Wyoming program

Government health insurance for your child

Wyoming's free Medicaid plan for children under 19. It can sit behind insurance you already have.

What it is

Wyoming's free Medicaid plan for children under 19. It can sit behind insurance you already have.

Wyoming Medicaid pays for a child's covered care without a premium or child copays. A drop in pay can bring a family under the income limit. Wyoming decides who belongs in your child's household and which income counts.

Eligibility rules
  • Your child must live in Wyoming and be under 19. Household rules follow tax relationships, rather than everyone at one address.
  • The test uses current monthly income. A yearly amount divided by 12 is only an estimate.
  • From April 1, 2026, the published monthly limits for four people are $4,235 at ages 0–5 and $3,658 at ages 6–18. For three people they are $3,507 and $3,028.
  • The line already includes the state's allowance for a family just over it.
Why families with insurance consider this
  • Work insurance is billed first. For covered, properly approved care at an enrolled clinic, Medicaid generally protects you from the work plan’s deductible, coinsurance and copay, even when Medicaid adds no payment.
  • There is no premium for this child coverage.
  • Wyoming can separately review an active work premium through WHIPP.
What to compare
  • The financial counselor can check whether the cancer team and pharmacy accept both plans.
  • Two plans mean two sets of billing and treatment-approval rules.
What you get
  • No premium or child copays for covered hospital care, chemotherapy and medicines.
  • Help getting to covered appointments.
  • Eligible bills from before the application month can also be covered.
Coverage and costs
  • Children generally have 12 months of continuous eligibility after approval, under the federal rule in effect since January 2024. Wyoming’s separate deemed-newborn rule provides 13 months; it is not a longer period for every young child.
  • For applications through December 2026, eligible bills can reach back three months before the application month. From January 1, 2027, the period is two months for children.
  • 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, unless you signed in advance to pay for something Medicaid does not cover.
  • For example, assume a covered, properly approved service from an enrolled hospital: the work plan allows $10,000 and pays $7,000 after a $3,000 deductible. If Medicaid’s allowed amount is $6,000, it may add $0 while the protected family balance remains $0. This illustrates billing protection, not how your insurer credits its deductible.
If you decide to apply
  1. Ask the hospital financial counselor to help with the application at wesystem.wyo.gov or 1-855-294-2127.
  2. Have current pay stubs, birth dates, insurance cards and earlier bills ready. Include any recent change in pay.
  3. Ask your hospital social worker whether a participating hospital can start temporary coverage, and discuss the separate full-application deadline.

After you apply
  • The usual decision standard is 45 days, or 90 days when a disability decision is needed. If the case is delayed, your social worker can help ask for the reason, missing information and hearing options; a request for more information does not by itself explain every delay.
  • If Medicaid says no, you have 20 business days from the date on the letter to ask for a hearing. To keep a service your child already has, ask before the change date. An out-of-state hospital also needs its own enrollment and approval.
  • Temporary coverage starts when a qualified participating hospital or clinician grants it. A full application by the end of the following month lets temporary coverage continue until that application is decided. Without that application, temporary coverage ends at that month’s end. A hospital in another state is not automatically a participating Wyoming hospital.
Good to know

Work insurance is billed first. For covered care approved by Medicaid at an enrolled clinic, billing protections can apply even when Medicaid pays nothing extra.

Other details
  • Keeping both plans means paying any remaining work premium and managing two insurers. WHIPP can consider reimbursing an active work-plan premium after Medicaid eligibility.
  • Coverage changes can affect access to the cancer team, pharmacy and planned treatment. The financial counselor can compare those before the family chooses.
Official sources
Ask your social worker

“Could Wyoming Medicaid help with treatment bills alongside our insurance? What would keeping two plans involve, and if you recommend applying, could you help with the form and earlier bills?”

Why I’m asking: I want to know whether another health plan would reduce our bills without disrupting treatment.

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 this week and report this month's income and any insurance. Name the months with old bills.

Your social worker

The oncology social worker or financial counsellor helps you file, asks the hospital about temporary coverage, and follows the decision.

The care team

Nothing is needed from the doctors for ordinary child Medicaid.

Who decides
The Wyoming Department of Health checks the income and decides. Wyoming Medicaid then pays the providers directly.
Ask your social worker
“Can you help me apply for Wyoming Medicaid today, list the bills from the last three months, and check that this hospital is enrolled with Wyoming Medicaid?”

How to apply

First step: Apply at wesystem.wyo.gov or call 1-855-294-2127 this week, and ask the hospital counsellor today whether temporary coverage can be opened.

  1. Apply at wesystem.wyo.gov or on 1-855-294-2127 this week.
  2. List the months that already have bills, so the look-back covers the admission.
  3. Ask whether the treating hospital, in or out of state, is enrolled with Wyoming Medicaid.

Official application / program page ↗

Where it starts: Apply online at wesystem.wyo.gov or call 1-855-294-2127. Ask the hospital's financial counsellor whether it can open temporary coverage the same day.

What to gather

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

How long: Wyoming publishes 45 days, 60 if more information is needed, and 90 while a disability decision is pending. No measured turnaround was published. The answer comes by post.

What a yes looks like

A letter with the coverage dates. Twelve months of coverage follow, and bills from up to three months before the month you applied can be covered.

What a no looks like, and the next move

Check whether the reason was income, a missing document or the category. Appeal by the date on the letter, and ask what happens if a parent's pay drops.

Watch out

  • Wyoming counts the tax household and this month's income, not last year's return or everyone under the roof.
  • Your child can keep private insurance and have this too. Do not cancel the work plan to apply.
  • Wyoming applies its 5 percent deduction only when it changes the answer, so apply even if you are a little over the printed figure.

Dates that change this

2026-04-01: The income limits here took effect on April 1, 2026. Wyoming publishes no standing annual date and no 2027 table was found, so check the figure with the office.

2027-01-01: Coverage can reach back up to three months before you apply now; Wyoming has announced two months for applications made on or after January 1, 2027.

2026-10-01: Wyoming has filed a change about which immigration statuses federal money will cover, proposed for October 1, 2026 and waiting on federal approval. It adds no new groups. Ask the office how it applies to your child. (not yet confirmed against the final rule)

Decisions this site cannot make: Wyoming Eligibility System income determination · Hospital presumptive eligibility, where the hospital takes part

Expect friction on: Wyoming's centres are out of state, so check the hospital takes Wyoming Medicaid before you rely on it

The trap: Wyoming counts the tax household and this month's income. The 5 percent deduction is applied only when it changes the answer, so an income between the two figures can still get a yes. Do not cancel a work plan to apply: Wyoming Medicaid pays after it.
