- Claim Dispute: Request for review of a denied or underpaid claim.
- Reconsideration: Request for reconsideration of CareFirst CHPMD’s decision based on new or additional information.
- Resubmission: Request for review of denial or payment amount because of incorrect coding or missing information.
Submit all disputes using the Post Claims Adjudication Payment Dispute Form.
To receive payment for services rendered to Maryland Medicaid recipients, MDH requires all providers to maintain an active enrollment status in ePREP.
ePREP serves as a comprehensive platform for provider enrollment, reenrollment, revalidation, information updates and demographic changes. Maintaining active enrollment minimizes the likelihood of claim denials.
To enroll in ePREP or check the status of prior enrollment, go to the Maryland Dept of Health Provider Enrollment page.
Access the ePREP Quick Reference Guide for more information.
