A _____ number is assigned by CVS to identify each Third Party Plan?

The correct answer is "Plan Code." A Plan Code is specifically designated by CVS to identify each Third Party Plan. This unique identifier helps in streamlining the processing of claims and managing the relationships with different insurance providers. Using a Plan Code ensures that the pharmacy can accurately bill the correct third-party payer, making it an essential part of the pharmacy's operational workflow.

Other options, such as Authorization Code, Condor Code, and Reference Code, serve different purposes within the pharmacy or healthcare setting. Authorization Codes are typically used for obtaining pre-approval for certain medications or services. Condor Code is not a widely recognized term in this context, and its use may vary by specific internal systems. Reference Codes may be used for various tracking or referencing needs rather than specifically identifying a third-party plan. Thus, Plan Code is the most relevant and precise choice for identifying Third Party Plans in the context of CVS operations.
