Which of the following types of descriptors may be used in Blank D on the ABN form?

The correct answer encompasses both the terms "Item" and "Procedure," which are used to describe what Medicare may not cover under certain circumstances on the Advance Beneficiary Notice of Noncoverage (ABN) form. When filling out Blank D on the ABN, the provider must specify the particular service or procedure that may not be covered by Medicare.

Using "Item" refers to a specific product or piece of equipment that a patient may receive, which could be denied coverage if it does not meet Medicare's criteria. On the other hand, a "Procedure" refers to a specific medical treatment or service provided to a patient.

The inclusion of both descriptors allows for greater clarity for the patient regarding the nature of the service or item they might receive and the potential for non-coverage by Medicare. This understanding is crucial for patients to make informed decisions regarding their healthcare and any financial responsibilities they may incur.
