Enroll — new baby

Health insurance after having a baby in Colorado

Updated for plan year 2026

An honest page about covering a new baby has to say this early: the best coverage for your child may not be your plan at all. Medicaid and the Children's Health Insurance Program cover kids at household income levels well above the cutoffs that apply to adults, so plenty of households earn too much for any help themselves and still qualify the baby for free or low-cost coverage. Reporting the birth on your Connect for Health Colorado application checks this automatically. And one rule is stronger still: if the mother has Medicaid when the baby is born, the newborn is enrolled automatically and stays eligible for at least a year.

A mixed household — parents on a marketplace plan, baby on CHIP or Medicaid — is normal, common, and often the cheapest sound arrangement. If the baby belongs on your plan instead, you have 60 days from the birth, adoption, or foster placement, with coverage retroactive to the date of the event. Colorado's multiple plans from participating insurers price below.

Everyone on your tax return, covered or not.

Before going further, make sure the income you entered is the income that counts. The marketplace uses modified adjusted gross income for your household: wages, self-employment net profit, unemployment compensation, severance, plus a few add-backs like tax-exempt interest and the non-taxable portion of Social Security. It does not include SNAP benefits, child support you receive, or gifts. And it covers the full calendar year — the months already earned plus the months ahead, not a snapshot of this month multiplied by twelve. Getting the definition right matters twice. It sets the estimate above, and at tax time the marketplace's advance payments get reconciled against the real figure — overshoot your guess and money comes back to you, undershoot and you owe the difference. If the figure you typed was rough, refine it before you enroll on Connect for Health Colorado; the sections below assume the number is solid and build the plan decision on top of it. Five careful minutes here protects both your monthly budget and next spring's tax return. If you share finances with anyone, do this part together. Household income means everyone on the tax return — a spouse's wages included — and the most common correction households make is adding income somebody forgot to count. Better that addition comes from you, now, than from the reconciliation later.

The marketplace in Colorado

Colorado runs its own exchange, Connect for Health Colorado — that is where you compare plans and enroll.

Colorado expanded Medicaid, so if your household income falls below about 138% of the federal poverty level you likely qualify for free or very low-cost coverage — check the state Medicaid office before buying a marketplace plan. The next open enrollment window runs from November 1, 2026 to December 31, 2026. This state has historically extended enrollment into January; under the 2025 federal rule (unstayed), PY2027 enrollment must end by Dec 31, 2026. Final dates not yet announced — based on the legal maximum.

A worked example

A couple with a newborn earning $66,600 a year — about 250% of the federal poverty level — their estimated subsidy against a typical Silver benchmark in Colorado is $89/month. Colorado runs its own exchange, so this is a state-average estimate — rougher than the figures for federal-marketplace states.

Your number depends on your actual income, household, and ZIP — run it above.

How to enroll in Colorado

  1. 01

    Check your window

    This qualifying event opens a special enrollment period: you have up to 60 days after it to pick a plan — there is no apply-ahead window. Miss it and you generally wait for the next open enrollment.

  2. 02

    Gather your documents

    Same notice-driven process as other life events: after applying, your Marketplace Eligibility Notice tells you whether you must submit documents — you have 30 days after picking a plan to send them, and coverage can't be used until eligibility is confirmed and the first premium is paid. For adoption, foster care placement, or a court order, HealthCare.gov publishes the acceptable documents: an adoption letter or record signed by a government or court official, foster care papers signed by a government or court official, a child support or other court order, a legal-guardianship document, a medical support order, or (for foreign adoptions) a DHS immigration document — each showing the dependent's name and the date they became a dependent; a letter of explanation can be submitted if none are available. HealthCare.gov publishes no separate acceptable-documents list specifically for a birth.

  3. 03

    Estimate your income honestly

    Your subsidy is based on what you expect to earn this calendar year, not last year — estimating low means repaying the difference at tax time. Use the calculator above to see your number first.

  4. 04

    Apply at Connect for Health Colorado

    Enroll through Connect for Health Colorado, or by phone at 1-855-752-6749.

  5. 05

    Pick by total cost, not premium

    The real annual cost is premium plus deductible, copays, and coinsurance — a cheaper-premium plan can cost more overall if you use care.

Coverage starts the day the baby was born (or the day of the adoption or foster care placement) — retroactive even if you pick the plan up to 60 days later. If you'd rather not pay premiums back to the birth date, HealthCare.gov says you can call the Marketplace Call Center to request that your coverage start later; under the federal effective-date rules (45 CFR 155.420(b)(2)(i)) the Exchange may let you elect the first of the month following plan selection or a regular prospective date instead.

Adding a baby, switching plans, or both — honestly

If anyone in the household can get coverage through a job, the marketplace is only half the comparison, and the honest version of this page prices both halves. Federal rules give job-based plans their own special enrollment when you gain a child: the plan must allow at least 30 days after a birth, adoption, or placement for adoption to request enrollment, and coverage takes effect from the date of birth — the same retroactive protection the marketplace offers. The employee, and often the spouse, can usually come aboard in the same enrollment, not just the baby.

The two paths differ in ways that decide real money. The work plan typically carries an employer contribution, which is hard to beat when it's generous. The marketplace plan carries the subsidy, which just got bigger for many families — household size rose, so the same income measures lower against the poverty level. And the windows differ materially: at least 30 days at work versus 60 on the marketplace, both counted from the event. The work-plan clock expires first; if that option is in the running at all, get its quote first.

One interaction deserves care: an affordable offer of job-based coverage generally ends marketplace subsidy eligibility for the people it covers. If the work plan's family coverage meets the affordability rules, the subsidized-marketplace route may simply be off the table for the household, however attractive the estimator's number looks. The marketplace application asks about employer offers and applies the test for you — answer it exactly as written rather than guessing.

How to run the comparison in one evening: get the work plan's price for the new family tier and its deductible; run the estimator above for Colorado's side — multiple plans from participating insurers, benchmark silver at around $557 — using the new household size; then compare total yearly cost, not premiums alone. Either answer can win. The only losing move is letting the 30-day clock decide by lapsing while the comparison waits.

What to watch out for

Coverage that starts the day the baby arrived

This event carries the most generous start date in the marketplace: enroll any time within the 60-day window and coverage takes effect retroactively on the date of the birth, adoption, or foster placement. The baby's earliest weeks — the most medically attended of all — end up inside the plan even if the enrollment happened later. The corollary is that premiums run from that date too, so a late enrollment settles the intervening weeks' premiums at signup. If the back-payment doesn't suit you, you can ask Connect for Health Colorado about starting coverage later instead, generally the first of the month after you pick a plan.

Already enrolled? The window is about the baby

If you have a marketplace plan, the birth doesn't reopen the family's plan choice. The options are: keep your plan and add the baby to it, or enroll the baby in any plan of their own for the rest of the year. The rest of the household generally keeps its coverage until open enrollment — a few state-run marketplaces are more flexible, so ask Connect for Health Colorado rather than assuming in either direction. What every enrolled household should still do: report the birth promptly, because the household-size change refigures the savings on the plan you already have.

Report the birth even if you change nothing

A new household member belongs on your application whether or not any plan changes. The subsidy formula compares income to the federal poverty level for your household size, and gaining a member can mean more savings than you're getting now — the recalculation only happens when you report. The same update screens the baby for Medicaid and CHIP eligibility automatically. Skip the report and you're paying the old, smaller-household price for the rest of the year, then settling any difference through the tax return rather than your monthly premium.

CHIP and Medicaid take children at higher incomes

Children's eligibility for Medicaid and CHIP reaches well above the income cutoffs that apply to adults, so a household that qualifies for little or no marketplace help can still get the baby free or low-cost coverage. The result — parents on a marketplace plan, baby on a children's program — is a normal, common arrangement, not a fallback. Both programs run year-round with no enrollment window. And one rule is automatic: if the mother has Medicaid when the baby is born, the newborn is enrolled in Medicaid and stays eligible for at least a year.

No window opens before the birth

Pregnancy by itself generally isn't a qualifying life event — the birth is — so there's no enrolling ahead of the due date through this window. A pregnant household's marketplace paths are open enrollment, November 1, 2026 to December 31, 2026, or a different qualifying event along the way; any plan picked then covers pregnancy and childbirth from the day it starts, since pregnancy can't be treated as a disqualifying pre-existing condition. A small number of states run their own pregnancy rules — Connect for Health Colorado can tell you whether yours is one of them.

Documents, if your notice asks

Paperwork is requested only when your eligibility notice says so, and you have 30 days after picking a plan to submit — picking is what stops the enrollment clock, so never wait on documents to enroll. For adoption, foster care, or a court order, the published list is specific: adoption letters or records, foster care papers signed by a government or court official, court orders, legal-guardianship documents, or medical support orders, each showing the child's name and the date they became your dependent. For a birth there's no separately published list; a letter of explanation can stand in if nothing else fits.

Mistakes people make

Treating the birth as a chance to re-shop everything

A new baby generally doesn't reopen plan choice for an already-enrolled household. The window adds the baby to the plan you have, or gives the baby a plan of their own — the rest of the family keeps its coverage until open enrollment. Families burn weeks of the 60-day window pricing a household switch that mostly isn't on the menu. Spend the time on the real choices: your plan versus the baby's own plan versus CHIP.

Waiting for life to settle first

The window runs 60 days from the birth, adoption, or placement — not from when the household starts sleeping again. Because coverage is retroactive to the event, enrolling late inside the window costs nothing; lapsing past it costs the window entirely, and the wait runs to open enrollment. Put day 60 on the calendar the week you're home and treat one quiet evening as the whole task.

Counting on the due date to open a window

Pregnancy by itself generally isn't a qualifying event — the birth is what starts the clock. Households that wait to enroll until the pregnancy is confirmed, expecting a window, find none open until the baby arrives. If you're pregnant and uninsured, the moves are open enrollment, a different qualifying event, or checking Medicaid — which has no window and, in many states, covers pregnancy at higher income levels.

Skipping the household update

Not reporting the birth leaves the subsidy running on last month's smaller household — usually an undercount of the help you now qualify for, paid for in real monthly dollars. The report takes minutes, frequently lowers the premium on the plan you already have, and screens the baby for Medicaid and CHIP at the same time. It also keeps the advance credit honest for the tax-time reconciliation, which checks the household you actually had.

Paying sticker for the baby without the CHIP check

Children qualify for Medicaid and CHIP at household incomes well above the adult cutoffs, and the screening happens automatically when you report the birth. Families who skip the report and simply add the baby to their plan can pay months of premium for coverage the child qualified to get free or nearly free. Check first — the answer arrives with the application update, and the marketplace plan remains available if CHIP says no.

Frequently asked questions

What if I missed the 60-day deadline?

You generally wait for open enrollment, which runs November 1, 2026 to December 31, 2026 for coverage starting next year. The exceptions are other qualifying life events — getting married, having a baby, moving to a new coverage area, or losing other qualifying coverage — each of which opens its own enrollment window. In the meantime, check whether you qualify for Medicaid, which has no enrollment deadline, and know that any care you get while uninsured is billed at full price.

How are marketplace subsidies actually calculated?

The subsidy is the gap between a benchmark premium and what the law says your household should pay. The marketplace finds the second-lowest-cost silver plan in your area — the benchmark — and caps your share of it at a percentage of your income that rises with earnings. The difference is your premium tax credit, and you can apply it to any metal tier, not just silver. In Colorado, the benchmark for a 40-year-old runs around $557 a month before subsidies, which is why the same plan costs different households very different amounts.

What counts as income for marketplace subsidies?

Modified adjusted gross income for your household: adjusted gross income from your tax return, plus tax-exempt interest, untaxed foreign income, and non-taxable Social Security benefits. In practice that means wages, self-employment profit, unemployment compensation, severance, investment income, and retirement distributions all count; SNAP benefits, child support received, and gifts don't. It's the expected total for the calendar year across everyone on your tax return — not your income this month, and not just the applicant's.

What's the difference between bronze, silver, and gold plans?

The split between premium and out-of-pocket costs. Bronze plans have the lowest premiums and the highest deductibles; gold (and platinum, where offered) reverse that; silver sits between. The metal says nothing about care quality or network size — those vary plan by plan. Silver has one special property: if your income qualifies, extra cost-sharing reductions apply only to silver plans, lowering deductibles and copays substantially. Among the multiple plans in Colorado, compare total annual cost — premiums plus expected care — rather than premium alone.

Do marketplace plans cover pre-existing conditions?

Yes, all of them. Every marketplace plan must cover treatment for conditions you had before enrolling, can't charge you more for them, and can't refuse to sell to you because of them. Pregnancy is covered from the day your plan starts, even if it began earlier. This is a legal requirement, not a plan feature to shop for — which means the real comparison points are premiums, deductibles, networks, and drug lists, where plans genuinely differ.

When is open enrollment in Colorado?

Open enrollment runs November 1, 2026 to December 31, 2026 for coverage starting next year, through Connect for Health Colorado. Note that these windows are shorter than in past years — federal rules tightened enrollment deadlines starting with 2027 coverage, so a January deadline you remember may no longer exist. Outside the window, you need a qualifying life event — losing coverage, marriage, a move, a birth — to enroll. If one applies to you, you don't have to wait.

What if my income lands near the Medicaid cutoff?

Apply and let the application sort it out — Colorado expanded Medicaid, so the marketplace checks your estimate against the 138-percent-of-poverty threshold and routes you to Medicaid or a subsidized plan accordingly. If your income moves across the line mid-year, report it: people shift between Medicaid and marketplace coverage as income changes, and both directions are normal. Don't shade your estimate to land on the side you prefer; the reconciliation on your tax return trues up subsidy dollars either way.

Are subsidies the same on a state marketplace?

Yes. The premium tax credit is federal law, calculated the same way whether you enroll through HealthCare.gov or through Connect for Health Colorado — the same income rules, the same benchmark math, the same reconciliation on your federal tax return. What a state marketplace can add is more, not less: some states fund extra savings on top of the federal subsidy, and Connect for Health Colorado is where any such program would show up in your quote. Enroll through Connect for Health Colorado; quotes elsewhere won't include state-specific help.

Does having a baby qualify me for a special enrollment period?

Yes. A birth, adoption, or foster care placement opens a 60-day enrollment window through Connect for Health Colorado, counted from the date of the event — and coverage can start retroactively on that date, the most generous start any qualifying event gets. If you already have a marketplace plan, the window lets you add the baby or give the baby a plan of their own; if the household is uninsured, everyone can enroll together.

When does coverage start for a new baby?

On the day of the birth, adoption, or foster placement — retroactively, even if you pick the plan up to 60 days later. Premiums run from that same date, so a later enrollment settles the back weeks at signup. If you'd rather not pay back to the event, you can ask Connect for Health Colorado about a later start instead, generally the first of the month after you pick a plan.

Can I enroll in a marketplace plan because I'm pregnant?

Generally no — pregnancy by itself isn't a qualifying life event in most states; the birth is what opens the window. While pregnant, your paths are open enrollment (November 1, 2026 to December 31, 2026) or a different qualifying event, and any plan you get covers pregnancy and childbirth from its start date. A small number of states treat pregnancy itself as qualifying — ask Connect for Health Colorado about yours. Medicaid is also worth checking; it has no enrollment window.

How do I add my baby to my marketplace plan?

Report the birth on your Connect for Health Colorado application and add the baby to your current plan — you keep the plan, the baby joins it, and coverage for the baby reaches back to the birth date. The household-size change also refigures your savings, often favorably. You have 60 days from the birth to make the enrollment change, and the same update screens the baby for Medicaid and CHIP.

If a work plan is anywhere in this decision, sequence by the shorter clock. Job-based plans must give you at least 30 days after a birth or adoption to add the child — half the marketplace's 60 — and both windows started on the same day. So get the employer quote first: the family-tier premium, the deductible, what the employer contributes. Then run the marketplace side through the estimator above, remembering that your subsidy was just refigured for a bigger household — and that an affordable employer offer generally ends subsidy eligibility for those it covers; the application checks this if you answer its employer-coverage questions exactly as written. Both paths share the retroactive start, so the baby is protected from the event date under either. What differs is money and time. Compare total yearly cost, decide before day 30 while both doors are open, and enroll through Connect for Health Colorado only if the marketplace actually won the comparison — this page can live with either answer.
