Final answer:
Modifier 32 is appropriate for Evaluation and Management services when they are rendered at the request of another physician or appropriate source, such as for second opinions or consultations.
Step-by-step explanation:
To appropriately add the modifier 32 to an Evaluation and Management service, there are certain criteria that need to be met. Modifier 32 is used when the service is rendered at the request of another physician or appropriate source. It is typically used for second opinions or consultations.
For example, if a patient sees their primary care physician and the physician believes a specialist's opinion is necessary, they may request a consultation from the specialist. In this case, the specialist would use modifier 32 when billing for the service.
It is important to note that modifier 32 should not be used solely for obtaining payer authorization or to meet insurance requirements. It should only be used when the specific criteria for modifier 32 are met.
