Most brokers who work near the Medicaid income threshold get the call eventually. A client's income went up, the state Medicaid agency terminated their coverage, and now they have no insurance and a 60-day window to enroll on the Marketplace before it closes. The brokers who catch this before the termination date have the full 60 days. The ones who get the call two weeks after the termination date are working with a narrower window and a client who is already uninsured.
Key Takeaways
- Loss of Medicaid or CHIP coverage triggers a 60-day Special Enrollment Period on the ACA Marketplace. The SEP is classified under loss of qualifying coverage under 45 CFR 155.420(d)(1).
- The 60-day window starts from the date coverage ends, not from notice of termination. A client whose Medicaid terminates on June 30 has until August 29 to select a Marketplace plan.
- Clients who lose Medicaid because their income rose above the eligibility threshold are often APTC-eligible on the Marketplace, assuming they are in an expansion state and above 100 percent FPL.
- In the 10 non-expansion states still as of 2026, a client below 100 percent FPL who loses Medicaid for administrative reasons does not qualify for Marketplace APTC. There is no coverage path in these states below that income floor without expansion.
- Brokers who represent clients near the Medicaid threshold should document the exact termination date from the state agency notice, not from the client's memory of when care was denied.
What triggers the SEP
Loss of Medicaid or CHIP coverage is a qualifying life event under 45 CFR 155.420(d)(1). When a client's Medicaid is terminated for any reason, including income increase, administrative redetermination, or aging out of a child eligibility category, a 60-day SEP opens on the federal Marketplace or the applicable state-based exchange.
The SEP is triggered by the loss of coverage, not by the loss of eligibility. A client who receives a notice in June that their Medicaid will terminate July 31 does not have an SEP open in June. The SEP opens August 1, when coverage ends. The 60-day window runs from that date. Brokers who mistake the notice date for the trigger date miscalculate the enrollment window and may tell a client they have more time than they do, or less.
The income question and what follows
Why income matters: the path from Medicaid to the Marketplace is only smooth when the client's income lands in the APTC range.
| Client scenario | Income | State type | Outcome |
|---|---|---|---|
| Income rises above Medicaid threshold | 100 to 138% FPL (expansion) | Expansion state | Qualifies for Marketplace APTC. SEP opens on loss of Medicaid. APTC typically available. |
| Income rises above Medicaid threshold | 138 to 400%+ FPL | Any state | Qualifies for Marketplace APTC. SEP opens on loss of Medicaid. Strong subsidy at lower end of range. |
| Administrative termination, income unchanged | At or below state threshold | Expansion state | Qualifies for Marketplace with APTC if income is above 100% FPL. Should re-apply for Medicaid and use Marketplace SEP as a bridge. |
| Income below 100% FPL | Below 100% FPL | Non-expansion state | Coverage gap. No Marketplace APTC below 100% FPL in non-expansion states. No Medicaid in most non-expansion states at this income. No coverage path. |
Illustrative scenarios. Medicaid eligibility thresholds vary by state. FPL percentages are based on the 2026 federal poverty guidelines. Non-expansion state count reflects status as of 2026. Verify current state Medicaid thresholds directly with the state agency.
The critical boundary in expansion states is 100 percent FPL. A client above that threshold who loses Medicaid coverage lands in the APTC range. For a single adult in 2026, 100 percent FPL is approximately $15,060. For a family of four, it is approximately $31,200. Clients right at this boundary can have subsidy eligibility that is sensitive to small income fluctuations. The broker who understands where the client's income actually sits in relation to the FPL boundary prevents an enrollment mistake.

The non-expansion gap: a different problem
Ten states had not expanded Medicaid as of 2026. In these states, the income floor for Marketplace APTC is 100 percent FPL, but the state Medicaid program typically covers adults only at very low income levels or not at all for non-disabled, non-pregnant adults without dependents. A client who loses Medicaid in one of these states and has income below 100 percent FPL has no ACA-subsidized option available. Neither program serves them.
This is not a broker error and it is not a Marketplace enrollment problem. It is a gap created by the 2012 Supreme Court decision making Medicaid expansion optional for states, which the ACA's drafters had not anticipated. Community health centers, which operate on sliding-scale fees funded by federal grants independent of the ACA, are often the most practical referral for clients in this situation. For a full explanation of how the gap works and which states are affected, read the ACA coverage gap in non-expansion states.
Platforms and EDE workflows
GetInsured, which operates an EDE platform, includes Medicaid eligibility screening as part of its enrollment flow and can electronically hand off applicants to state Medicaid agencies when income falls below the APTC range. For brokers who do not use EDE platforms, the Medicaid-to-Marketplace transition is a manual workflow: the broker must identify that the SEP is open, document the termination date, run APTC math against the client's current income, and submit the Marketplace application within the 60-day window.
The income number used for the Marketplace application should be the client's current projected annual income, not the income that triggered the Medicaid redetermination (which may have been reported to the state on a different schedule). These can differ, particularly for clients with variable self-employment income. Getting this right at intake prevents an APTC miscalculation and a surprise.
Building the proactive workflow
The broker who calls before the termination date has the most options. Medicaid redetermination cycles are predictable: most states conduct annual renewals at the client's anniversary date. States that conducted redeterminations during the 2023 to 2024 unwinding period are now running annual cycles again.
Practical steps for brokers with Medicaid-adjacent clients:
First, flag clients whose reported income is within 20 percent of the state Medicaid threshold. Income variation in gig work, freelance, or seasonal employment can push these clients above the threshold without warning.
Second, ask clients to share any state Medicaid redetermination notices before the annual review date. Many clients ignore these notices until coverage is already gone.
Third, document the exact coverage termination date from the state agency, not from the client's memory. The 60-day window has no exceptions and no extensions. For the full SEP trigger list and documentation requirements, read how brokers handle SEP qualifying life events.
FAQ
Questions brokers frequently encounter when a client loses Medicaid and transitions to the Marketplace.
How long does a client have to enroll on the Marketplace after losing Medicaid?
60 days from the date Medicaid coverage ends. The window does not extend from the date the client receives notice, the date the broker is contacted, or the date the client confirms the loss. It runs from the termination date on the Medicaid record. A client who loses Medicaid coverage on July 15 has until September 13 to select a Marketplace plan through the SEP. After that date, without a new qualifying event, the client must wait until the next OEP.
What documentation does the Marketplace require to use the loss-of-Medicaid SEP?
The Marketplace requests verification that the client had Medicaid coverage that terminated. Acceptable documentation includes a letter from the state Medicaid agency stating the coverage end date, an explanation of benefits from a period when Medicaid was active, or a written confirmation of disenrollment from the state agency. Some state-based exchanges pre-verify Medicaid status through data matching with the state Medicaid agency, which can simplify the process. On the Federal Marketplace, the application typically flags the SEP reason, and the Marketplace may initiate its own verification or send the client a data-matching notice.
Can a client be enrolled in Medicaid and receive Marketplace APTC at the same time?
No. A client enrolled in Medicaid is not eligible for APTC during the months of Medicaid enrollment. APTC is only available for months the client is enrolled in a Marketplace plan and does not have other minimum essential coverage available. Once Medicaid terminates, the client is eligible for APTC on the Marketplace going forward. The two programs do not run concurrently, and APTC paid for months where the client had Medicaid must be reconciled on Form 8962.
What if a client loses Medicaid because of an error, not a genuine income change?
The SEP still opens from the date Medicaid coverage terminated, regardless of the reason for termination. The client should simultaneously pursue reinstatement of Medicaid with the state agency and use the Marketplace SEP to get coverage in place quickly. If Medicaid is reinstated retroactively, the client will need to disenroll from the Marketplace plan for the overlapping months to avoid APTC recapture on Form 8962. The reinstatement and Marketplace enrollment timelines often do not align cleanly, and brokers who handle this scenario should document every date carefully.
In a non-expansion state, what options exist for a client below 100 percent FPL who loses Medicaid?
Very few options exist within the ACA framework. APTC requires income at or above 100 percent FPL. Clients below that threshold in non-expansion states fall into the coverage gap that resulted from the Supreme Court's 2012 decision making Medicaid expansion optional. Some non-expansion states offer limited state-funded coverage programs, community health centers operate on sliding-scale fees and are funded independently of ACA, and some clients may qualify for CHIP if they have dependents under 19. Brokers in non-expansion states working near this income boundary should be familiar with the gap before the enrollment conversation, not during it.
