6 Mistakes People Make When Choosing a Health Insurance Plan

June 17, 2026

What to Watch for When Choosing Your Health Insurance Plan



Where do you start when choosing a health insurance plan? There are so many options, so many confusing terms and different cost structures... it can seem impossible to know how to pick wisely.


Unfortunately, many people only realize they chose the wrong plan after they start using it. Understanding a few common mistakes can help you avoid unnecessary costs and choose coverage that better fits your needs.



1. Only Looking at the Monthly Premium


One of the most common mistakes people make is choosing a plan based solely on the monthly premium. While a lower premium can make a plan seem more affordable, it often comes with:


  • Higher deductibles
  • Higher out-of-pocket costs
  • Less coverage before the deductible is met


For example, a plan with a $300 monthly premium may look cheaper than a $450 plan. However, if the lower-cost plan has a $7,500 deductible, you may pay significantly more when you actually need care.


When comparing plans, it's important to consider the total potential cost, including deductibles, copays, and the out-of-pocket maximum.



2. Ignoring the Provider Network


Another common mistake is not checking whether your preferred doctors, specialists, or hospitals are in-network. Health insurance plans work with specific providers who agree to negotiated pricing. If you visit an out-of-network provider, you may experience:


  • Much higher medical bills
  • Reduced coverage
  • In some cases, no coverage at all


Before selecting a plan, it's wise to confirm that your current doctors, nearby hospitals, and preferred specialists participate in the network.



3. Not Reviewing Prescription Drug Coverage


Prescription drug coverage can vary significantly between plans.


Each insurance plan has a formulary, which is a list of covered medications. Drugs are typically grouped into tiers, which determine how much you pay.


If your medication falls into a higher tier, or isn't covered at all, you could face much higher out-of-pocket costs.


Before enrolling, check:


  • Whether your medications are covered
  • What tier they fall under
  • What your copay or coinsurance will be


This step can help avoid unexpected prescription expenses throughout the year.



4. Choosing the Wrong Deductible for Your Situation


Some people automatically choose the lowest deductible plan, while others choose the highest deductible plan to save on premiums.


The right choice usually depends on your healthcare needs.


A high deductible plan may work well for people who are generally healthy and want lower monthly premiums.


A low deductible plan may be a better fit for individuals who:


  • Visit doctors regularly
  • Take ongoing medications
  • Have chronic health conditions


The goal is to find the right balance between monthly costs and potential out-of-pocket expenses.



5. Not Understanding the Out-of-Pocket Maximum


Many people overlook one of the most important features of a health insurance plan: the out-of-pocket maximum.


This is the most you will pay for covered healthcare services during the plan year.


Once you reach this amount, your insurance company typically pays 100% of covered services for the rest of the year.


Understanding this number is important because it represents your worst-case financial scenario if you experience a major medical event.


Plans with lower out-of-pocket maximums often provide greater financial protection, even if their premiums are slightly higher.



6. Not Asking Questions or Using Your Insurance Advocate


Many people try to navigate health insurance on their own, but they don't have to.


When you enroll in a health insurance plan, you typically have access to an insurance advocate, usually your agent or broker team, whose job is to help you understand and use your benefits.


We can assist with things like:


  • Explaining how your coverage works
  • Helping resolve claim issues
  • Navigating prior authorizations
  • Answering benefit questions
  • Helping you understand medical bills


Health insurance is complex, and every person's needs and experiences are different. Asking questions can help you avoid confusion, unexpected costs, and unnecessary stress.


If you're ever unsure about how something works, don't hesitate to reach out. Your insurance advocate is here to help you make the most of your coverage.
