What system allows the resolution of prescription coverage through communication between the pharmacy computer and the third-party computer?

The online adjudication system is crucial in the process of prescription coverage because it facilitates real-time communication between a pharmacy's computer system and the third-party payer's system. This immediate interaction allows for the verification of a patient's insurance benefits, coverage limits, and any applicable copays or prior authorizations at the point of sale. By enabling pharmacists to receive instant feedback about the claim's approval or denial, the online adjudication system streamlines the dispensing process, reduces patient wait times, and improves overall efficiency in pharmacy operations.

In contrast, other systems serve different purposes; for instance, a claim adjustment system is typically used for correcting claims after they have been submitted, while a pharmacy benefit management system oversees the management of pharmacy benefits and might handle broader aspects of patient claims but not in real-time. A prescription verification system focuses more on ensuring that the correct medication is dispensed rather than handling insurance claims.
