Best Health Insurance in Delaware

With Aetna gone and only three carriers left on Delaware’s marketplace, picking the right one matters more than it used to — and the differences between Highmark, AmeriHealth, and Ambetter go well beyond the monthly premium. One has the widest network in the state, another averages around $730 per month across all metal tiers, and the third bundles telehealth into every plan. This guide compares all three head-to-head so you can figure out which is the best health insurance in Delaware for how you actually use healthcare.

Highmark BCBS leads on network size and plan variety with 15 options and nationwide BlueCard access, AmeriHealth Caritas leads on price at $730 per month average for a 40-year-old, and Ambetter leads on telehealth inclusion across all 17 of its plans. The table below compares key metrics across all three Delaware marketplace carriers based on 2026 approved rate filings and publicly available plan data from CMS.

All premiums reflect a 40-year-old enrollee before subsidies. Actual costs vary by age, county, and subsidy eligibility. Subsidy-eligible enrollees should compare net premiums (after tax credits) rather than sticker prices, since subsidies can significantly narrow or eliminate the premium gap between carriers. For a breakdown of how subsidies and cost-saving strategies work, see the guide to affordable health insurance in Delaware.

Best Health Insurance in Delaware by Situation

Highmark BCBS is the strongest choice for families, chronic conditions, and out-of-state coverage due to its broad PPO network. AmeriHealth Caritas wins for budget-focused enrollees and those pairing Silver plans with cost-sharing reductions. Ambetter suits young adults who prefer telehealth and managed care at mid-range premiums. Enrollees unfamiliar with how the Delaware marketplace works should start there before comparing carriers.

Best for Families

Highmark BCBS — Silver or Gold PPO

Families benefit from Highmark’s broad pediatric specialist network and the ability to see out-of-network providers without a referral. Gold plans keep copays and deductibles lower, which matters more when multiple family members use care regularly.

Best for Low Premiums

AmeriHealth Caritas — Bronze PPO

AmeriHealth offers the cheapest Bronze plan in Delaware at $542 per month before subsidies. Enrollees eligible for premium tax credits can often reduce that to $0 per month, making this the strongest option for healthy individuals who want minimal monthly cost.

Best for Chronic Conditions

Highmark BCBS — Gold or Platinum PPO

Enrollees managing ongoing conditions like diabetes, heart disease, or autoimmune disorders need reliable specialist access and predictable costs. Highmark’s higher-tier plans pair the state’s largest network with lower deductibles (the amount paid before insurance covers costs) and copays.

Best for Young Adults

Ambetter — Silver HMO

Ambetter’s Silver plans offer competitive premiums for adults under 30, and the included telehealth access fits the convenience preferences of younger enrollees who prefer virtual visits for routine care.

Best for Subsidy-Eligible Enrollees

AmeriHealth Caritas — Silver PPO with CSR

Enrollees earning between 100% and 250% of the federal poverty level unlock cost-sharing reductions on Silver plans. AmeriHealth’s Silver options become especially competitive after CSR adjustments, with reduced deductibles and copays that can make a Silver plan perform like Gold.

Best for Travel or Out-of-State Care

Highmark BCBS — Any PPO Tier

Highmark’s BlueCard program provides in-network access to providers across all 50 states. Enrollees who travel frequently, split time between states, or live near Delaware’s borders benefit from coverage that works beyond state lines — something neither AmeriHealth nor Ambetter offers at the same level.

How to Choose the Best Health Insurance Plan in Delaware

Network access, premium-to-deductible ratio, prescription formulary, and total out-of-pocket exposure are the four factors that matter most when identifying the best health insurance in Delaware for 2026. The decision framework below applies each factor to real carrier data so enrollees can weight the tradeoffs based on how they actually use healthcare.

1. Check Provider Networks

Before comparing premiums, confirm that current doctors and preferred hospitals are in-network for the plans under consideration. Out-of-network care can cost two to five times more than in-network care, easily erasing any premium savings from choosing a cheaper plan with a narrower network.

2. Estimate Total Annual Cost

Monthly premium is only one piece of the equation. Add the deductible, expected copays, and coinsurance (the percentage share of costs after the deductible) based on anticipated usage. A lower-premium Bronze plan may cost more over a full year than a higher-premium Gold plan if several specialist visits or prescriptions are needed.

3. Evaluate Subsidy Impact

Subsidies apply only to marketplace plans purchased through HealthCare.gov. Delaware residents earning up to 400% FPL can receive premium tax credits that change which plan tier offers the best net value. The KFF subsidy calculator provides quick estimates by income and household size.

4. Review Prescription Coverage

Each carrier maintains a separate formulary (list of covered medications) with different tier placements and copay structures. Enrollees taking specialty or brand-name drugs should verify their prescriptions are covered — and at what cost tier — before selecting a plan. A single medication placed on a higher formulary tier can add thousands in annual out-of-pocket costs.

Example: A 35-year-old in Newark, Delaware earning $42,000 per year (approximately 270% FPL) would qualify for a premium tax credit of roughly $420 per month. Applying that credit to a Highmark Gold PPO priced at $870 per month brings the net premium to approximately $450 per month — only $80 more than the subsidized AmeriHealth Bronze, but with significantly lower deductibles and copays for regular care.

Frequently Asked Questions

Highmark BCBS ranks first overall for the best health insurance in Delaware for 2026, AmeriHealth Caritas has the lowest average premiums at roughly $730 per month, and premium tax credits can reduce any carrier’s cost to $0 for eligible enrollees. The six questions below cover the topics that come up most often during open enrollment and qualifying life events.

What is the best health insurance company in Delaware?

Highmark Blue Cross Blue Shield of Delaware ranks first overall for 2026 based on the widest provider network, the most plan options across all metal tiers, and nationwide BlueCard portability. AmeriHealth Caritas is the best value option with the lowest average premiums, while Ambetter suits enrollees who prefer managed care with built-in telehealth.

Which Delaware carrier has the cheapest plans?

AmeriHealth Caritas offers the lowest average premiums in Delaware at approximately $730 per month for a 40-year-old across all metal tiers. The cheapest individual Bronze plan through AmeriHealth starts at roughly $542 per month before subsidies. With premium tax credits, eligible enrollees can reduce that cost to $0 per month.

Is Highmark BCBS worth the higher premium in Delaware?

For enrollees who need broad specialist access, out-of-state coverage, or PPO flexibility, the premium difference is often justified. Highmark’s network covers significantly more providers than AmeriHealth or Ambetter, and BlueCard access extends coverage nationwide. Enrollees who rarely see specialists and stay within Delaware may find better value with a lower-premium carrier.

How do subsidies affect which Delaware plan is best?

Subsidies are calculated against the benchmark Silver plan, so they can make higher-tier plans much more accessible. A resident earning 250% FPL might pay only $150 per month for a Gold plan after credits — making Gold a better deal than an unsubsidized Bronze plan for anyone with regular healthcare needs.

Why did Aetna leave Delaware’s health insurance market?

Aetna CVS Health exited the Delaware individual market effective January 1, 2026, as part of a broader national withdrawal from ACA marketplace plans. The departure reduced Delaware’s carrier count from four to three and contributed to the 27.7% weighted average premium increase for the current plan year by reducing competition.

Can I switch health insurance carriers in Delaware outside of open enrollment?

Only through a Special Enrollment Period triggered by a qualifying life event such as losing other coverage, getting married, having a child, or moving to a new area. Outside of these events, the next opportunity to switch carriers is during Open Enrollment, which typically runs November 1 through January 15 each year.
