SEP Verification Deadlines: What DMI and SVI Are and Why They Matter
Applying for health coverage through a Special Enrollment Period (SEP) under the Affordable Care Act (ACA) requires more than stating that you qualify. In many cases, the Health Insurance Marketplace must verify the information you provide, and this is where two commonly misunderstood terms come into play: DMI and SVI.
Failing to understand what these verification statuses mean, how they work, and the deadlines associated with them can lead to delays, loss of financial assistance, or even cancellation of your enrollment. This guide explains what DMI and SVI are, why they matter, and how to comply with verification requirements correctly.
Why the Marketplace Verifies SEP Information
The Marketplace automatically cross-checks your application details with federal and state databases. When information cannot be verified automatically, your application is flagged for manual review.
Verification ensures that:
A qualifying life event actually occurred
The event date is accurate
You meet SEP eligibility requirements
Your personal and financial data is consistent
This process is where DMI and SVI appear.
What Is DMI in the Marketplace?
DMI stands for Data Matching Issue.
What a DMI Means
A DMI occurs when the information you reported does not match available government records. This does not necessarily mean the information is wrong—it simply means the Marketplace cannot confirm it automatically.
Common DMI Examples
Income that differs from IRS records
Recent job changes
Name or date of birth discrepancies
Social Security number verification issues
Pending immigration status confirmation
What Is SVI in the Marketplace?
SVI stands for Special Verification Issue.
What an SVI Means
An SVI is directly related to verifying the qualifying life event that gives you access to a Special Enrollment Period. The Marketplace requires proof that the event actually occurred.
Common SVI Examples
Loss of prior coverage not confirmed automatically
Recent relocation
Marriage
Birth or adoption
Household composition changes
Key Differences Between DMI and SVI
Although often confused, they serve different purposes:
DMI
Verifies personal or financial data
May affect subsidies
Usually allows longer deadlines
Coverage may continue during review
SVI
Verifies the qualifying life event
May affect SEP eligibility
Often has stricter, shorter deadlines
SEP can be canceled if not verified
Both must be addressed promptly.
Why Verification Deadlines Matter
Each verification type has strict deadlines. Missing them may result in:
Enrollment cancellation
Loss or adjustment of premium tax credits
Repayment obligations at tax time
SEP closure
Typical DMI Deadlines
Most DMI cases allow:
Up to 90 days to submit documents
Coverage may remain active during this period
Subsidies may be adjusted later
Risks of Ignoring a DMI
Failure to resolve a DMI can lead to:
Loss of premium tax credits
Unexpected tax liabilities
Continued coverage without financial assistance
Typical SVI Deadlines
SVI cases usually have:
About 30 days to submit proof
Sometimes even shorter deadlines
Missed deadlines may void your SEP
Risks of Ignoring an SVI
Full enrollment cancellation
Loss of access to coverage outside Open Enrollment
Need to wait for the next enrollment period
Documents Commonly Requested for DMI
Depending on the issue, the Marketplace may request:
Tax returns
Recent pay stubs
Employer verification letters
Immigration documents
Government-issued ID
Documents must be:
Clear and legible
Official and unaltered
Dated
Consistent with your application
Documents Commonly Requested for SVI
To verify a qualifying event, the Marketplace may request:
Proof of loss of coverage letter
COBRA notices
Lease agreements or mortgage statements
Marriage certificates
Birth or adoption records
Medicaid or CHIP eligibility notices
Submitting incorrect documentation may result in rejection.
How to Know If You Have a DMI or SVI
You may be notified through:
Marketplace account messages
Official emails
Requests for supporting documents
Notices stating “verification needed”
These notifications should never be ignored.
How to Upload Documents Correctly
Best practices include:
Use PDF or JPG formats
Avoid blurry photos
Do not alter documents
Upload only what is requested
Double-check names and dates
Always keep submission confirmations.
What Happens During the Review Process
While verification is pending:
Coverage may remain active
Start dates may be delayed
Additional documents may be requested
Final determinations may take several weeks
Consistent follow-up is essential.
Common Mistakes to Avoid
Confusing DMI with SVI
Assuming verification resolves itself
Uploading incorrect documents
Missing submission deadlines
Ignoring Marketplace notices
These mistakes are among the leading causes of coverage loss.

You don’t understand what’s being requested
