What is not a function of the revenue cycle?

The correct answer is physical therapy, as it does not pertain to the revenue cycle functions. The revenue cycle consists of processes that ensure the financial health of a healthcare organization by managing the flow of revenue, starting from patient registration and insurance verification to billing and collection.

Credentialing involves verifying the qualifications, experience, and other credentials of healthcare providers. This is an important part of ensuring that only qualified providers offer services, affecting the organization's ability to bill for those services.

Charge posting is the process of recording services rendered to patients in the billing system. This is critical for accurate revenue capture.

Claims processing involves the filing and handling of claims submitted to insurance companies for reimbursement. This function is essential to ensure that the billed services are appropriately reimbursed.

In contrast, physical therapy relates directly to patient care and treatment rather than the financial processes of the organization. It does not directly contribute to the revenue management aspects that are central to the revenue cycle.
