Where to start your Medicaid application in New Mexico

In New Mexico, you apply for Medicaid through the Human Services Department (HSD), which runs the program statewide. You can start an application in three ways: online through the New Mexico PEAK portal (peaknm.org), by phone at 1-888-997-9492, or in person at your local HSD office. The online portal is usually the fastest route because you get an immediate confirmation number and can upload documents right away.

Before you start, gather these documents: proof of identity (driver's license, passport, or tribal ID), proof of New Mexico residency (utility bill, lease, or mail from a government agency), proof of income (pay stubs, tax returns, or a letter from your employer), and Social Security numbers for everyone in your household. If you do not have all of these, you can still begin the application — HSD will tell you what else they need.

The application itself asks about your household size, income, citizenship or immigration status, and any medical conditions that might may have access to you for expedited processing. Be honest about everything, because HSD verifies income and residency through state records and other agencies. If information does not match, they will ask you to clarify or provide additional proof.

Income limits and what counts as income

New Mexico Medicaid income limits depend on your household size and which program you are in. For adults without children, the limit is roughly 138% of the federal poverty line (about $1,900 per month for a single person in 2024, though this changes yearly). For parents and children, limits are higher. For seniors and people with disabilities, different rules apply — some programs have no income limit at all.

When HSD calculates your income, they count wages, self-employment earnings, Social Security, unemployment benefits, and child support you receive. They do not count food stamps, housing assistance, or most tax refunds. If you are self-employed, bring your last two years of tax returns and a profit-and-loss statement for the current year. If your income varies month to month, HSD averages it over the past three months.

If your income is slightly over the limit, you may still may have access to through a work incentive program or a special category. Tell HSD about any work-related expenses, childcare costs, or medical bills you pay — these can lower your countable income. If you are unsure whether you are over or under, apply anyway; HSD will calculate it and tell you the result.

Proof of citizenship and immigration status

New Mexico requires proof that you are a U.S. citizen or a may have access to immigrant to receive Medicaid. Acceptable proof includes a birth certificate, passport, naturalization papers, or a tribal enrollment card. If you were born outside the U.S., bring your green card or employment authorization document (EAD).

If you are undocumented, you do not may have access to for regular Medicaid, but New Mexico offers emergency Medicaid for urgent medical conditions regardless of immigration status. You can also look into community health centers, which provide care on a sliding fee scale based on income. Some nonprofits in your area may also help cover costs.

HSD will not report immigration status to federal immigration authorities as part of the Medicaid application process. Your application information is confidential and used only to determine Medicaid status.

What happens after you submit your application

Once HSD receives your application, they send you a confirmation letter with a case number. This letter tells you what documents they still need, if any. You have 30 days to send missing documents — you can mail them, upload them to PEAK, or bring them to your local office.

HSD then verifies your information against state wage records, Social Security Administration data, and the state's immigration database. This usually takes 10 to 20 days. If everything matches, you get a decision letter in the mail. If something does not match, HSD calls or sends a notice asking you to explain or provide more proof.

Standard processing takes 30 days from the date HSD receives a complete application. If you report a medical emergency, are homeless, or are a child, HSD processes your application in 7 days. If you are approved, your coverage starts on the first day of the month you applied or the first day of the next month, depending on when your application was complete.

Renewing your Medicaid coverage

New Mexico Medicaid coverage lasts 12 months. About 30 days before your coverage ends, HSD mails you a renewal form. You can renew online through PEAK, by mail, by phone, or in person. The easiest method is online, because you get immediate confirmation.

When you renew, HSD asks for updated income information and household changes. If nothing has changed, you can often renew without sending new documents — HSD will verify your income using state records. If your income has changed, bring recent pay stubs or a letter from your employer.

If you miss the renewal deadline, your coverage ends. You can reapply at any time, but there is no coverage gap protection — you will have uninsured days. To avoid this, renew before your deadline or call HSD if you need an extension.

Special programs and expedited processing

New Mexico has several Medicaid programs beyond standard coverage. Medicaid for Pregnant People covers pregnant women and new mothers for 12 months after birth, regardless of income. Medicaid for Children covers children up to age 19 with higher income limits than adults. Medicaid for Seniors and People with Disabilities has different rules and may cover long-term care.

If you are homeless, pregnant, have a serious medical condition, or are a child, HSD processes your application in 7 days instead of 30. To request expedited processing, tell HSD when you apply or call 1-888-997-9492 and explain your situation. You do not need a doctor's letter — your statement is enough to start the faster process.

If you are working and earn too much for regular Medicaid, ask about the Medicaid Buy-In Program, which lets working people with disabilities keep Medicaid even if their income exceeds the limit. You pay a small monthly premium, but you keep your coverage and work incentives.

If your application is denied

If HSD denies your application, they send you a letter explaining why. Common reasons include income over the limit, missing proof of citizenship, or residency in another state. The letter tells you exactly what did not meet the requirement and how long you have to respond.

You have 30 days from the date of the denial letter to request a hearing. You do not need a lawyer. At the hearing, you can present new documents, explain your situation, or challenge HSD's decision. You can also submit written evidence instead of attending in person. Request the hearing by calling 1-888-997-9492 or mailing the form that came with your denial letter.

While you wait for a hearing, you can reapply if your situation has changed — for example, if your income dropped or you found proof of residency. A new application starts the process over and may result in approval before your hearing date.
