Summary
Maryland Medical Assistance Program (Medicaid) is launching a new delegated email inbox (mdh.institutionalpru@maryland.gov) for institutional providers to submit claims beyond the 12-month timely filing deadline, appeals, and claims requiring additional review, effective September 1, 2025. Additionally, Provider Services Call Center hours are expanding to 8:30am-4:00pm Monday-Friday for both Institutional and Professional Provider Resolution Units.
Action Required
By September 1, 2025: Billing team must update institutional claims submission procedures for Maryland Medicaid. (1) Add new email address mdh.institutionalpru@maryland.gov to approved submission channels for institutional claims; (2) When submitting claims beyond 12-month timely filing deadline, ensure all attachments include valid timely filing exception documentation and are scanned clearly and legibly before emailing to avoid rejection and resubmission delays; (3) Update call center contact information for Institutional Provider Relations Unit (IPRU) to 410-767-5457 with new hours 8:30am-4:00pm Monday-Friday; (4) Train billing staff on the three eligible request types: claims beyond timely filing deadline with exception documentation, appeals for institutional claims, and institutional claims requiring additional review. Note: Paper mail submission process remains available as alternative. Failure to provide legible attachments will result in returned requests and processing delays.
