Where to start your Colorado Medicaid application

You apply for Colorado Medicaid through the state's Department of Human Services, specifically through a system called PEAK (Program may be able to access and Application Kit). PEAK is Colorado's online portal where you submit your application, upload documents, and check your status. You can also apply by mail, phone, or in person at your county human services office, but the online route is usually fastest.

Before you start, gather your Social Security number, proof of income (recent pay stubs, tax returns, or a letter from your employer), proof of residency (utility bill or lease), and identification. If you're applying for a child or dependent, you'll need their information too. Having these documents ready before you log in cuts your application time in half.

The application itself asks about your household size, income, citizenship status, and whether you're pregnant, disabled, or caring for dependents. Colorado uses these answers to determine which Medicaid program you might fit into — some programs have income limits, others don't. The system will tell you during the application whether you appear to meet the basic requirements.

Key Takeaways

  • Apply through PEAK online at peak.colorado.gov, by phone at 1-844-CO-PEAK-1, or at your county human services office.
  • Have your Social Security number, recent income proof, residency proof, and ID ready before you start the application.
  • Colorado Medicaid covers different income levels depending on which program you're in — parents, children, pregnant people, and disabled adults have separate rules.
  • After you submit, the state typically makes a decision within 30 days, though complex cases can take longer.
  • If you're denied, you have the right to request a hearing and present more information to appeal the decision.

Income limits and which program you might fit into

Colorado Medicaid has several separate programs, and which one you can enter depends on your household income and your situation. For example, parents and caretakers have one income limit, children have another (usually higher), and pregnant people have a third. Disabled adults and seniors have different rules still. The income limits change each year, so the exact number depends on when you apply.

During your PEAK application, the system will show you which programs you might be may be able to access for based on what you enter. You don't have to choose — the state determines which program fits your situation. If your income is above the limit for one program but below it for another, you'll be placed in the one that covers you. If you're above all limits, you'll be denied, but you can reapply if your income drops or your situation changes.

Colorado also has a program called the Health Insurance Affordability Fund that covers people who don't fit into standard Medicaid but still need help. This program has its own income rules and is sometimes easier to enter. PEAK will tell you if you might be may be able to access for this during your application.

What documents you need to upload or bring

The state needs proof of everything you claim on your application. For income, that usually means recent pay stubs (last 30 days), a tax return from the past year, or a letter from your employer on company letterhead stating your hourly rate and hours per week. If you're self-employed, bring your last two years of tax returns. If you receive unemployment, Social Security, or other benefits, bring the award letter or a recent statement showing the amount.

For residency, a utility bill, lease agreement, or mortgage statement with your name and current address works. The document needs to be dated within the last 60 days. If you're homeless or don't have a permanent address, you can still apply — tell PEAK this during the application and bring any document with your name on it, even if the address is old.

If you're applying for a child, you'll need their birth certificate or Social Security card. If you're applying as a caretaker for someone else, bring proof of your relationship — a birth certificate if it's your child, a custody order if it's not. Upload these documents directly into PEAK if you're applying online, or bring them to your county office if you're applying in person.

How long the decision takes and what happens next

After you submit your application, Colorado has 30 days to make a decision. In practice, many decisions come back within two weeks if your documents are clear and your situation is straightforward. If the state needs more information, they'll send you a notice asking for it — you'll have 10 days to respond. If you don't respond, your application will be denied, but you can reapply anytime.

Once you're approved, you'll receive a notice in the mail telling you which Medicaid program you're in and when your coverage starts. Coverage usually begins the first day of the month you applied, or sometimes the first day of the following month depending on when in the month you applied. You'll also get information about how to choose a health plan if your program requires it.

If you're denied, the notice will explain why. Common reasons include income above the limit, not meeting the citizenship requirement, or missing documents. You have the right to request a hearing within 30 days of the denial notice. At the hearing, you can present new information or explain why you think the decision was wrong. Many people win on appeal by bringing documents they didn't have when they first applied.

Applying online through PEAK versus other methods

PEAK (peak.colorado.gov) is the fastest way to apply because you get an immediate confirmation that your application was received, and you can check your status anytime by logging back in. You can also upload documents directly, which means the state sees them right away instead of waiting for mail. If you have email, you'll get updates about your application status automatically.

If you don't have internet access or prefer to talk to someone, call 1-844-CO-PEAK-1. The phone line can take your application over the phone, though it takes longer than online. You'll still need to mail or bring documents to prove what you said. Wait times can be long, especially early in the month.

You can also walk into your county human services office and apply in person. This is useful if you need help understanding the questions or if you have complicated documents to explain. County offices are listed on the Colorado Department of Human Services website. Applying in person means someone can answer questions immediately, but you may have to wait for an appointment.

What to do if your income or situation changes

You're required to report changes to your income, household size, or address within 30 days. You can report changes through PEAK, by phone, or at your county office. If your income goes up and you're no longer may be able to access, your coverage will end on the last day of the month you report the change. If your income goes down, you might move into a different Medicaid program with better benefits.

If you have a baby, get married, move, or lose a job, report it right away. These changes can affect your may be able to access or which program you're in. If you don't report changes and the state finds out later, you might have to repay benefits you weren't supposed to receive, though Colorado is usually lenient about this if you report the change yourself.

Your Medicaid coverage is not permanent — the state reviews your case every year. You'll receive a notice asking you to renew. If you don't respond to the renewal notice, your coverage will end. Renewal is usually simpler than the first application because the state already has most of your information.

Special situations: pregnancy, disability, and citizenship

If you're pregnant, Colorado has a separate Medicaid program with higher income limits than regular adult Medicaid. You can apply anytime during pregnancy, and coverage can start retroactively to the first day of the month you became pregnant. Pregnancy-related Medicaid covers prenatal care, delivery, and postpartum care for 60 days after birth. After that, you'll need to reapply for regular Medicaid if you still meet the income limit.

If you're disabled or have a chronic condition, you may be may be able to access for Medicaid even if your income is higher than the regular limit. You'll need medical documentation — records from your doctor, hospital, or mental health provider showing your condition. During your PEAK application, there's a section to indicate if you're disabled. If you say yes, the state will ask for medical proof.

You must be a U.S. citizen or a may have access to immigrant to get Colorado Medicaid. may have access to immigrants include people with a green card, refugees, asylees, and some other visa holders. If you're not sure whether you may have access to, bring your immigration documents to your county office and ask. The state cannot share immigration information with federal authorities, so applying won't put your status at risk.
