I have an HSA with Fidelity. We've been paying all medical expenses out of pocket for the last five years but we are making a large purchase this year and rather than taking the extra needed funds from our Roths I'd like to first take what I can from the HSA since it's less versatile. I have the saved receipts for each year's medical expenses.Is it best to draw out the money in a series of hunks that match each year's expenses or is it acceptable to make one withdrawal for the total of the five year's worth of expenses? I'm not wanting to stir up any undue attention that might initiate an audit. I'm also a little unclear how I get the cash. Do I just go to a bank and use as a debit card to withdraw?
