Avoid These 5 Common Medicare Enrollment Mistakes During Open Enrollment

How to Avoid Your Covered California Coverage Being Cancelled

After Open Enrollment ends, many people assume their Covered California plan is set for the year. But, early in the year is when most coverage issues occur, often due to missed payments or unanswered requests for information.

The good news is that most cancelation are preventable. Here’s what to watch for and how to keep your coverage active.

The Most Common Reason: Missed Premium Payments

Your monthly premium must be paid directly to your insurance carrier, not to Covered California.

If a payment is missed:

Your carrier may send a late notice
A grace period may begin
Covered could be terminated if payment isn’t made on time

For households receiving premium tax credits, federal rules generally allow a three month grace period before coverage is cancelled, but claims may be delayed or denied during that time (CMS, 2026).

If you’re unsure whether a payment went through, it’s important to confirm right away.

Don’t Ignore Requests for Verification

Covered California may periodically request documentation to verify:

Income
Household Size
Immigration or residency status
Eligibility for financial assistance

These requests often come by mail or through your online account. If the requested documents aren’t submitted by the deadline, your financial assistance, or even your coverage, could be reduced or terminated (Covered California, 2026).

Early in the year is a common time for these eligibility checks.

Report Income or Household Changes Promptly

Your subsidy is based on your estimated annual household income. If your situation changes and isn’t reported, Covered California may later request documentation or adjust your eligibility.

Changes to report include:

Starting a new job or receiving a raise
Reduced hours or job loss
Marriage, divorce, or a new dependent
A household member gaining other coverage

Keeping your information up to date helps prevent eligibility issues later in the year (CMS, 2026).

Understand the Grace Period

If your premium payment is late and you receive financial assistance, the three month grace period usually works like this:

Month 1: Coverage continues normally
Month 2-3 Claims may be held or delayed
End of Month 3: Coverage may be cancelled if the balance isn’t paid

If coverage is terminated for non-payment, you may not be able to re-enroll until the next Open Enrollment unless you qualify for a Special Enrollment Period (Covered California, 2026).

If you receive a letter or email about:

Past-due premiums
