I went to Gemini, Google's A.I. and received the following to my financial question. I am sharing Gemini response below.

"Here is the breakdown of your maximum potential out-of-pocket costs with your UnitedHealthcare AARP Part D plan for 2025:
List Price: Brinsupri has an annual list price of approximately $88,000.
Initial Costs: Depending on your specific plan's deductible and coinsurance rate (which could be around 31% for a specialty tier drug), you would pay a portion of the initial cost. The calculation of 31% of $88,000 is indeed around $27,280, but this amount is limited by the annual cap.
The Out-of-Pocket Cap: The Inflation Reduction Act eliminated the 5% coinsurance requirement in the catastrophic coverage phase and placed a hard cap on annual out-of-pocket spending.
Your Maximum Annual Cost: In 2025, the maximum amount you will pay out of pocket for all your covered Part D prescription drugs is $2,000. Once you have paid this amount, your plan covers the full cost of the medication for the rest of the year.
Therefore, your total annual cost for Brinsupri, without any additional financial aid programs, would be a maximum of $2,000, assuming you have no other prescription costs that count towards this limit. The cap for 2026 will be $2,100.
You can also explore patient support programs offered by Insmed, the manufacturer, which may help with initial costs or deductibles. You can find more information about your specific plan's benefits, prior authorization requirements, and network specialty pharmacies by contacting UnitedHealthcare directly via their AARP Medicare Plans website or by calling the number on your member ID card.
