How to apply for Mississippi Medicaid

The Mississippi Division of Medicaid (DOM) accepts applications through its website, by phone, and in person at regional offices. Per DOM's "How to Apply" page, the application covers children, pregnant women, low-income parents of children under 18, and other qualifying household members.

What you need to apply

DOM verifies identity, Mississippi residency, income, household composition, and citizenship or immigration status. The documents below apply to most applicants.

• Full legal name and date of birth for all household members applying
• Social Security numbers for all applicants
• Proof of Mississippi residency — utility bill, lease, bank statement, or official mail
• Income verification — recent pay stubs, employer statement, or tax return if self-employed
• For parents/caretaker relatives: documentation showing children's presence in the household
• For pregnant women: medical documentation of pregnancy from a provider
• Immigration documents for non-citizen applicants
• For nursing home or HCBS waiver applications: medical records and physician statement required

How long does a Mississippi Medicaid application take?

Under 42 CFR 435.912, Mississippi must process most MAGI-based applications (children, pregnant women, parents) within 45 days. Applications for aged, blind, and disabled categories — which involve non-MAGI financial review and functional assessments — may take up to 90 days.

Coverage usually begins the first of the month you applied, if approved. Pregnant women may request retroactive coverage up to three months before the application date.

DOM sends correspondence by mail to the address on file. Keep your address current — missing a notice is a common reason coverage lapses at renewal. Report address changes through the MESA portal or by calling 1-800-421-2408.

What documents you'll need

Gather these before starting your application. Having them ready prevents delays caused by missing information requests, which can add weeks to the review.

• Proof of identity — driver's license, state ID, passport, or birth certificate
• Proof of residency in Mississippi — utility bill, lease, or official mail with your address
• Social Security numbers for all household members applying
• Proof of income for the past 30 days — pay stubs, employer letter, or benefit award letters
• Tax filing information if self-employed — prior year return is typically acceptable
• Immigration documents if applicable — green card, visa, or I-94 arrival/departure record
• Health insurance information if you currently have coverage through an employer or other source

Not every document is required for every applicant. The application will specify what Mississippi Medicaid needs based on your household composition.

The application process, step by step

1. 1

   Gather your documents

   Collect proof of identity, residency, income, and household composition before you start. Having everything ready means you can complete the application in one sitting.

2. 2

   Submit the application

   Apply through your preferred method — online is fastest. The application asks about income, household size, citizenship status, and whether anyone in the household has other insurance. Answer completely to avoid requests for more information.

3. 3

   Respond to any follow-up requests

   Mississippi Medicaid may request additional documents or clarification. Respond promptly — delays in providing information can pause or restart the review clock.

4. 4

   Receive your eligibility notice

   The agency will send a written notice of approval or denial. If approved, the notice will state your coverage start date and what benefits you're eligible for.

What to expect after you apply

Under 42 CFR 435.912, states must process most Medicaid applications within 45 days of receipt. Applications based on disability take up to 90 days. If Mississippi hasn't issued a decision by those deadlines, the agency must notify you in writing with the reason for delay.

Medicaid coverage typically starts on the first day of the month in which you applied, assuming you're determined eligible. In some cases — particularly for pregnant women — retroactive coverage going back up to three months may apply if you received qualifying medical services during that period.

Keep your contact information updated while your application is pending. A notice sent to an old address counts as received.

If your application is denied

A denial notice must state the specific reason and your right to appeal. You have the right to request a fair hearing — typically within 90 days of the denial notice — where you can present evidence and contest the decision before an impartial hearing officer.

Common denial reasons include income above the limit, failure to verify documents within the required timeframe, or a missing signature. Many denials can be resolved by reapplying with the correct documentation.
