Summary
Effective August 4, 2008, pharmacies must use National Provider Identifier (NPI) numbers when billing for over-the-counter Plan B emergency contraception. For OTC Plan B claims, pharmacies must use the specific NPI '2223334444' in the Prescriber ID field along with 'PLANB' as the prescriber last name.
Action Required
This is a historical policy from 2008 that only affects pharmacies billing for over-the-counter Plan B emergency contraception. Medical practices do not need to take any action as this policy applies specifically to pharmacy billing procedures, not physician billing.
