Non-ABD Med-Quest and income from stock sales

I am way up on a stock, and I am itching to sell it. I want to use the money to help pay off the principal of my mortgage. It would put me over the monthly income limit, but not the yearly.

I have already been approved this year until early 2027. I am required to report any income changes within 10 days though.

Considering I have been approved for the year I am not sure if it will affect me this year at all, but before I sell it all I want to make sure.

What makes this tougher is I have some medical procedures coming up next month, so losing it for next month would not be good for me.

I've tried calling Med-QUEST, but the person I was speaking to was obviously confused. She said that in my case being non-ABD and under 65 it wouldn't matter. I think she was confusing the asset limit for the income limit, or was she? I even clarified that I meant income and not assets. I went so far as to spell it out and explain I would be selling it and depositing it into my bank account. She still said it wouldn't affect my eligibility.

What is the truth? This sounds too good to be true.
