Answer:
I would advise Mr. Schultz to enroll in a Part D plan as soon as possible in order to avoid the late enrollment penalty.
He can enroll in a plan online, by phone, or in person. I would also advise him to compare different plans to ensure he selects the one that best meets his needs.
Additionally, he should review his plan's coverage and premiums, and make sure that it covers any medications he takes.
Finally, I would suggest he check if he qualifies for any low-income assistance programs or other forms of financial help to reduce his drug costs.
