When providing screening mammograms for Medicare patients, an organization may need to issue an ABN if:

The correct choice focuses on the situation where the patient has already received a screening mammogram within the past 12 months. In this scenario, Medicare guidelines state that routine screening mammograms are typically covered once every 12 months for women aged 40 and older. If a patient attempts to receive another screening mammogram within this timeframe, the healthcare provider must issue an Advance Beneficiary Notice (ABN) to inform the patient that Medicare may not cover the cost of the additional service. This ensures that patients are aware of potential out-of-pocket expenses before the service is rendered.

Issuing an ABN in this circumstance helps protect the organization from financial liability and provides transparency to the patient regarding their care options and the potential for denied coverage. This situation aligns with Medicare's policies regarding preventive services and their frequency limits, making it essential for providers to stay compliant while maintaining patient communication.

Other scenarios, such as the patient's history of breast cancer, requests for additional services, or being a new beneficiary, do not automatically necessitate an ABN according to Medicare guidelines. An established frequency limit applies specifically to the timing of the screening mammogram, which clearly demonstrates when an ABN is required.
