Answer: She should file an appeal of this initial determination within 120 days of the date that she got the Medicare Summary Notice in the mail
Step-by-step explanation:
The Medicare Summary Notice refers to the notice that the individuals who have Original Medicare get in their mail for Medicare Part A and Part B-covered services.
Since Mrs Duarte disagrees with a determination that partially denied one of her claims for services, then she should file an appeal of the initial determination within 120 days of the date that she got the Medicare Summary Notice in the mail.
