<prompt> Human: Earlier this year I had about 5000 in medical expenses that I paid for out of pocket. I currently have 2000 in my HSA.1. Can I reimburse myself in two steps for the same expense? Meaning 2000 now, 3000 next year when its built up2. Is there a time limit as to when I can reimburse myself?  <response>: The only time limit is that your HSA must have existed when the medical expense was incurred. Counting rollovers.
