In which method are services billed individually rather than in a consolidated manner?

The method where services are billed individually rather than in a consolidated manner is referred to as Separate Reimbursement. This approach allows providers to itemize and charge for each specific service or procedure rendered. Each charge reflects the actual cost associated with that particular service, enabling clearer tracking of expenses and more detailed billing for patients and insurers.

In contrast, bundled reimbursement encompasses multiple services or procedures that are grouped together and billed as a single charge. This can simplify billing processes but does not highlight individual service costs. The Inventory Model pertains to managing stocks of medications or supplies rather than the billing process. Orphan Drugs are medications developed specifically for rare diseases and typically have unique pricing or reimbursement considerations but do not involve separate billing methods. Therefore, Separate Reimbursement is the correct choice, as it directly aligns with the practice of billing services individually.
