The two identifiers associated with a practitioner in the context of Pharmacare are the NPI and DEA number.
Step-by-step explanation:
In the context of Pharmacare, the two identifiers associated with a practitioner are the NPI (National Provider Identifier) and the DEA (Drug Enforcement Administration) number. The NPI is a unique identification number used by healthcare providers, including pharmacists, to identify themselves in electronic transactions. The DEA number, on the other hand, is issued to prescribers and pharmacists who are authorized to handle and dispense controlled substances.
