Final answer:
The precise deductible amount for Medicare Part A beneficiaries per Benefit Period is not provided in the text. For accurate numbers, official Medicare resources should be referenced as deductibles can vary yearly.
Step-by-step explanation:
Medicare Part A beneficiaries have a per Benefit Period deductible which is not explicitly stated in the provided information. However, it is important to note that Medicare Part A is known to have a deductible, and enrollees are responsible for this payment before Medicare payments are authorized. For the most current and accurate deductible amounts, one should consult the official Medicare resources or recent updates to the program since these figures can change annually.
