Implementation of Ordering/Referring Professional Enrollment Requirement
As required by the Affordable Care Act, New York Medicaid has initiated claims editing requiring Medicaid fee for service enrollment for ordering/prescribing/referring/attending (OPRA) physicians and other healthcare professionals. Effective for dates of service January 1, 2014 and forward, if the OPRA professional is not enrolled, eMedNY will PEND affected claims for up to four payment cycles. Rather than deny the claim initially, the pending of these claims will provide an opportunity for OPRA enrollment applications to be processed, allowing these claims from billing providers to be paid.
