A Primer on Assignment of Payment
Many Medicare practitioners, providers, and suppliers do not directly bill for the services they supply and similarly do not directly receive reimbursement. Billing and reimbursement may occur through an employment or independent contractor relationship, through a billing company, or through another arrangement. However, each of these arrangements must comply with the Medicare assignment of payment rules that dictate how and to whom the practitioner, provider, or supplier may assign their right to receive reimbursement from Medicare.
The general rule is that Medicare will pay assigned benefits only to the physician, practitioner, or supplier who furnished the service, and not to another person or entity. To reassign payment to another person or entity, an arrangement must meet one of several enumerated exceptions. The most common exceptions are:
Payment to Agent: Medicare may make payment, in the name of the provider, to an agent who furnishes billing or collection services. In general, the agent or billing company may not have a financial interest in the dollar amount billed or the actual collection of payment, and the agent must act under payment disposition instructions which the provider may modify or revoke at any time. Different provisions may apply if the agent merely prepares bills and does not receive payment for the provider or supplier.
