Can a pharmacy transfer "on hold" CDS prescriptions?
The Drug Enforcement Administration (DEA) has issued a statement allowing pharmacies to transfer “on-hold” Schedule II-V electronic prescriptions from one pharmacy to another if they had not been filled at the original pharmacy. However, they require the transfer to be done electronically and the EPCS software does not permit pharmacies to transmit prescriptions from one pharmacy to another. Fax transmittal is not considered to be electronic transmission. If software is changed to accommodate the requirements of EPCS, then “on-hold” CDS prescriptions may be transferred between pharmacies.
Can a pharmacy transfer "on hold" CDS prescriptions?
Yes. If the pharmacy and the prescriber have the appropriately credentialed software then you are able to accept any prescription through that system. However, you cannot transfer a CII prescription to another pharmacy if you are unable to fill it. The doctor will need to re-transmit it to the new pharmacy.
Simple question: electronic transfer of unfilled CII between pharmacies is allowed or not? If both use EPCS.
