South Dakota program

Free health insurance for your child (South Dakota Medicaid)

South Dakota’s free Medicaid plan for children under 19. It can sit behind insurance you already have.

What it is

South Dakota’s free Medicaid plan for children under 19. It can sit behind insurance you already have.

Medicaid can help with treatment costs even when your child already has insurance. South Dakota checks this month’s income and your child’s household. A drop in pay can change the answer.

Eligibility rules
  • Your child must live in South Dakota and be under 19. The income line is the same at every child age.
  • The state uses your child’s tax household and decides which income counts. A yearly amount divided by 12 is only an estimate.
  • Published monthly limits are $3,372 for two people, $4,258 for three, $5,143 for four and $6,027 for five. These include the five-point allowance.
  • Your child needs an eligible citizenship or immigration status, which the state checks separately from income. The social worker can ask for a status-specific review.
Why families with insurance still consider Medicaid
  • Your work plan pays first. Medicaid can help with covered costs left over.
  • There is no premium for child Medicaid, and it can help with dental care, vision care and treatment trips.
What to weigh before changing coverage
  • Ask the hospital to check your cancer team, pharmacy and treatment under both plans. Managing two plans also means keeping both insurance cards and billing details up to date.
  • Medicaid does not cover every service or every clinic. The financial counselor can compare the work-plan premium with the access it preserves.
What you get
  • No premium or copays for your child’s covered hospital care, cancer treatment, medicines and tests.
  • Dental and vision care, plus help with trips to covered appointments.
  • Earlier medical bills can qualify for payment.
What the help includes
  • Home nursing needs a separate medical assessment and approval. Travel help has its own rules.
  • ARSD 67:16:01:07 requires payment in full for covered care under Medicaid’s billing rules. Your care team and billing office can check enrollment, referrals, approvals and coverage on the service date.
  • Your work plan is billed first. For covered care, the clinic cannot bill you the deductible or copay the work plan left, even when Medicaid pays nothing extra. If a bill arrives anyway, ask the financial counselor to check it before paying.
  • Worked example (illustrative figures): the work plan allows $8,000, pays $4,000 and lists $4,000 as your share. Medicaid allows $3,500 and so pays nothing extra. For covered care from an enrolled clinic, you still owe $0, not $4,000.
If you decide to apply
  1. Your hospital social worker can compare Medicaid with your current coverage and help with BEES if it fits.
  2. Have current pay records, birth dates, insurance cards and earlier bills ready. Include months when income changed.
  3. Ask the financial counselor whether the hospital offers temporary Medicaid while you wait.

After you ask
  • The usual decision standard is 45 days, or 90 days when a disability decision is needed.
  • Approved children get 12 months of continuous eligibility, subject to program exceptions.
  • If Medicaid says no, you have 30 days from the date on the letter to ask for a hearing; count from the letter date to be safe. A hearing decision usually comes within 90 days.
  • When an existing service is reduced or stopped, a request before the action takes effect generally keeps it in place during review. Exceptions apply, and Medicaid may seek repayment if its decision is upheld. A new service request is different. Your care team can support urgent handling and DSS can confirm its timing.
Good to know

Work insurance can stay in place and gets billed first. The hospital can check how both plans cover your child’s treatment.

Other details
  • Eligible bills can reach back three months before the application month through 2026. For applications from January 1, 2027, South Dakota says this becomes two months.
  • A participating qualified hospital can start temporary coverage on the day it finds your child eligible. Without a full application, that coverage ends on the last day of the following month. A full application made by then can keep it in place until DSS decides. Your hospital social worker can check whether your hospital participates.

Federal background: Medicaid · Using Medicaid with insurance you already have.

Official sources
Ask your social worker

“Our income looks under the children's Medicaid line. What would adding Medicaid behind the insurance we have actually change for our bills, and if you think it is worth applying, could you help us?”

Why I’m asking: I want to understand whether Medicaid could reduce bills without disrupting our child’s care.

Additional program information and published rules

Who does what

The three parts, side by side. The agency decides; nobody on this page does.

You

File in the portal, report this month's income and any insurance, and name the months that already have bills.

Your social worker

The oncology social worker or hospital financial counsellor helps you file and chases the 45-day decision.

The care team

Nothing for ordinary child Medicaid. Medical records matter only for the Disabled Children's Program route.

Who decides
South Dakota Department of Social Services, Economic Assistance, checks income and runs the cover.
Ask your social worker
“Can you help me file for South Dakota Medicaid today, list the bills from the last three months, and ask whether this hospital can open temporary Medicaid while we wait?”

How to apply

First step: Apply at eaportal.sd.gov this week, or call 877-999-5612.

  1. Apply at eaportal.sd.gov this week, or call 877-999-5612.
  2. List the months that already have bills, so the three-month look-back covers the admission.
  3. Ask the hospital financial counsellor whether they can open temporary Medicaid for your child now.

Official application / program page ↗

Where it starts: Apply in the BEES customer portal at eaportal.sd.gov, or call 877-999-5612. Ask the hospital's financial counsellor the same week whether they can open temporary Medicaid for your child.

What to gather

  • Your child's birth certificate or ID and Social Security number
  • A South Dakota address
  • This month's pay for each parent in the tax household
  • Insurance cards, if any
  • Hospital bills from the three months before you apply

How long: The standard is 45 days, or 90 if a disability decision is needed. Once approved, cover reaches back up to three months before the month you applied.

What a yes looks like

A notice with the dates the cover starts and a card for your child. Cover then runs twelve months.

What a no looks like, and the next move

Read whether the no was about income, a missing document or the wrong category. If it was income and your child has no other insurance, ask about the higher uninsured-child line; if your child needs heavy nursing at home, ask about the Disabled Children's Program by name, and appeal by the date on the notice.

Watch out

  • South Dakota counts the tax household and this month's income, not last year's return or everyone under the roof.
  • Do not cancel a work plan to apply. Medicaid pays after it and both can run at once.
  • The three-month look-back drops to two months for applications made from January 1, 2027.

Dates that change this

2026-09-11: South Dakota prints the children's income table but not the date it took effect or the date the next one lands. If your income is near the line, apply and let the office do the sum. (not yet confirmed against the final rule)

2027-01-01: Cover reaches back up to three months before the month you apply now. South Dakota has published that this becomes two months for children and adults from January 1, 2027.

2026-09-11: South Dakota's plan lets a hospital open temporary Medicaid for a child. Which hospitals do it was not published, so ask your hospital's financial counsellor by name. (not yet confirmed against the final rule)

The eligibility facts, as published

Age
birth through age 18
Age max exclusive
19
Income
MAGI budget group; the state plan sets a 182% of poverty base for every child band (S30) and the MAGI methodology deducts an amount equal to five points of poverty (S10), which is the 187% the printed dollars already carry
Insurance status condition
none: private insurance can stay and South Dakota Medicaid pays after it
Residency
South Dakota
Continuous eligibility
12 months, approved by CMS as SD-23-0023
Retroactive months
3 now; South Dakota says 2 from 2027-01-01
Processing standard
45 days, or 90 days when a disability determination is needed

Decisions this site cannot make: Department of Social Services MAGI decision · Hospital presumptive eligibility for a child

Expect friction on: One statewide Economic Assistance line for a very spread-out state; most of the file moves by phone or through the portal

The trap: Do not drop a work plan to get a higher line. South Dakota Medicaid pays behind private insurance, and a child who keeps the work plan is measured against $5,143 for four while an uninsured child is measured against $5,748 — but dropping cover mid-treatment to chase $605 a month of headroom is not worth the gap it opens.
