Residents of Whatcom County who buy individual health insurance through Washington State's insurance exchange are facing another substantial premium increase next year. The Washington State Office of the Insurance Commissioner announced on September 9, 2026, that it has approved an average rate increase of 22.2% for individual health plans sold on the exchange for 2027, following a 21% increase that took effect in 2026.
What the Rate Increase Means for Whatcom County Residents
The exchange market primarily serves people who do not receive health coverage through an employer. That includes self-employed residents, people who work part-time or for small businesses with fewer than 50 employees, early retirees, and anyone else purchasing individual coverage on the open market. In Whatcom County, three carriers are approved to sell exchange plans in 2027: Coordinated Care Corporation, Kaiser Foundation Health Plan of Washington, and LifeWise Health Plan of Washington.
The approved rate changes vary by carrier. Coordinated Care, which is one of the larger exchange insurers statewide, received a 25.2% increase approval on rates covering 97,979 members across Washington. Kaiser's two Washington-based plans received increases in the 10% to 14.1% range, making them among the more moderate increases in the market. LifeWise was approved for a 22.5% increase. Specific Whatcom County premium amounts will depend on the plan chosen, the age of the enrollee, and household income, which determines eligibility for subsidies.
To put the two-year trajectory in concrete terms: a plan that cost $500 per month in 2025 would have risen to roughly $605 after the 2026 increase. Adding a 22.2% increase on top of that brings the same plan to approximately $739 per month by 2027. For a household buying two individual plans, that represents nearly $18,000 per year in premiums before any deductibles or cost-sharing. The financial pressure on families and individuals in this market is substantial and growing.
Open enrollment for 2027 plans begins November 1. Residents currently enrolled in exchange plans will receive renewal notices showing their new premiums and have the option to shop for alternatives during the enrollment window.
Why Rates Are Rising So Sharply
The Washington State Office of the Insurance Commissioner identified four primary factors driving the 2027 increases. Healthcare organizations have raised charges for services and prescription drugs. Members have increased their utilization of services and shifted toward higher-cost care settings. Departing carriers from the market left behind an enrollee pool with higher average medical needs and therefore higher costs. And the expiration of federal Enhanced Premium Tax Credits has led healthier members to drop coverage, concentrating sicker and more expensive enrollees in the remaining pool.
That last factor is significant. The federal tax credits, which were expanded under pandemic-era legislation, reduced annual premium costs by an average of $1,330 per enrollee when they were in effect. After Congress allowed those credits to expire, enrollment on the Washington exchange fell by 13% in 2026 to approximately 250,000 residents. When healthier, lower-cost people leave the risk pool because coverage becomes unaffordable, the remaining enrollees tend to have greater medical needs, which drives premiums higher for everyone who stays. This dynamic is sometimes called an adverse selection spiral, and it is one of the most challenging structural problems in individual insurance markets.
The departure of carriers from the market compounds the problem. Insurers that exit take their lower-risk enrollees with them, and the remaining carriers absorb a population that skews toward higher utilization. Community Health Plan of Washington, which serves 36,854 members and received a 30.5% rate increase approval for 2027, illustrates how dramatically costs can shift when a carrier's risk pool changes composition.
Insurance Commissioner Patty Kuderer acknowledged the difficulty directly. "This is, unfortunately, a reflection of the increasing cost of care," Kuderer said. "Families shouldn't experience sticker shock every year when shopping for health insurance, but these pressures are likely to continue without changes that slow health care spending, improve affordability and keep more people covered."
What Whatcom County Residents Should Do Before November 1
With open enrollment beginning November 1, residents who currently have exchange coverage or are considering buying it have about six weeks to prepare. The most important step is reviewing the specific plans available in Whatcom County and comparing premiums, deductibles, provider networks, and out-of-pocket maximums. Not all plans increase at the same rate, and switching to a different carrier or tier may result in a lower increase than auto-renewing the current plan.
Washington Healthplanfinder, the state's official exchange website, is the enrollment platform. Certified application counselors and navigators are available across Whatcom County to help residents compare options at no cost. The Washington Healthplanfinder website also has a preview tool that allows shoppers to see available plans and estimated prices before open enrollment officially opens. Using that preview tool before November 1 can help residents avoid scrambling at the last minute and give them time to gather the income documentation they will need to complete an application.
Providence Health Plan, which covered 254 enrollees in Washington in 2026, will not offer individual coverage in 2027, meaning any current Providence exchange enrollees in Washington will need to select a new plan. Asuris Northwest Health sells plans only outside the exchange, and its requested 14.9% increase is pending review by the commissioner's office.
The rate announcement affects people across the political and economic spectrum who rely on the individual market for coverage. Farmers, small business owners, freelancers, and gig workers in Whatcom County are among those most directly affected. For Whatcom County's agricultural community in particular, where many farm operators and their families purchase coverage on the individual market rather than through an employer group plan, back-to-back 20-plus-percent increases represent a serious financial strain.
