# Maryland Medicaid Enrollment: Active ID, Paid Claims > Maryland Medicaid enrollment in 2026: the December 31, 2026 backdate deadline, what the application hold meant, and the 5 year revalidation window. Source: https://webillhealth.com/maryland-medicaid-provider-enrollment/ Publisher: WeBill Health Last updated: November 4, 2026 Maryland Medicaid ## Maryland Medicaid, enrolled in time and paid An active Maryland Medicaid ID, a start date backdated where allowed, and revalidation finished on schedule. [Request a Revenue Defense Audit](https://webillhealth.com/revenue-defense-audit/request/) Maryland Medicaid enrollment, revalidation and updates are filed through [MPRIME](https://health.maryland.gov/mmcp/provider/Pages/enrollment.aspx), which the department’s [October 2026 provider enrollment FAQ](https://health.maryland.gov/mmcp/provider/Documents/Maryland-Medicaid-Provider-Enrollment-FAQ.pdf) says replaces its predecessor on October 13, 2026. * Revalidation cycle Revalidation is required every 5 years for all Maryland Medicaid providers to remain enrolled and in good standing. [Maryland Medicaid Provider Enrollment FAQ](https://health.maryland.gov/mmcp/provider/Documents/Maryland-Medicaid-Provider-Enrollment-FAQ.pdf) * Revalidation window Notices come 90, 60 and 30 days from the revalidation due date, and providers have 90 days from the due date to complete the application before the account is suspended. [Maryland Medicaid Provider Enrollment FAQ](https://health.maryland.gov/mmcp/provider/Documents/Maryland-Medicaid-Provider-Enrollment-FAQ.pdf) * Backdated start date A newly enrolling provider that submits a complete and processable application by December 31, 2026 is eligible for a backdated enrollment effective date. [Maryland Medicaid, June 2026 provider transmittal](https://health.maryland.gov/mmcp/provider/Documents/transmittals/PT94-26_MPRIME_Updates_June2026.pdf) * Billing before approval Providers will be unable to bill or be paid for claims before their enrollment application is approved. [Maryland Medicaid, June 2026 provider transmittal](https://health.maryland.gov/mmcp/provider/Documents/transmittals/PT94-26_MPRIME_Updates_June2026.pdf) * What we see in practice 45 to 90 days from submission to an active Medicaid ID. ## In the official words > Revalidation is required every 5 years for all Maryland Medicaid providers to remain enrolled and in good standing. [Maryland Department of Health](https://health.maryland.gov/mmcp/provider/Documents/Maryland-Medicaid-Provider-Enrollment-FAQ.pdf) > …all providers are required to submit all claims within 12 months of the date of service [Maryland Department of Health](https://health.maryland.gov/mmcp/provider/Documents/transmittals/PT94-26_MPRIME_Updates_June2026.pdf) ## A backdated start date is available through December 31, 2026 A provider that was not enrolled in time can still get a backdated start date. The application hold was a period when the department returned new or updated applications without processing them, and a complete and processable application filed on or before December 31, 2026 can reach back to the start of that hold. [Maryland Medicaid, June 2026 provider transmittal](https://health.maryland.gov/mmcp/provider/Documents/transmittals/PT94-26_MPRIME_Updates_June2026.pdf) [Maryland Medicaid, MPRIME page](https://health.maryland.gov/mmcp/provider/Pages/mprime.aspx) The backdate is the later of two dates: the start of the hold for the provider type, which was July 1 for moderate and high risk types and August 1 for limited risk types, or the provider’s license issuance date. Once the application is approved and the backdate granted, claims for services in the backdate period are submitted, still within 12 months of the date of service. [Maryland Medicaid, June 2026 provider transmittal](https://health.maryland.gov/mmcp/provider/Documents/transmittals/PT94-26_MPRIME_Updates_June2026.pdf) Backdates are not assured. An incomplete or incorrect application is returned for corrections, a provider that misses the December 31 deadline gets its effective date under standard processes, and providers who render services without enrolling do so at risk. [Maryland Medicaid, June 2026 provider transmittal](https://health.maryland.gov/mmcp/provider/Documents/transmittals/PT94-26_MPRIME_Updates_June2026.pdf) The department’s October 2026 FAQ says [MPRIME](https://health.maryland.gov/mmcp/provider/Pages/enrollment.aspx) replaces its predecessor on October 13, 2026. It says information on file will be transferred to [MPRIME](https://health.maryland.gov/mmcp/provider/Pages/enrollment.aspx), each user will need to create a new user account and associate it with their providers, and documents and attachments from the earlier document library will not be loaded. [Maryland Medicaid Provider Enrollment FAQ](https://health.maryland.gov/mmcp/provider/Documents/Maryland-Medicaid-Provider-Enrollment-FAQ.pdf) ## How enrollment works, step by step 1. Confirm your business registration. Every provider billing Maryland Medicaid needs the appropriate State Department of Assessments and Taxation number and has to keep it in good standing, and an application cannot be continued if the business is not in good standing. [Maryland Medicaid Provider Enrollment FAQ](https://health.maryland.gov/mmcp/provider/Documents/Maryland-Medicaid-Provider-Enrollment-FAQ.pdf) 2. Enroll under your legal name. Providers must be enrolled with the legal name on file with the IRS, and for groups and facilities the name on the IRS letter must match the legal business name on the application. [Maryland Medicaid Provider Enrollment FAQ](https://health.maryland.gov/mmcp/provider/Documents/Maryland-Medicaid-Provider-Enrollment-FAQ.pdf) 3. Enroll each location separately, each with its own NPI, and do not consolidate locations under one account. Most hospitals and providers with an individual Type 1 NPI are excluded from the unique NPI requirement. [Maryland Medicaid Provider Enrollment FAQ](https://health.maryland.gov/mmcp/provider/Documents/Maryland-Medicaid-Provider-Enrollment-FAQ.pdf) 4. File the application in [MPRIME](https://health.maryland.gov/mmcp/provider/Pages/enrollment.aspx) with the documents your provider type needs. The department publishes a lookup of the files, forms and credentials required, which you can filter by provider type and practice style. [Maryland Medicaid, enrollment requirements](https://health.maryland.gov/mmcp/provider/Pages/enrollment-requirements.aspx) 5. A deficient application comes back for corrections, and nothing can be billed or paid until the application is approved. [Maryland Medicaid, June 2026 provider transmittal](https://health.maryland.gov/mmcp/provider/Documents/transmittals/PT94-26_MPRIME_Updates_June2026.pdf) The steps above show where a Maryland file can be stopped: a business registration that is not in good standing, a legal name that does not match the IRS letter, or a location that is missing its own NPI. A deficient application comes back for corrections and nothing can be billed until it is approved, so our figure for a Maryland file is 45 to 90 days from submission to an active Medicaid ID. ## Revalidation every five years Put each provider’s revalidation date on the calendar now, because a missed cycle puts enrollment and good standing at risk. [Maryland Medicaid Provider Enrollment FAQ](https://health.maryland.gov/mmcp/provider/Documents/Maryland-Medicaid-Provider-Enrollment-FAQ.pdf) When a provider is due, account administrators receive an email notification, a notification inside [MPRIME](https://health.maryland.gov/mmcp/provider/Pages/enrollment.aspx) and a revalidation letter, at 90, 60 and 30 days from the due date. The next revalidation date is shown on the Provider Home page in [MPRIME](https://health.maryland.gov/mmcp/provider/Pages/enrollment.aspx). [Maryland Medicaid Provider Enrollment FAQ](https://health.maryland.gov/mmcp/provider/Documents/Maryland-Medicaid-Provider-Enrollment-FAQ.pdf) Providers have 90 days from the due date to complete the application. If it is not completed by then, the account is suspended, although no gap in enrollment status occurs if the revalidation is completed within one year of the suspension. [Maryland Medicaid Provider Enrollment FAQ](https://health.maryland.gov/mmcp/provider/Documents/Maryland-Medicaid-Provider-Enrollment-FAQ.pdf) ## Where Maryland enrollments lose money Two clocks run at once: the 12 month filing limit on every claim, and the 90 day revalidation window after which the account is suspended. [Maryland Medicaid, June 2026 provider transmittal](https://health.maryland.gov/mmcp/provider/Documents/transmittals/PT94-26_MPRIME_Updates_June2026.pdf) [Maryland Medicaid Provider Enrollment FAQ](https://health.maryland.gov/mmcp/provider/Documents/Maryland-Medicaid-Provider-Enrollment-FAQ.pdf) Disenrollment is final the moment it is filed. Payments stop immediately from the date the disenrollment application is submitted, it cannot be undone, and a provider disenrolled in error has to submit a new application with a new effective date. [Maryland Medicaid Provider Enrollment FAQ](https://health.maryland.gov/mmcp/provider/Documents/Maryland-Medicaid-Provider-Enrollment-FAQ.pdf) Control who holds administrator access. Any user with the validating information can become an administrator of an account without the provider granting access, and administrators can make all provider related changes, including application submission and disenrollment.
