What information must be provided to the payer upon receipt of direct payment?

The requirement to provide certain information to the payer upon receiving direct payment is essential for ensuring transparency and proper documentation in the billing process. The correct option highlights three key components that must be communicated: the amount charged, the procedure or diagnosis codes, and a notation of the services rendered.

The amount indicates the total charge for the provided services, which is critical for the payer’s records and for reconciling accounts. Procedure and diagnosis codes are essential for categorizing the services performed and ensuring that billing aligns with medical coding standards. Finally, a notation of the services offers a brief description of what was actually performed, which aids in clarifying the context of the billed amount and codes.

In contrast, the other options do not encompass the specific and necessary information needed for processing payments effectively. Patient's insurance details and treatment plans are more relevant for initial insurance processing rather than direct payment contexts. Provider qualifications and referral sources do not pertain to payment receipt information. Billing guidelines and patient rights also fall outside the scope of direct payment requirements since they focus more on procedural regulations than on what needs to be documented at the point of payment receipt.
