What additional information is often necessary in Block 17 when indicated?

In Block 17 of the CMS-1500 form, which pertains to the referring physician when applicable, it's important to include the supervising physician's name if the patient was referred to the provider for treatment. This additional detail helps in tracking the patient's care pathway, ensuring that all healthcare providers involved in the patient's treatment are appropriately documented.

Including the supervisor physician’s name aids in coordination of care and allows insurance companies to recognize the relationship between the referring provider and the provider performing the service. It ensures that the claim can be processed accurately, especially when special considerations or approvals are required due to the nature of the patient's referral.

While the other options may contain relevant information in other healthcare contexts, they do not specifically align with the requirements or purpose of Block 17 on the CMS-1500 form, which is focused on documenting the referring or supervising physician's information when applicable.
