Missouri program

Free health insurance for your child (MO HealthNet for Kids)

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

What it is

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

MO HealthNet for Kids covers cancer care without a monthly premium. The income limit depends on your child’s age and household size. Missouri decides who belongs in that household and which income counts.

Eligibility rules
  • Your child must live in Missouri and be under 19. The state uses Medicaid household rules, including tax-filer, tax-dependent and non-filer rules; the people at your address do not automatically make up the same household.
  • The test uses current monthly income. A yearly figure divided by 12 is only an estimate.
  • From April 1, 2026 through March 31, 2027, the monthly limit for four people is $5,528 under age 1 and $4,208 at ages 1–18. The published allowance is already included.
Why families with work insurance look at this
  • Work insurance pays first. For accepted, covered care with required approvals, your private deductible, copay or coinsurance generally is not your bill—even if MO HealthNet pays $0 extra.
  • Each plan has its own rules for covered treatment. The hospital can review how both plans would handle your child’s care.
What you get
  • No premium or child copays for covered hospital stays, chemotherapy, medicines and clinic visits.
  • Dental and vision care, with separate checks for home nursing and rides.
  • Eligible earlier medical bills can also be covered.
What the help includes
  • Children receive the full MO HealthNet benefit package. Home nursing needs its own assessment.
  • For applications filed in 2026, eligible earlier bills can reach back three months before the application month. From January 1, 2027, children’s coverage reaches back two months. Eligibility must be met in each earlier month.
  • Private insurance pays first. For covered, properly authorized care accepted under your child’s MO HealthNet coverage, the enrolled clinic generally cannot bill you the private deductible, copay or coinsurance. This protection also applies when MO HealthNet pays $0 extra.
  • Noncovered care, an excluded clinic or a valid advance written private-pay agreement needs separate review. A clinic’s billing mistake does not automatically make a covered bill yours. Health-plan network, referral and approval rules still matter.
  • Worked example: the work plan allows $5,000, pays $2,000 and leaves $3,000 to your deductible. MO HealthNet's own rate is $1,500, so it pays nothing extra. The clinic writes off the $3,000 and you owe $0.
If you decide to apply
  1. Ask your hospital’s financial counselor about a MO HealthNet application through mydssapp.mo.gov or 855-373-4636.
  2. Have current income details, insurance cards and earlier bills ready. Ask whether the hospital can arrange temporary coverage.

After you apply
  • Approved children under 19 generally keep coverage for 12 months. Limited exceptions include leaving Missouri, turning 19, voluntarily ending coverage, death or an incorrect eligibility decision under the rule. The notice explains any proposed ending.
  • A decision is due within 45 days, or 90 when a disability decision is involved. Many come sooner.
  • Your social worker can help check the application date, information requests and status at 855-373-9994. If the agency does not act promptly, a hearing may be available.
Good to know

Work insurance pays first. For accepted, covered care with required approvals, the clinic generally cannot bill you the private plan’s share.

Other details
  • A qualified hospital, federally qualified health center or rural health clinic can assess temporary coverage for an otherwise eligible child. It starts on that entity’s decision date, not an earlier admission date. A full application filed by the following month’s end keeps temporary coverage open until the decision. Otherwise it ends at that month’s end.
  • The hospital can only start temporary coverage once in 12 months, and there is no appeal if it says no; the full application has its own appeal.
  • Your child's own immigration status is checked, not yours. A child without an eligible status can get emergency care covered, but not a full treatment course; ask the financial counselor for a confidential review of what applies.
  • For a managed-care denial, an appeal generally is due within 60 calendar days after the notice. Decisions take at most 30 days, or 72 hours when urgent, and faster when health requires. A limited extension of up to 14 days has additional conditions and notice requirements.
  • Continuing existing care requires a timely appeal and a separate continuation request. The request is due by the later of 10 days after the notice is sent or the proposed change date. The service must be previously authorized and clinician-ordered, with approval not expired, and the other continuation conditions must hold.
  • If the health plan says no to something, you have 60 days to appeal to the plan and then 120 days to ask the state for a hearing. To keep a service running while you appeal, ask within 10 days of the notice. The social worker can help with both. (replace items[3] to [5] with this one bullet)

Federal background: Medicaid and using Medicaid with other health insurance.

Official sources
Ask your social worker

“Could free MO HealthNet help with our child’s treatment costs? What are the benefits and drawbacks, including using it with other insurance, and would you help us apply if it fits?”

Why I’m asking: I want to understand what coverage our child could get and what bills could still reach us.

Who does what

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

You

Apply online today with this month's income and any insurance you have. Name the months that already have bills.

Your social worker

The oncology social worker or financial counsellor helps you file, asks whether a temporary approval can be opened, and chases the decision.

The care team

Nothing for ordinary child coverage. Medical records are only needed for the disability route.

Who decides
The Family Support Division checks income. MO HealthNet and the health plan you pick run the coverage.
Ask your social worker
“Can you help me file the MO HealthNet application today, and can the hospital open a temporary approval while we wait? Can we list the bills from the last three months too?”

How to apply

First step: Apply at mydssapp.mo.gov or call 855-373-9994 this week, and give this month's income rather than last year's.

  1. Apply at mydssapp.mo.gov this week and give this month's income, not last year's.
  2. List the months that already have bills so the three-month look-back covers the admission.
  3. Ask which health plan the oncology team is in before you pick one.

Official application / program page ↗

Where it starts: Apply online at mydssapp.mo.gov or by phone on 855-373-4636. Ask the hospital's financial counsellor the same week whether they can start a temporary approval.

What to gather

  • Your child's birth certificate or identity document and Social Security number
  • A Missouri 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: Missouri publishes no decision deadline. The department tells families to get in touch if nothing has arrived after 45 days. Once approved, coverage reaches back up to three months.

What a yes looks like

A notice with the dates you are covered and a choice of health plan. Check the hospital and the oncology group are in that plan before choosing. Twelve months of continuous coverage follows.

What a no looks like, and the next move

Read whether the no was about income, a document or a category. If it was income, ask in the same application about CHIP and about spend-down, and appeal by the date on the notice.

Watch out

  • The published figures already include the five-point allowance. Do not add it again and rule yourself out.
  • Your child can keep a work plan and have MO HealthNet too. Do not cancel insurance to apply.
  • Missouri changes these figures on April 1, not in January.

Dates that change this

2026-04-01: These income figures run from April 1, 2026 to March 31, 2027. Missouri refreshes them on April 1, not in January.

2027-01-01: Bills reach back up to three months before the month you apply now; two months for applications submitted on or after January 1, 2027.

2026-10-01: From October 1, 2026 Missouri says MO HealthNet and CHIP are limited to lawful permanent residents and a few other groups. Ask the Family Support Division how it applies to your child. (not yet confirmed against the final rule)

2026-09-10: Missouri publishes presumptive-eligibility income standards for children, but the list of hospitals allowed to use them is behind a password. Ask your hospital's financial counsellor directly. (not yet confirmed against the final rule)

The numbers and the rules

The arcane layer, kept on purpose. Checked September 11, 2026.

The eligibility facts, as published

Age
under 19
Age max exclusive
19
Income
MAGI budget group; base lines 196% of poverty under age 1 and 148% from 1 to 18, with a five-percentage-point disregard already applied in the published dollar cells
Insurance status condition
none on the Non-CHIP side: private insurance is billed first and MO HealthNet pays second
Residency
Missouri
Continuous eligibility
12 months for children
Retroactive months
up to 3 now; 2 for applications submitted on or after 2027-01-01
Processing standard
unknown: no state promptness rule was found. The department says to contact it after 45 days.

The trap: The published monthly figures already include the five-percentage-point allowance, so do not add it twice. Being insured does not shut the door: a child who cannot be in CHIP because they are insured goes into Non-CHIP instead. Do not cancel a work plan to apply.
