Summary
Maryland Medicaid has established a new email address (mdh.adjustmentunit@maryland.gov) for adjustment inquiries on claims older than 90 days, effective October 1, 2025. Additionally, providers can now submit Medicare Part A claims electronically through eMedicaid instead of being required to submit them on paper.
Action Required
By October 1, 2025: Update billing team procedures to use new email mdh.adjustmentunit@maryland.gov for Medicaid adjustment inquiries on claims past 90 days (must include provider contact info, date of service, recipient ID, and provider ID). Train staff on new eMedicaid Part A claim submission functionality accessible via 'eClaim (UB04 Part A)' link. Update billing workflows to utilize electronic submission option for Medicare Part A claims that don't crossover successfully.
