How to apply for Delaware Medicaid

Delaware DMMA accepts applications online, by phone, and in person at DHSS offices. Delaware is a small state with a limited number of DHSS office locations — the online portal at assist.dhss.delaware.gov is often the most convenient option. Per DMMA, you can apply even if you have a car, bank account, and a home — Delaware does not use an asset test for standard Medicaid.

What you need to apply for Delaware Medicaid

Per DMMA, Delaware does not look at assets when determining Medicaid eligibility. Income, residency, and citizenship/immigration status are the primary factors. Prepare the following before applying.

• Full legal name and date of birth for all household members applying
• Social Security numbers for all applicants
• Proof of Delaware residency — utility bill, lease, or official mail with current address
• Income documentation — pay stubs from the past 30 days, self-employment records, or benefit award letter
• Immigration documents for non-citizen applicants
• Current health insurance information if anyone in the household has existing coverage
• For nursing facility or long-term care applications: physician documentation and financial disclosure

How long does a Delaware Medicaid application take?

Federal rules (42 CFR 435.912) require Delaware to process most applications within 45 days. Disability-related applications may take up to 90 days. Coverage begins on the first day of the month you applied, if approved.

Per DMMA, Delaware also offers retroactive eligibility — coverage can go back up to three months before the application date for qualifying members. Ask about retro-eligibility when you apply if you have outstanding medical bills from recent months.

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 Delaware — 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 Delaware 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

   Delaware 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 Delaware 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.
