Not enough money in my HSA account to get reimbursed for this year's medical expenses.

This year my total medical expenses came out to about $5000. All paid with my debit card. I only have $700 in my HSA account currently and wanted to reimburse myself. What is the best way to get the best Tax deduction in this case? Should I:

- Contribute $4300 to my HSA and then reimburse myself for $5000?

- Reimburse myself for $700?

- Don't do anything and try itemize all medical expenses on my tax return (I realize I can only deduct medical expenses that exceeds 10% of my AGI but I am not sure what my AGI will be this year).

- Any other suggestion?


Thanks!
