TEXAS ACA / OBAMACARE
ACA Special Enrollment Period (SEP)
Open Enrollment is not always your only opportunity to enroll in ACA Marketplace health insurance.
Certain life changes may allow you to enroll outside Open Enrollment.
COMMON QUESTION
I Lost My Job and Health Insurance. Do I Have to Wait Until November?
Not necessarily.
Losing qualifying job-based health coverage can create a Special Enrollment Period that allows you to apply for Marketplace coverage outside the annual Open Enrollment Period.
This can include losing coverage through your own employer or losing coverage under a family member's employer plan.
Timing matters.
For loss of qualifying health coverage, you may generally qualify if you lost coverage within the past 60 days or expect to lose it within the next 60 days.
SPECIAL ENROLLMENT PERIOD
What Is an ACA Special Enrollment Period?
A Special Enrollment Period, commonly called an SEP, is a period outside the annual Open Enrollment Period when you may be able to enroll in or change an ACA Marketplace health plan.
SEP eligibility is generally connected to certain qualifying life events or other Marketplace circumstances.
The enrollment window and coverage effective date can vary depending on the event, so it is important not to assume that every SEP follows exactly the same 60-day rule.
QUALIFYING LIFE EVENTS
Common Situations That May Create an SEP
Loss of Health Coverage
Losing qualifying employer coverage, individual coverage, or certain other health coverage may create an SEP.
Marriage
Getting married may create a Special Enrollment Period for Marketplace coverage.
Birth or Adoption
Having a baby, adopting a child, or placing a child for foster care can create an SEP.
Certain Moves
Certain permanent moves, including moving to a new ZIP code or county, may create an SEP when Marketplace requirements are met.
Divorce or Legal Separation
Divorce or legal separation may create an SEP when it results in losing health insurance. Divorce alone without loss of coverage generally does not.
Loss of Medicaid or CHIP
Losing Medicaid or CHIP may create a Marketplace Special Enrollment Period, with special timing rules that can differ from the usual 60-day window.
ENROLLMENT WINDOW
Is an ACA Special Enrollment Period Always 60 Days?
No.
Many common Special Enrollment Periods involve a 60-day window before or after a qualifying life event, but the exact timing depends on the reason for the SEP.
For example, loss of qualifying health coverage can generally allow enrollment during the 60 days before the loss of coverage or during the 60 days afterward.
Loss of Medicaid or CHIP can have different rules. A person may qualify for a Marketplace SEP for up to 90 days after losing Medicaid or CHIP coverage.
Why timing matters:
Don't wait until the end of an SEP window. If you know your qualifying health coverage is going to end, check your Marketplace options early. For loss of qualifying coverage, you may be able to enroll before your current coverage ends.
TEXAS EXAMPLE
Example: Losing Employer Health Insurance
Suppose someone in Texas loses a job and their employer health insurance will end on September 30.
They do not necessarily need to wait until the annual ACA Open Enrollment Period to look for Marketplace coverage.
Loss of qualifying job-based health coverage may create an SEP. A person who expects to lose qualifying coverage may generally apply for Marketplace coverage during the 60 days before the coverage ends.
Why applying early matters:
Starting the Marketplace process before employer coverage ends may help reduce the risk of an unintended gap in health insurance.
COBRA
Does COBRA Affect Special Enrollment?
Losing job-based coverage may give you choices that include COBRA continuation coverage and Marketplace coverage.
If COBRA coverage reaches its normal expiration or you otherwise involuntarily lose eligibility for it, you may qualify for a Marketplace Special Enrollment Period.
However, voluntarily ending COBRA early or simply stopping premium payments generally does not by itself create a new Marketplace SEP.
Important:
Before electing or canceling COBRA, understand how the decision may affect your Marketplace enrollment options and deadlines.
NEW BABY OR ADOPTION
Birth and Adoption Have Special Coverage Rules
Having a baby, adopting a child, or placing a child for foster care can create a Special Enrollment Period.
In these situations, Marketplace coverage may be able to start on the date of the qualifying event, even when plan enrollment is completed afterward within the permitted enrollment period.
Pregnancy by itself does not create a federal Marketplace Special Enrollment Period, although the birth of the child does.
MOVING
Does Moving Qualify for an SEP?
Certain permanent moves can create a Marketplace Special Enrollment Period.
Examples can include moving to a new home in a different ZIP code or county, moving to the United States from another country or U.S. territory, and certain moves involving students or seasonal workers.
Moving solely for medical treatment or temporarily staying somewhere for vacation does not qualify.
Additional prior-coverage requirements may apply to certain types of moves, so eligibility should be checked through the Marketplace.
MEDICAID / CHIP
Losing Medicaid or CHIP?
Losing Medicaid or Children's Health Insurance Program (CHIP) coverage may create an opportunity to enroll through the Marketplace.
You may be able to apply before Medicaid or CHIP ends, and HealthCare.gov currently provides an SEP of up to 90 days after loss of Medicaid or CHIP coverage in applicable situations.
Because these timing rules differ from many other Special Enrollment Periods, don't automatically assume you only have 60 days.
DOCUMENTATION
You May Need to Prove the Qualifying Event
The Marketplace may ask you to provide documents confirming your Special Enrollment Period.
Depending on the event, documentation might involve proof that prior health coverage ended or documents related to another qualifying life event.
Your Marketplace Eligibility Notice will tell you whether documents are required and provide the applicable deadline.
If the Marketplace asks you to confirm your Special Enrollment Period, submit the requested documents as soon as possible. Your Marketplace Eligibility Notice will explain what information is needed and the deadline.
Selecting a plan does not necessarily mean the SEP verification process is finished.
If SEP verification is required, the Marketplace must confirm your eligibility before you can use the coverage. You must also pay the first premium directly to the insurance company before coverage can start.
If HealthCare.gov requires documents to confirm your Special Enrollment Period after you select a plan, you generally have 30 days after plan selection to submit the requested documents. Follow the deadline shown in your Marketplace Eligibility Notice.
IMPORTANT
A Life Change Does Not Automatically Guarantee an SEP
Special Enrollment Period rules depend on the specific event, timing, previous coverage, and other Marketplace requirements.
The Marketplace application and eligibility results ultimately determine whether you qualify for an SEP.
If you think you may qualify, it is generally better to check promptly rather than waiting until the enrollment window may have passed.
NO QUALIFYING EVENT?
What If I Don't Qualify for a Special Enrollment Period?
If you don't qualify for an SEP, you may need to wait until the next annual Marketplace Open Enrollment Period to enroll in an ACA Marketplace plan.
