Final answer:
The supplier has 60 days to fill the remainder of a partially fulfilled hydromorphone order according to DEA regulations.
Step-by-step explanation:
When a supplier receives an order for hydromorphone, a controlled substance, and they do not have enough supply to complete the order, they are given a specific timeframe to fill the remainder of the order. According to DEA regulations, the supplier has 60 days to provide the balance of the order.
This means that if the supplier sends a partial shipment, they must complete the shipment, delivering the rest of the hydromorphone ordered, within 60 days from the date the initial partial shipment was sent. Failing to complete the delivery within this period may require a new order to be issued by the purchaser.
