I am enrolled as a participating provider in another state’s Medicaid program. Am I also required to enroll in Delaware’s Medicaid Program to provide services to Medicaid beneficiaries?

Yes. Providers must enroll with DMAP to receive reimbursement for Delaware Medicaid Services.

How do I enroll?

Navigate to the State of Delaware Provider Enrollment portal and complete an online application. Providers with more than one Provider Service/Practice Location will have a separate DMAP account for each location.

Note: High Risk providers must successfully enroll in Medicare prior to enrolling with DMAP.

How does my registration relate to billing for services?

You must register with the state using the same identifiers you plan to bill with, i.e. TIN/SSN, Specialty, etc.

*The following items must be in alignment:

  • Your contract with Envolve / Centene Dental and Vision
  • State Registration
  • Billing Set Up / Configuration

Are there additional requirements and screenings based on risk / risk level?

According to CMS/Medicaid:

Requirements by Risk Level:

All Risk Levels:

  • Verify provider meets any applicable Federal regulations or State requirements for the provider type prior to making an enrollment decision.
  • License Verifications.
  • Conduct Database checks.

Limited Risks:

  • Site visit.

High Risks:

  • Any provider that has a payment suspension based on a credible allegation of fraud within the last 10 years.
  • Any provider excluded within the past 10 years by HHS-OIG or a State Medicaid Agency (SMA).
  • Any provider that has a qualifying Medicaid overpayment.
  • The provider is enrolling within 6 months of the date of the lifting of a temporary moratorium that at the time would have barred the provider’s enrollment.

*According to the State of Delaware, High Risk providers must successfully enroll in Medicare prior to enrolling with DMAP.

*States may impose additional screening methods “in addition to or more stringent than” those in the regulations. This could result in a change in the risk category assigned for certain types of providers. Providers should check with their SMA to determine their risk category.

Additional requirements based on Provider’s assigned risk level can be found on the "Delaware Medical Assistance Portal for Providers."

What is the enrollment application processing timeframe?

According to the state, enrollment applications will be reviewed by DMAP, and the expected turnaround time is within fifteen (15) business days.

What is my Enrollment Effective Date? / How is my Enrollment Effective Date Determined?

According to the Delaware Medical Assistance Program, the enrollment effective date will be located on the provider’s Welcome Letter. The state does not provide information on how enrollment effective date is terminated.

How do I find proof of registration?

Upon acceptance of your enrollment, you will receive a Welcome to DMAP Letter with the effective date for the enrolled Provider Service/Provider Practice Location.

Note: If enrolled in more than one Provider Service/Practice Location, you will receive a Welcome Letter for each location.

I am enrolled but recently received a letter from the State saying that I need to re-enroll, re-register, or revalidate my information. What do I need to do?

Navigate to your DMAP Portal account to complete your revalidation.

Note: The PIN for the provider's Portal can be found on page 2 of the provider’s Welcome Letter.

How often do I need to re-enroll, re-register, or revalidate my information?

Revalidation: Providers are required to submit updated information at least every five (5) years, if not more frequently to ensure the provider meets required standards for continued enrollment in DMAP.

Providers enrolled in DMAP will automatically receive a sixty (60) day notice to revalidate in DMAP at a minimum of every 5 years.
