请教老猫及各位大佬 about health saving account

I left company on Jan 15 and I personally put about $120 in to my health saveing account on Jan 8(just one paycheck), I planned to put $2000 for whole year. on Jan 8, my company also put $2000 into my account. I had about $1600 medical expense on Jan 10, do I have right to get reimbursed by my health saving account?  My understanding is all my benefit including medical insurance and medical saving account should be good for me to use until Jan 31.  Am I right?

Thanks for your help.
