I have an HSA account that has grown sufficiently that I've been offered the option to invest the funds in one or more money market funds offered by the fund mgmt company. I'll be turning 65 in a few years. I'm reading that once you become eligible for Medicare you can no longer contribute to the HSA. My question is, what about the dividends being earned in the money market fund? Are these dividends considered contributions? Do I have to remove the funds from the money market fund so that the HSA no longer grows? I know I don't have to remove the money from the HSA, just asking if it's allowed for the funds to grow from the dividends after I turn 65.

Update: Thanks to all for your responses. One less thing to worry about in my old age 😄.
