What system allows resolution of prescription coverage through communication between pharmacy computers and third parties?

The online adjudication system is essential in modern pharmacy operations as it facilitates real-time communication between pharmacy computers and third-party payers, such as insurance companies. When a prescription is presented, the system allows the pharmacy to submit claims and quickly receive updates on whether the prescription is covered under the patient's insurance plan.

This immediate feedback is crucial for pharmacists to inform patients about their coverage options, potential out-of-pocket costs, and alternative medications if coverage is denied. The efficiency of the online adjudication system helps streamline the prescription processing workflow, enhance patient satisfaction, and reduce delays in medication dispensation.

Other systems mentioned serve different purposes. The point of sale system is primarily focused on transactions, handling payment processing at the time of purchase. The perpetual inventory system deals with inventory management, tracking medication stock levels in real-time. A decentralized pharmacy system refers to a model of pharmacy services where medication management is distributed across multiple locations rather than centralized in one facility. These do not specifically address the prescription coverage resolution through communication with third parties as effectively as the online adjudication system does.
