How to Find the Best Health Insurance for You in Colorado
The following recommendations will ensure that buying health insurance that is ideal for you is easy.
Decide on your coverage needs before buying
When looking for the best health insurance, weigh the monthly cost against the maximum out-of-pocket limits for plans. If you go to the doctor often, a plan with a higher monthly fee but lower MOOP can save you money. But you may not need as much coverage if you're not high risk. Also, compare health insurance plan types to ensure how flexible a provider will be in covering you.
Compare company offerings and reputations
Before comparing rates, understand what plans the top companies in your area offer and their terms. Also, look into company reputations through forums and industry sources like J.D. Power to ensure a smooth buying and coverage claims process.
Shop around
Comparing multiple plans from many providers ensures you get the best possible deal. We found that rates can start at $316 monthly in Colorado, depending on your profile and chosen plan type. Open Enrollment lasts from November 1 to January 15, but you may also qualify for Special Enrollment if you've lost your job, divorced or had a child.
Take advantage of federal programs and subsidies
Those with low income, have a qualifying disability or illness, or are 65 years old or older can receive subsidies or be eligible for Medicare plans. In some cases, depending on your details, you can have up to 100% of your premiums covered if you're low-income or have significant savings if you're eligible for Medicare. MoneyGeek also provides information for finding the top Colorado Medicare Supplement and best Medicare Advantage plans in Colorado if you want to learn more.

How We Chose the Best Health Insurance in Colorado
To rank health care insurance providers in Colorado, MoneyGeek researched premiums, out-of-pocket costs, claims denial rates and plan types for each available company and compared them across different categories. We then weighted each category to calculate an overall MoneyGeek score and derive rankings.
We weighted most categories as follows:
- Maximum out-of-pocket (MOOP) score (30%): The MOOP is the most you'll pay per year for health care costs outside of your monthly premiums. The provider with the lowest average MOOP scores the highest.
- Claims denial score (30%): How often a provider denies claims. The provider with the lowest claims denial rate scores the highest.
- Rate score (20%): How much the provider's monthly plans cost. The cheapest provider, on average, gets the highest score.
- Plan type score (20%): Providers score better if they have plan types with broader coverage. A provider with many PPO plans will get the highest score.
In some cases, we adjusted the weightings as follows:
- For the categories "Best Cheap Health Insurance in Colorado" and "Best Health Insurance in Colorado for Low Income," we increased the rate score weighting to 50%. We decreased every other category by 10%.
- For the category "Best Health Insurance by Plan Type in Colorado," we decreased the plan type score weighting to 0% to reflect that we are comparing providers' plans like-for-like. We increased MOOP and claims denial score weightings by 10% each.
