South Dakota Health Insurance: Marketplace, Private Plans & 2027 Rates

Shopping for health insurance in South Dakota? All three Marketplace insurance companies are continuing for 2027, and the state's approved rate increases are more moderate than the increases being seen in many other markets.

That doesn't mean you should automatically renew. Avera, Sanford Health Plan, and Wellmark have different rate changes, provider networks, service areas, deductibles, and plan designs.

We help self-employed workers, farmers, ranchers, individuals, families, early retirees, and small business owners compare Marketplace coverage with other available health insurance options throughout South Dakota.

South Dakota Uses HealthCare.gov

South Dakota does not operate its own state health insurance Marketplace.

Individuals and families who want ACA Marketplace coverage use the federal Marketplace at HealthCare.gov.

Marketplace Qualified Health Plans are ACA-compliant major medical insurance and include important protections, including:

  • Coverage for pre-existing conditions
  • ACA-required essential health benefits
  • Preventive care
  • Prescription drug coverage
  • Hospital and emergency coverage
  • Annual limits on covered in-network out-of-pocket costs
  • No medical underwriting for eligibility
HealthCare.gov is also where eligible South Dakota residents receive federal Premium Tax Credits. Marketplace financial assistance generally cannot be applied to coverage purchased outside the Marketplace.

South Dakota Marketplace Insurance Companies for 2027

South Dakota continues to have three Marketplace insurance companies for 2027:

Avera Health Plans

Avera continues offering individual Marketplace coverage for 2027.

Avera has a large health-system presence in the eastern part of South Dakota, making network details particularly important when comparing plans.

Sanford Health Plan

Sanford Health Plan is also continuing its South Dakota individual Marketplace coverage for 2027.

Its plans may be particularly relevant for people who use Sanford physicians, clinics, and hospitals.

Wellmark Blue Cross Blue Shield

Wellmark Blue Cross and Blue Shield of South Dakota remains a Marketplace insurer for 2027.

Wellmark's individual Marketplace plans are available only in selected South Dakota counties, so check availability for your ZIP code.

Why Compare If All Three Are Staying?

Staying with the same insurance company doesn't guarantee the same premium, deductible, network, formulary, or cost-sharing structure in 2027.

Approved South Dakota Health Insurance Rates for 2027

South Dakota's 2027 individual-market rate changes have now been approved.

The three Marketplace insurers received the following average rate changes:

Insurance Company Approved Average 2027 Change
Avera Health Plans +11.3%
Sanford Health Plan +10.9%
Wellmark Blue Cross Blue Shield of South Dakota +6.7%

Across the individual market, the approved weighted average increase is roughly 10% before Marketplace Premium Tax Credits are applied.

These are insurer-wide averages, not your personal increase. Your 2027 premium depends on your age, rating area, specific plan, tobacco status where applicable, household information, and any financial assistance for which you qualify.

Why You Should Still Compare Plans for 2027

South Dakota's carrier lineup is stable, but that doesn't mean your existing plan is automatically your strongest option for the new year.

Review:

  • Your actual 2027 monthly premium
  • Your Marketplace Premium Tax Credit
  • Your deductible
  • Your annual out-of-pocket maximum
  • Primary care and specialist costs
  • Hospital and outpatient cost sharing
  • Your prescription formulary
  • Your provider network
A smaller premium increase doesn't automatically make a plan the better fit. A plan with a slightly higher premium could still work better if it includes the doctors, hospitals, prescriptions, and cost-sharing structure you need.

Marketplace Financial Help in South Dakota for 2027

Federal Premium Tax Credits remain available for eligible South Dakota residents who purchase qualifying coverage through HealthCare.gov.

The temporary enhanced Premium Tax Credit rules that applied through 2025 have ended.

Under the general federal rules now in effect, Premium Tax Credit eligibility generally requires household income between 100% and 400% of the federal poverty level, along with the other eligibility requirements.

Based on the 2026 federal poverty guidelines used for 2027 Marketplace coverage, 400% of the poverty guideline is approximately:

One-Person Household

Approximately $63,840 per year.

Family of Four

Approximately $132,000 per year.

Income alone does not determine whether you receive a Premium Tax Credit. Employer coverage, Medicaid or Medicare eligibility, tax filing status, household composition, age, location, and other federal rules can also matter.

Self-Employed Health Insurance in South Dakota

We work with South Dakota farmers, ranchers, agricultural contractors, truck drivers, owner-operators, tradespeople, construction workers, real estate professionals, consultants, freelancers, and other people who buy health insurance without a traditional employer plan.

Self-employed households often have another challenge: estimating annual income for Marketplace financial assistance.

Estimate Net Business Income

Marketplace applications generally use expected net self-employment income after eligible business expenses rather than simply gross business revenue.

Income May Change Significantly

Farm income, livestock sales, commodity prices, contract work, commissions, seasonal employment, and business expenses can all make annual income difficult to predict.

Update Meaningful Changes

If projected household income changes significantly, update your Marketplace application rather than waiting until the next Open Enrollment.

Tax Planning Can Matter

Certain eligible retirement, HSA, and other tax adjustments may affect Adjusted Gross Income and therefore Marketplace MAGI.

Talk with your tax professional about which deductions apply to your situation.

Advance Premium Tax Credits are reconciled when you file your federal tax return. If your actual annual household income differs from the estimate used during enrollment, your final Premium Tax Credit can also change.

Health Insurance for South Dakota Farmers and Ranchers

Agriculture creates some unique health insurance planning challenges.

Farm and ranch income can move significantly from year to year because of crop yields, livestock sales, commodity prices, weather, equipment purchases, operating expenses, and other business factors.

When comparing coverage, consider:

  • Expected household income for the full year
  • Access to hospitals in your part of South Dakota
  • Emergency and accident coverage
  • Specialists who may be located farther away
  • Whether you regularly cross state lines for care
  • Your prescriptions
  • How much deductible exposure you can comfortably absorb
For rural households, network access can matter as much as premium. Check where the nearest in-network hospital, urgent care facility, and specialists are located before choosing coverage.

Seeing Doctors Outside South Dakota? Check the Network Carefully

Provider networks deserve extra attention in South Dakota because many residents live near state borders or travel considerable distances for specialty care.

This can be especially important if you:

  • Live near Sioux Falls and receive care in Minnesota or Iowa
  • Live in western South Dakota and use providers in Wyoming or Nebraska
  • Travel frequently for trucking, construction, or agricultural work
  • Use a specialist outside your local health system
  • Spend part of the year in another state
Don't assume a plan covers non-emergency care across state lines just because the insurance company is well known. Check the exact network attached to the specific plan.

Some non-Marketplace plans may use PPO networks that offer broader provider access, but network size, out-of-network benefits, underwriting, exclusions, and other coverage rules vary by plan.

Marketplace Plans vs. Other Private Health Coverage

South Dakota residents may also encounter individual health products sold outside HealthCare.gov.

These products do not necessarily provide the same benefits or protections as ACA Marketplace coverage.

HealthCare.gov Marketplace Plans

  • ACA-compliant major medical coverage
  • Coverage for pre-existing conditions
  • ACA-required essential health benefits
  • Defined annual out-of-pocket limits
  • No medical underwriting for eligibility
  • Premium Tax Credits for eligible households

Other Private Coverage

  • May be available outside HealthCare.gov
  • Some products may use medical underwriting
  • Pre-existing-condition provisions can differ
  • Benefits and exclusions can differ
  • Provider networks may be structured differently
  • Marketplace Premium Tax Credits generally cannot be used
Compare more than the monthly premium. Review benefits, exclusions, provider networks, prescription coverage, deductibles, out-of-pocket exposure, medical underwriting, and pre-existing-condition rules.

South Dakota Medicaid Expansion

South Dakota implemented Medicaid expansion on July 1, 2023.

The Medicaid Expansion Adult Group covers qualifying adults ages 19 through 64 who meet the applicable income and other eligibility requirements.

Expansion eligibility generally reaches household income up to approximately 138% of the federal poverty level after the applicable Medicaid income rules are considered.

South Dakota Medicaid accepts applications year-round. You don't need to wait for Marketplace Open Enrollment if you believe you may qualify.

South Dakota Medicaid Rules Change January 1, 2027

South Dakota Medicaid Expansion members face several important changes beginning January 1, 2027.

One of the biggest is a new community-engagement requirement for certain adults ages 19 through 64.

Unless an exclusion applies, affected adults generally need to complete at least 80 hours each month of one or more qualifying activities.

Qualifying activities include:

  • Paid work
  • Job training
  • Community or volunteer service
  • Attending school at least half-time
  • A combination of qualifying activities
Not every Medicaid Expansion member has to meet the requirement. South Dakota has multiple exclusions, and DSS will use available information to determine whether someone is exempt or has already met the requirement.

Who May Be Excluded From the South Dakota Medicaid Work Requirement?

South Dakota currently lists several groups that do not have to meet the new community-engagement requirement.

Examples include qualifying people who:

  • Are American Indian or Alaska Native, including people eligible for Indian Health Service
  • Are caregivers for a child age 13 or younger or a person with a disability
  • Are pregnant or eligible for postpartum Medicaid
  • Are medically frail or have a disability, serious medical condition, or other qualifying medical need
  • Are veterans with a total disability rating
  • Are receiving qualifying treatment or rehabilitation for substance-use conditions
  • Are already subject to certain SNAP or TANF work requirements
  • Meet certain foster-care or incarceration-related exclusions
If you have Medicaid, don't assume the rule applies to you. Review notices from South Dakota DSS and respond if additional information is requested.

Medicaid Expansion Renewals Move to Every Six Months

Another major 2027 change involves how frequently Medicaid Expansion eligibility is reviewed.

Beginning January 1, 2027:

  • Medicaid Expansion enrollees generally move from annual renewals to renewals every six months.
  • Adults and children in most other Medicaid coverage groups continue with 12-month renewal periods.
  • American Indian and Alaska Native Medicaid Expansion members are exempt from the six-month renewal requirement.
Keep your address, phone number, and other contact information current with South Dakota DSS. More frequent reviews mean it becomes even more important to open Medicaid notices and respond to requests on time.

South Dakota Medicaid Retroactive Coverage Also Changes in 2027

South Dakota is also changing how far Medicaid coverage can be backdated for eligible applicants.

Beginning January 1, 2027:

  • Retroactive coverage is generally limited to one month for Medicaid Expansion adults.
  • Retroactive coverage is generally limited to two months for applicants in other Medicaid and CHIP groups.
If you believe you're eligible for Medicaid, applying promptly becomes more important under the new retroactive-coverage rules.

Special Health Coverage Rules for Tribal Members

South Dakota has a significant American Indian population, making federal Marketplace and Medicaid protections for Tribal members especially important.

Members of federally recognized Tribes can generally enroll in a Marketplace plan throughout the year.

Once enrolled, eligible Tribal members can generally change Marketplace plans as often as once per month.

Zero Cost-Sharing Plans

Eligible members of federally recognized Tribes with income between 100% and 300% of the federal poverty level may qualify for zero-cost-sharing Marketplace plans.

Limited Cost-Sharing Plans

Tribal members above that income range may still qualify for special limited cost-sharing protections when receiving eligible services through Indian health care providers.

IHS and Marketplace Coverage Can Work Together

Enrolling in Marketplace coverage does not prevent eligible Tribal members from continuing to receive services from Indian Health Service, Tribal health programs, or urban Indian programs.

2027 Medicaid Exemption

American Indian, Alaska Native, and qualifying IHS-eligible Medicaid Expansion members are excluded from South Dakota's new community-engagement requirement.

South Dakota Open Enrollment for 2027

South Dakota follows the federal HealthCare.gov Open Enrollment schedule.

Open Enrollment for 2027 coverage runs from November 1, 2026 through January 15, 2027.

  • November 1, 2026: Open Enrollment begins.
  • December 15, 2026: Select a plan by this date for coverage beginning January 1, 2027.
  • January 15, 2027: Open Enrollment ends. Coverage selected after December 15 generally begins February 1.
Don't automatically accept your renewal. Even with the same three insurers returning, premiums, provider networks, prescriptions, and plan benefits can change.

What If You Lose South Dakota Medicaid?

Losing Medicaid can create a Special Enrollment Period for Marketplace coverage.

This may become especially relevant in 2027 as community-engagement rules and more frequent Medicaid Expansion renewals take effect.

Depending on your circumstances, alternatives may include:

  • A HealthCare.gov Marketplace plan
  • An employer-sponsored health plan
  • A spouse's employer plan
  • Other available individual coverage
If South Dakota Medicaid tells you your coverage is ending, review replacement coverage promptly. Special Enrollment Periods have deadlines.

Leaving a Job or Losing Employer Health Insurance?

Losing qualifying job-based coverage can create a Special Enrollment Period through HealthCare.gov.

Depending on your circumstances, compare:

  • COBRA continuation coverage
  • A spouse's employer-sponsored plan
  • A Marketplace plan through HealthCare.gov
  • South Dakota Medicaid if eligible
  • Other available individual coverage

COBRA can allow you to temporarily keep the same employer coverage, but your premium may increase substantially if the employer is no longer paying part of the cost.

South Dakota Health Insurance for Early Retirees

Retiring before age 65 can create a coverage gap between an employer plan and Medicare eligibility.

Depending on your circumstances, you may compare:

  • HealthCare.gov Marketplace coverage
  • COBRA
  • A spouse's employer-sponsored plan
  • Other available private coverage

Marketplace financial assistance can make income planning especially important because pensions, investment income, taxable retirement withdrawals, farm income, and other income can affect household MAGI.

Retiring does not automatically make you ineligible for Marketplace financial assistance. Eligibility depends on household income and the other applicable Marketplace requirements.

Small Business Health Insurance in South Dakota

South Dakota employers have several ways to approach employee health benefits.

Depending on the company, options may include:

Traditional Group Coverage

Employer-sponsored health insurance where eligible employees participate in the company's group plan.

Level-Funded Coverage

Certain employers may qualify for level-funded arrangements that combine employer funding with stop-loss protection.

Eligibility, underwriting, and refund provisions vary by carrier.

ICHRA

An Individual Coverage HRA can allow an employer to reimburse eligible employees for qualifying individual health insurance under applicable rules.

QSEHRA

Certain qualifying small employers that do not offer group health coverage may reimburse employees for qualifying individual premiums and medical expenses.

Rural employers should pay particular attention to provider access. Employee ZIP codes and where workers actually receive medical care can affect which benefit structure works well.
