If you’re reading this with only a few days left in Covered California Open Enrollment, you’re not alone.
Many people enroll near the deadline. That doesn’t mean they’re careless. It simply means the margin for error is smaller. Certain mistakes, especially when decisions are rushed, can affect your costs, access to care, or tax situation for the entire year ahead.
When those details are missed, the consequences usually don’t show up right away — they show up months later, when changes are harder to fix.
Below are five common last-minute mistakes we see during Open Enrollment, why they happen, and what you can still do now to reduce risk.
(This is the same guidance we walk clients through every Open Enrollment at Rock Meadow Insurance Services—not because people aren’t paying attention, but because the details matter.)
Jump to a Mistake
- Mistake #1: Guessing Your Income Instead of Estimating It Carefully
- Mistake #2: Checking “In Network” Without Understanding How Care Is Delivered
- Mistake #3: Skipping Verification Requests
- Mistake #4: Choosing the Lowest Premium Without Reviewing Tradeoffs
- Mistake #5: Assuming You’re Locked In After You Enroll
Mistake #1: Guessing Your Income Instead of Estimating It Carefully
What the mistake is
Entering a rough income number just to move through the application.
Why it happens
Income questions can feel technical, especially if your income fluctuates, you’re self-employed, or your situation changed during the year. When time is short, it’s tempting to estimate quickly and move on.
Why it matters
Your income estimate determines your monthly financial assistance.
- If it’s too low, you may receive more help than you qualify for and have to reconcile it at tax time.
- If it’s too high, you could miss out on assistance you were actually eligible for.
How to reduce risk now
- Use expected annual income, not just last year’s total
- Include all taxable sources such as wages, self-employment income, and unemployment
- If unsure, estimate thoughtfully and update it later, income changes can be reported during the year
A few extra minutes here can prevent a surprise months down the road.
Mistake #2: Checking “In Network” Without Understanding How Care Is Delivered
What the mistake is
Confirming that a doctor is “in network” without understanding how the plan actually delivers care.
Why it happens
Provider search tools often give a simple yes-or-no answer, which feels reassuring when you’re moving quickly.
Why it matters
In California, how a plan delivers care can matter just as much as whether a doctor technically accepts the insurance. This often shows up in how referrals are handled, which medical groups you’re assigned to, and where you can actually receive care. When expectations don’t line up, people are often surprised later.
How to reduce risk now
- Look beyond the carrier name and review plan details
- Confirm that your preferred doctors and facilities align with the plan
- If continuity of care matters, double-check before enrolling
This is one of the most common “I wish I had known” issues we hear each year.
Mistake #3: Skipping Verification Requests Because “I’ll Handle It Later”
What the mistake is
Submitting the application but overlooking follow-up requests for documentation.
Why it happens
Coverage may appear active, and notices don’t always feel urgent, especially around holidays or busy periods.
Why it matters
Covered California may need additional information to verify eligibility. If requests go unanswered, it can affect financial assistance or coverage status.
How to reduce risk now
- Check your Covered California inbox after enrolling
- Upload requested documents promptly
- Save confirmation of submission for your records
Enrollment isn’t fully settled until verification is cleared.
Mistake #4: Choosing the Lowest Premium Without Reviewing the Tradeoffs
What the mistake is
Selecting the cheapest monthly premium without reviewing deductibles, copays, or cost-sharing.
Why it happens
Premiums are the most visible number and the easiest one to compare when time is tight.
Why it matters
Lower premiums often come with higher costs when care is actually used. Over the course of a year, that tradeoff can add up—sometimes significantly.
How to reduce risk now
- Look at total yearly cost, not just the monthly premium
- Review primary care, specialist, and prescription costs
- Consider how often you realistically use care, not best-case scenarios
Mistake #5: Assuming You’re “Locked In” Once You Click Enroll
What the mistake is
Believing there’s no opportunity to review or adjust anything after enrollment is submitted.
Why it happens
Deadlines create pressure, and everything feels final.
Why it matters
While plan changes are limited after Open Enrollment, certain updates, such as income changes or corrections—are allowed and can make a meaningful difference.
How to reduce risk now
- Enroll first if time is short, then review carefully
- Make corrections promptly if something looks off
- Keep copies of your application and plan summary
A timely review can still prevent long-term issues.
A Steady Reminder as the Deadline Approaches
Last-minute enrollment doesn’t have to mean long-term consequences. Most mistakes happen because people rush through areas that deserve a brief pause, not because they’re careless.
If you slow down just enough to review income, provider access, and plan design, you can meaningfully improve how your coverage works all year.
And if you want support, it doesn’t have to feel like a sales pitch. For many people, working with a local, certified agency like Rock Meadow Insurance Services is simply a way to get a second set of experienced eyes on their choices, at no cost for Covered California enrollments.
Even now, clarity matters.
