Updated and sources reviewed: October 7, 2026
An ACA Special Enrollment Period can help a client replace lost coverage, insure a newborn, respond to a move, or resolve an enrollment problem outside annual Open Enrollment. The useful starting point is a short set of facts: what happened, who was affected, when it happened, and when replacement coverage is needed.
For 2027, agents also need to distinguish final regulations from the rules CMS is implementing after court decisions. Some announced changes are on hold. Other changes—including the continued removal of the former monthly low-income SEP—remain relevant. CMS
This guide uses HealthCare.gov and the federal Marketplace platform as its operational baseline. State Marketplace differences are identified separately. Use the tables to screen a case, then confirm the applicable Marketplace’s eligibility determination, notices, and deadlines before promising enrollment or a start date.
1. What agents need to know about ACA SEPs for 2027
The 2027 rule-status table
| Topic | Status as of October 7, 2026 | Agent action |
|---|---|---|
| Former 150% FPL monthly SEP | The 2027 final rule continues its removal beyond 2026. Low income alone does not reopen that pathway. | Screen for a qualifying event, a specific eligibility-change SEP, Medicaid/CHIP, or an applicable state program. |
| Expanded pre-enrollment SEP verification and the 75% requirement | Stayed. CMS says existing loss-of-coverage SEP verification is unaffected. | Follow the client’s actual document request. Keep event evidence without assuming every SEP now faces a new verification requirement. |
| Federal Open Enrollment after the court decisions | CMS confirms November 1, 2026–January 15, 2027. | Use the dates below when explaining enrollment and coverage start dates. |
| HHS-created consent/application-review form | Required for enrollments for plan years beginning on or after January 1, 2028. | Continue meeting existing consent and application-review requirements for 2027; distinguish the future form requirement from current platform authorization controls. |
These distinctions follow CMS’s final-rule summary and its later implementation statement addressing the court decisions. CMS
Keep the status date with this table. A final-rule summary or training slide may describe a provision that later guidance changed. For the stayed provisions above, consult CMS’s August 4 implementation statement and subsequent instructions.
Federal Open Enrollment dates for 2027 coverage
| Date | What it means on HealthCare.gov |
|---|---|
| November 1, 2026 | Open Enrollment begins for 2027 coverage. |
| December 15, 2026 | Normal deadline to select a plan for January 1, 2027 coverage. |
| January 15, 2027 | Open Enrollment ends; selections from December 16 through January 15 generally start February 1, 2027. |
Payment and enrollment completion requirements still apply. State Marketplaces may use different dates. HealthCare.gov
A recent operational update belongs in your 2027 workflow
CMS’s September 22, 2026 announcement says agent-assisted applications must include verifiable Social Security numbers or immigration document numbers for non-newborn applicants. It also announces electronic consumer authorization before an agent can act on an application or enrollment, with implementation planned ahead of Open Enrollment. CMS
Practical response: check the current approved enrollment platform’s instructions before assisting the client. Build time into the appointment for identity and authorization steps, and resolve application errors through the supported process.
The announcement’s electronic authorization control is separate from the HHS-created documentation form required for 2028 plan-year enrollments.
Enrollment eligibility and financial help need separate review
Starting January 1, 2027, HealthCare.gov says federal savings for noncitizens are limited to qualifying lawful permanent residents, Cuban or Haitian entrants, and Compact of Free Association migrants. Other immigration statuses may still qualify for Marketplace coverage without federal savings. These categories do not establish eligibility by themselves; the other eligibility requirements still apply. HealthCare.gov
An agent reviewing a status change should therefore answer three questions separately:
- Can this person enroll?
- Does an enrollment period apply?
- What financial help is available for this coverage year?
2. Start every SEP review with six questions
Use these questions before selecting an event in the application:
- Which Marketplace serves the client? Confirm the state and whether enrollment uses HealthCare.gov or a state platform.
- Who needs coverage? Identify each affected household member. One person’s change can have different consequences for other people on the application.
- What actually changed? Record the event in the client’s own words, then determine the relevant enrollment pathway.
- What are the dates? Distinguish the event date, final covered day, notice date, and date replacement coverage is needed.
- What coverage existed before the event? Identify the coverage type and any prior-coverage requirement or exception.
- What result is the client seeking? Initial enrollment, adding a dependent, changing plans, obtaining financial help, and correcting an error require different decisions.
A useful intake question is:
“Tell me what changed, when your current coverage ends or ended, and who needs insurance. Then we can check the enrollment opportunity and the earliest available start date.”
Treat this as an intake framework. The Marketplace makes the eligibility determination.
3. Common ACA SEPs: an agent desk reference
The windows below concern plan selection. Requested-document and premium deadlines are separate.
| Client situation | Enrollment window to check | Facts to establish |
|---|---|---|
| Loss of qualifying health coverage | Generally 60 days before or after loss. | Affected person, actual coverage end date, and reason coverage ended. Include loss of employer coverage or dependent eligibility. |
| Loss of Medicaid or CHIP | On HealthCare.gov, 60 days before or 90 days after loss. | Confirm the person actually had coverage. Obtain the state notice and last covered day. |
| Marriage | Generally 60 days after marriage. | At least one spouse generally needs qualifying prior coverage for at least one day in the preceding 60 days; exceptions apply. |
| Birth, adoption, foster placement, or qualifying court order | Generally 60 days after the event. | Identify the new household member and event date. Event-date coverage can be available. |
| Permanent move | Generally 60 days after the move; advance availability varies by Marketplace. | Confirm access to new plans and the required prior coverage or exception. A vacation does not qualify. |
| COBRA exhaustion or complete end of employer/government premium support | Check the applicable 60-day before/after window and triggering date. | Distinguish exhaustion or a qualifying contribution-ending event from voluntary cancellation. |
| New access to an ICHRA or QSEHRA | Start with the employer notice and first availability date. The ordinary window is 60 days before availability; a notice-related exception can extend it afterward. | Confirm the deadline with the Marketplace and coordinate the arrangement’s start, individual coverage, and subsidy eligibility. |
| Divorce, separation, or death causing coverage loss | Check the loss-of-coverage window. | Determine whose insurance ended. These life events are not unconditional federal enrollment rights when coverage remains unchanged. |
These screening rules come from the federal SEP regulation and HealthCare.gov’s event-specific guidance. HealthCare.gov
Prior-coverage exceptions deserve a second look. Federal rules include exceptions involving recent residence in a foreign country or U.S. territory, qualifying Indian status, and residence in an area without an available Marketplace plan. Do not reject a marriage or move case solely because the client reports having been uninsured. Check 45 C.F.R. § 155.420(a)(5). ecfr.gov
For the HRA exception, check whether the arrangement was required to provide at least 90 days’ advance notice. Section 155.420(c)(3) supplies a 60-day before-and-after window when that advance-notice requirement did not apply. Obtain the actual notice before calculating the deadline. ecfr.gov
When can SEP coverage start?
| Situation | Usual effective-date rule to check |
|---|---|
| Regular SEP, such as marriage or a qualifying move | First day of the month after plan selection, including selection after the 15th. |
| Plan selected on or before qualifying coverage ends | Generally the first day of the month after the old coverage ends. |
| Plan selected after qualifying coverage has already ended | Generally the first day of the month after plan selection. |
| Birth, adoption, foster placement, or qualifying court order | Event-date coverage is available; ask about a permitted prospective start if requested. |
These are the ordinary starting points in CMS’s SEP job aid. HRA enrollments, corrections, exceptional circumstances, and some Marketplace options require a tailored effective-date check. A 60- or 90-day selection window does not automatically make every uninsured day retroactively covered. cms.gov
4. Additional enrollment opportunities agents should recognize
A Medicaid denial is different from losing Medicaid
A person who never had Medicaid should not report a Medicaid coverage loss. HealthCare.gov provides separate application questions for a recent denial and for termination of existing coverage. HealthCare.gov
A delayed denial can support a different SEP when someone applied during Open Enrollment or another qualifying enrollment opportunity and the Medicaid/CHIP decision arrived after that opportunity ended. Keep the original application date, referral information, denial, and Marketplace determination together. HealthCare.gov
The application’s question about a denial within the past 90 days should not be turned into a promise that every Medicaid denial creates a 90-day SEP. Read the question’s conditions and the eligibility result.
Certain changes in eligibility for savings
An income change warrants an eligibility review; it is not a universal SEP. Specific pathways address changes in premium tax credit or cost-sharing reduction eligibility, certain employer-coverage situations, and some people moving out of the Medicaid coverage gap. The applicable conditions differ. See 45 C.F.R. § 155.420(d)(6). ecfr.gov
Ask what changed in the client’s eligibility, document the genuine financial facts, and let the Marketplace assess the applicable pathway. The former 150% FPL monthly SEP should not be used as a substitute.
Enrollment mistakes and exceptional circumstances
Potential routes include enrollment errors, misleading plan information, serious illness or incapacity that prevented timely enrollment, and qualifying disasters.
For a disaster case, establish the missed enrollment opportunity and how the event prevented enrollment. HealthCare.gov specifies qualifying FEMA county designations and generally allows 60 days after the FEMA-designated incident period ends. A declaration alone does not complete that analysis. HealthCare.gov
Build a short chronology: what the client tried to do, when, what prevented completion, and the requested correction. Save error messages, case numbers, and the resulting determination. Ask the Marketplace to confirm both the enrollment opportunity and any requested earlier effective date.
For a complex federal-platform case, contact the Marketplace Call Center at 1-800-318-2596 with the client. If an SEP request is denied, preserve the notice and follow its appeal instructions and deadline. HealthCare.gov
Other situations to screen
HealthCare.gov also identifies potential pathways for newly eligible immigration status, release from incarceration, and beginning or ending specified AmeriCorps service. Match the actual circumstances to the current eligibility rules. HealthCare.gov
Members of federally recognized tribes and qualifying Alaska Native Claims Settlement Act shareholders have a distinct year-round enrollment opportunity and may change plans as often as monthly. Check the rules for family members on the same application. HealthCare.gov
For domestic abuse or spousal abandonment, seek the appropriate Marketplace assistance using the client’s safe contact information. The client may have a pathway to separate coverage. Avoid making a routine shared-account follow-up before confirming how the client can safely receive communications. HealthCare.gov
5. Five client situations that require careful handling
The following examples are illustrative. Confirm the actual Marketplace decision and carrier requirements for each case.
Example 1: The client needs November coverage and a 2027 plan
An employee’s last day at work is October 15, 2026, but employer coverage continues through October 31. The client calls on October 20.
Start with the October 31 coverage end date. If eligible, selecting a current-year Marketplace plan before that coverage ends can provide a November 1 start, subject to confirmation and completion requirements. A separate 2027 Open Enrollment selection addresses January coverage. HealthCare.gov
Your work plan should show two coverage years:
- 2026: complete the SEP review and November–December enrollment.
- 2027: review the next year’s application, available plans, costs, and January effective date.
Compare the client’s providers, prescriptions, expected care, and total cost for each period. Explain any deductible or accumulator implications of changing plans and crossing into a new plan year, using the actual plan documents.
Schedule the 2027 review before treating the current-year enrollment as complete.
Example 2: Medicaid ended more than 60 days ago
A client contacts you on October 10 after Medicaid ended July 31. More than 60 days have passed, but the client is still within 90 days of losing coverage.
The practical response is to evaluate the Medicaid-loss SEP promptly. Obtain the termination notice, verify the household members affected, and determine the earliest available coverage date. The extended selection window does not automatically fill the months without insurance. HealthCare.gov
Ask whether children or other household members remain eligible for Medicaid/CHIP. A household does not necessarily move into Marketplace coverage as one unit.
Example 3: “I quit, so I assumed I could not qualify”
Leaving employment voluntarily and voluntarily canceling insurance are different facts. The relevant question is whether the person lost eligibility for qualifying employer coverage.
Ask the employer for a coverage-termination record. Do not deny the possibility of an SEP simply because the client resigned. Conversely, a person who keeps access to coverage and merely stops paying or cancels it generally does not create a qualifying coverage-loss event. HealthCare.gov
Also identify the policy type. Expiration of short-term limited-duration insurance does not itself establish loss of qualifying coverage for this SEP. cms.gov
Example 4: COBRA suddenly becomes expensive
A client says, “My COBRA bill doubled.” Determine why before choosing an SEP.
If the employer’s contributions completely ended, or an applicable government subsidy ended, a qualifying event may exist. If the premium simply increased while contributions continued, that is a different situation.
Also check whether the original 60-day window following loss of job-based coverage is still open. HealthCare.gov
Keep the contribution-ending notice, benefit period, and client confirmation. Verify the replacement start date before advising the client about ending existing coverage.
Example 5: An uninsured client is pregnant
Pregnancy alone does not create a HealthCare.gov SEP; birth does. Screen for Medicaid/CHIP and any other qualifying event. HealthCare.gov
Then check the state. New Jersey, for example, expressly recognizes pregnancy as an SEP trigger. A national answer that stops at the federal pregnancy rule can miss a valid state opportunity. When Can I Buy Health Insurance?
For a client expecting a child, create a follow-up plan for reporting the birth, identifying the baby’s coverage, and verifying the effective date. Do not assume the baby has been added to a Marketplace plan because a parent is already enrolled.
6. State Marketplace differences can change the answer
Confirm state rules at intake, particularly for pregnancy, special state enrollment programs, effective-date choices, and deadlines.
For example, Covered California’s 2027 Open Enrollment runs November 1, 2026–January 31, 2027, and existing members can begin renewing or switching their 2027 plans October 1. Those dates differ from the federal platform’s calendar. Covered California
For every state-specific pathway, save the current official guidance or relevant notice with the review. A general national chart should not be the sole basis for selecting an application answer.
7. Check which household members can change plans
An SEP determination does not automatically give everyone on an existing Marketplace application unrestricted access to every plan category.
| Situation | Plan-selection issue to check |
|---|---|
| Existing enrollee uses a common SEP | Choices may be limited to the current metal category. |
| Household adds a spouse or child | The new member can generally join the current plan or enroll separately; existing members do not automatically receive unrestricted shopping rights. |
| Current plan cannot add the new member | Check same-category alternatives and the limited adjacent-category exception. |
| Client newly qualifies for cost-sharing reductions | A move into Silver may be available to use those savings. |
| Silver enrollee loses cost-sharing reductions | Bronze, Silver, or Gold choices may be available. |
| Client becomes newly ineligible for advance premium tax credits | Federal rules allow a change to a plan at any metal level. |
HealthCare.gov explains the common restrictions and exceptions in its plan-changing guidance; the additional APTC-loss exception appears in 45 C.F.R. § 155.420(a)(4)(ii)(C). Check the enrollment platform’s permitted choices before preparing a recommendation. HealthCare.gov
When changing plans, also confirm providers, formulary, referral requirements, and how the insurer treats amounts already paid toward the deductible and out-of-pocket limit. Keep the comparison with the client’s selection decision.
8. Build an SEP file that shows what happened and what was completed
Step 1: Obtain consent and explain the specific SEP request
For federal-platform assistance, obtain and document consumer consent before assisting with enrollment. Before submitting an SEP eligibility request, explain the specific event and SEP and obtain the consumer’s authorization for that request.
These are substantive requirements under 45 C.F.R. § 155.220(j)(2)(iii) and (viii). ecfr.gov
A practical confirmation might be:
“You told me your employer coverage ends October 31. We are asking the Marketplace to determine whether you qualify for the loss-of-coverage Special Enrollment Period. Is that information correct, and do you authorize me to submit that request?”
This example supplements the required consent and application-review process. Document the consumer’s response through an acceptable method.
Step 2: Document the client’s application review before submission
The consumer must review and confirm the accuracy of the eligibility application before submission. Keep the required record, including the relevant application attestations. General permission to help does not establish that the consumer reviewed the completed information. ecfr.gov
As a working practice, review the event, dates, household, coverage, contact information, and income entries together. Record corrections before sending the application.
The consent and application-review documentation must be retained for at least ten years. Keeping event evidence, notices, and follow-up records alongside them is a useful agency file-management practice. cms.gov
Related guide: ACA consumer consent vs. application review.
Step 3: Keep three deadlines separate
- Plan-selection deadline: the applicable SEP window.
- Requested-document deadline: the date in the Marketplace notice. HealthCare.gov generally allows 30 days after plan selection for requested SEP proof.
- First-premium deadline: the insurer’s deadline, when a payment is required.
The document period does not extend the plan-selection window. If the eligibility notice requests no SEP documents, HealthCare.gov says none are required solely for that step. HealthCare.gov
Step 4: Submit useful evidence and track the decision
For a coverage-loss request, the documents need to establish the affected person, prior coverage, and end date. HealthCare.gov accepts several types of records and may allow multiple documents to establish the necessary facts.
If acceptable documents cannot be obtained, use the published explanation process; acceptance is a Marketplace decision. HealthCare.gov
Useful working records include:
| Issue | Examples to locate, subject to the actual request |
|---|---|
| Coverage loss | Employer, insurer, Medicaid/CHIP, or COBRA notice showing the person and termination date. |
| Permanent move | Old/new address and move-date evidence; qualifying prior coverage or exception documentation when applicable. |
| Household change | Marriage, birth, adoption, placement, or court records relevant to the event. |
| Enrollment error | Dated screenshots, notices, call reference numbers, and a concise chronology. |
Treat the list as preparation guidance, not a universal upload requirement. HealthCare.gov’s move-document page describes address and prior-coverage evidence for that situation. HealthCare.gov
Save the upload confirmation, then assign a follow-up owner. A received document and an accepted document are different file statuses. Recheck the eligibility result instead of assuming submission resolved the issue.
Related guide: ACA Marketplace data matching issues. An income or immigration data-matching issue may coexist with an SEP issue; track each notice and deadline separately.
Step 5: Confirm the enrollment is active
Have the client make any required first-premium payment directly to the insurer, then verify enrollment status. HealthCare.gov distinguishes choosing a plan from completing enrollment. HealthCare.gov
Before closing the task, record the carrier, plan, approved effective date, verification status, and payment status. Give the client a written explanation of what is active, what remains pending, and who to contact if an ID card or confirmation does not arrive.
If verification delays affect use of coverage, ask about the approved effective date and any premiums owed for earlier months. Do not promise immediate usable coverage based on a submitted application alone. HealthCare.gov
9. Printable ACA SEP checklist for agents
Before application submission and plan selection
- State and Marketplace identified.
- Coverage year and desired start date identified.
- Each affected household member identified.
- Triggering event and actual coverage dates confirmed.
- Prior-coverage requirement or exception checked.
- Plan-selection deadline identified.
- Permitted household and plan-category changes checked before recommending a plan.
- Consumer consent documented.
- Specific SEP request explained and authorized.
- Application information reviewed and confirmed by the consumer.
After submission
- Plan selected within the applicable window.
- Eligibility notice saved and requested evidence addressed.
- Outstanding SEP verification and data-matching tasks assigned.
- Client received next steps and any required future-year review appointment.
Before marking enrollment complete
- Required SEP verification resolved.
- First premium paid, if required; keep an unpaid enrollment pending.
- Approved effective date and active carrier enrollment confirmed.
- Any remaining data-matching issue continues as a separate tracked task.
Dates and decisions to record
| File item | Client-specific entry |
|---|---|
| Qualifying event and affected person | ______________________________ |
| Qualifying event date | ______________________________ |
| Last day of prior coverage | ______________________________ |
| Notice received date, when relevant | ______________________________ |
| Last date to select a plan | ______________________________ |
| Requested-document deadline | ______________________________ |
| Approved coverage effective date | ______________________________ |
| First-premium deadline, if applicable | ______________________________ |
| Marketplace case number / decision | ______________________________ |
| Follow-up owner and date | ______________________________ |
This checklist is a suggested agency workflow. The governing requirements are identified in the preceding sections and sources.
Keep the evidence available for the next person who needs it
A useful SEP file lets another authorized team member understand the client’s event, the basis of the request, what the client confirmed, and whether coverage became active. Organize the records around those questions.
