Colorado health insurance

COVID-19 special enrollment period continues until April 30; Progress continues on public option that's expected to be available by 2022

Health insurance in Colorado

COVID-19 special enrollment period continues until April 30, 2020

As a result of the COVID-19 pandemic, Colorado’s exchange is allowing uninsured residents to sign up for health coverage. The enrollment window runs until April 30. Enrollments completed by April 3 will have coverage effective April 1. Enrollments completed between April 4 and April 30 will have coverage effective May 1. The special enrollment period is only available to people who don’t have minimum essential coverage, so it’s not an opportunity to switch plans. But health care sharing ministry plans and fixed indemnity plans are not considered minimum essential coverage, so people relying on those types of coverage do have an opportunity to enroll during Colorado’s COVID-19 special enrollment period.

Colorado has long been a leader in health reform

State legislative efforts to preserve or strengthen provisions of the Affordable Care Act

Colorado is one of the states fighting hardest to preserve the Affordable Care Act’s provisions. See what the state is doing.

Colorado has long been a leader in terms of health care reform. Before the ACA implemented reform on a federal level, Colorado had already made maternity coverage mandatory in the individual market, and had banned gender-based premiums.

Colorado became the second state in the nation to actively pursue single-payer health care, with Amendment 69 appearing on the 2016 ballot. However, voters rejected the push for single-payer by a wide margin (Vermont was the first state to implement a plan to achieve single-payer, but they abandoned that path in December 2014).

Colorado implemented a reinsurance program as of 2020, joining a growing number of states that are using 1332 waivers to obtain federal pass-through funding for reinsurance to stabilize the individual market. Individual health insurance premiums in Colorado dropped by an average of 20 percent in 2020, thanks to the reinsurance program (although after-subsidy premiums increased for many people who receive premium subsidies).

Colorado is working on a public option program that the state hopes to debut in the fall of 2021, for coverage effective in 2022.

Colorado’s uninsured rate dropped by nearly half from 14.1 percent in 2013, to 7.5 percent in 2018. The Colorado Health Access Survey found an even lower uninsured rate — just 6.5 percent — which has stayed steady from 2017 through 2019.

The Colorado health marketplace

Colorado utilizes a state-run health insurance exchange. While there are eight insurers participating, which is relatively robust compared with much of the country, coverage tends to be localized and plan availability is concentrated in urban areas. In 22 of the state’s 64 counties, those who shop the state’s exchange have a single carrier option (Anthem Blue Cross/Blue Shield) in 2020.

Average premiums in Colorado’s individual market dropped by 20 percent for 2020, but that was before any subsidies were applied. After subsidies, many enrollees saw higher premiums in 2020, due to lower benchmark plan premiums and the resulting decrease in premium subsidy amounts.

Colorado implemented rules to permanently extend open enrollment to 2.5 months, so it runs from November 1 to January 15 each year.

Nearly 167,000 people people enrolled in private plans through Colorado’s exchange during open enrollment for 2020 coverage. That was down from just over 170,000 enrollees in 2019.

Grandmothered plans terminated

Colorado required all grandmothered (transitional) plans to terminate by the end of 2015. There are still grandfathered plans in the state, but all other individual and small-group plans are now ACA-compliant.

Colorado and Medicaid expansion

Colorado is among the 36 states and the District of Columbia that have expanded Medicaid under the ACA. The expansion extends Medicaid eligibility to most nonelderly adults at or below 138 percent of the federal poverty level.

As of late 2019, total Medicaid/CHIP enrollment in Colorado stood at just under 1.26 million people, which was 61 percent higher than it had been in 2013.

Short-term health insurance in Colorado

As a result of strong new state regulations that took effect in 2019, there are no longer any short-term health plans available in Colorado.

Colorado legislators’ positions on the Affordable Care Act

In 2009, Colorado Sens. Mark Udall and Michael Bennet – both Democrats – voted yes on the Affordable Care Act. Colorado’s five Democratic House members also voted yes, while the other two representatives, both Republicans, voted no.

The current Colorado congressional delegation includes Senators Michael Bennett (Democrat) and Cory Gardner (Republican). Bennett supports the ACA, while Gardner opposes it. As of 2020, Colorado has seven representatives in the U.S. House: four Democrats, and three Republicans. Support for the ACA is split along party lines in the state’s House delegation.

At the state level, Colorado was one of the only states that moved in a bipartisan manner to establish a state-run health insurance marketplace. Former Gov. John Hickenlooper, a Democrat, signed legislation authorizing the marketplace in 2011. The state marketplace is called Connect for Health Colorado. The state also adopted Medicaid expansion under the Affordable Care Act.

Colorado’s high-risk pool

Before the ACA reformed the individual health insurance market, coverage was underwritten in nearly every state, including Colorado. People with pre-existing conditions were often unable to purchase coverage in the private market, or were only eligible for policies that excluded their pre-existing conditions or charged them premiums that were significantly higher than the base rate.

CoverColorado was created in 1991 to provide an alternative for people who were not able to get comprehensive coverage in the private market because of their medical history.

One of the primary reforms ushered in by the ACA was guaranteed issue coverage in the individual market. An applicant’s medical history is no longer a factor in eligibility, which means that high-risk pools are no longer necessary the way they once were. CoverColorado stopped enrolling new applicants at the end of 2013, and the program ceased altogether in March 2014.

Medicare coverage in Colorado

By February 2020, there were 926,149 Colorado residents covered by Medicare. About 56 percent of them were enrolled in Original Medicare, with the other 44 percent enrolled in Medicare Advantage plans instead.
