials related to:
- Inactive coverage
- Coverage terminated before the date of service
- Limited benefits
- Service not covered under benefit category
- Prior authorization missing or invalid
- Patient not eligible on date of service
- Incorrect payer billing
- Medicaid managed care mismatch
- Emergency-only coverage limitations
To manage this risk, practices should track denial trends by payer, denial reason, date of service, patient coverage category, and service type. This helps identify whether the issue is isolated or part of a larger eligibility change.
Impact on Accounts Receivable
Eligibility-related denials often create additional accounts receivable work. Billing teams may need to contact the payer, check state Medicaid portals, review eligibility history, correct payer information, appeal when appropriate, or communicate with the patient.
If practices are not prepared, these claims can sit in A/R for weeks or months. This delays payment and increases administrative cost.
A proactive revenue cycle process should include:
- Eligibility checks before service
- Claim review before submission
- Denial tracking after adjudication
- Fast follow-up on Medicaid denials
- Clear documentation of payer responses
- Patient communication when coverage changes
This helps protect cash flow and reduce avoidable write-offs.
What About Emergency Medicaid?
CMS guidance notes that emergency Medicaid is not subject to the same limitation as full non-emergency Medicaid coverage. For providers, this means emergency services may still be covered under emergency Medicaid rules when the patient meets the applicable requirements.
However, emergency Medicaid is not the same as full Medicaid coverage. Providers should avoid assuming that emergency-only coverage will pay for all services. Billing teams should carefully review whether the service qualifies under emergency Medicaid rules and whether the state Medicaid program has specific billing requirements.
What About CHIP?
CHIP rules may also be affected, especially for child and pregnancy-related health assistance. CMS guidance states that coverage under the CHIPRA 214 option is one of the key exceptions.
In states that have elected the CHIPRA 214 option, certain lawfully residing children and pregnant women may continue to qualify for coverage. However, because CHIP program rules can vary by state, providers should review state-specific updates.
Practices that see pediatric patients or pregnant patients should pay special attention to CHIP eligibility responses, managed care enrollment, and state Medicaid notices.
What Providers Should Tell Their Teams
This update should be explained clearly to front desk, billing, and clinical operations teams.
A simple internal message could be:
Medicaid and CHIP eligibility rules are changing on October 1, 2026. Some patients may go through eligibility redetermination before that date. We need to carefully verify Medicaid eligibility, coverage type, benefits, and prior authorization requirements before services are provided. If coverage looks limited, unclear, or changed, the issue should be escalated before the claim is submitted.
This type of staff training can help reduce confusion and prevent avoidable billing mistakes.
Why Front-End RCM Matters More Than Ever
Many billing problems begin before the claim is submitted. If eligibility is not verified correctly, the claim may be denied later, even if the service was medically necessary.
That is why front-end revenue cycle management is so important. Strong front-end processes include:
- Patient registration accuracy
- Insurance verification
- Benefit verification
- Medicaid eligibility review
- Prior authorization checks
- Referral checks
- Patient responsibility review
- Accurate demographic entry
- Payer portal documentation
When these steps are handled correctly, claims are more likely to go out clean the first time.

Final Thoughts
Section 71109 introduces important Medicaid and CHIP eligibility changes that become applicable on and after October 1, 2026. While state Medicaid agencies will handle the official redetermination process, providers should prepare their own billing and eligibility workflows now.
The biggest risk for healthcare providers is not just the policy change itself. The bigger risk is missing coverage changes at the front desk, submitting claims without proper eligibility review, and discovering the issue only after payment is denied.
By strengthening eligibility verification, prior authorization, denial management, and A/R follow-up, providers can reduce avoidable revenue loss and keep their billing process more stable during this transition.
