The MAGI for Medicaid is $16,242. My income was $22,568.46. Can I contribute to a Traditional IRA to reduce my income to meet the medicaid MAGI requirement?

I'm not totally sure how the MAGI is calculated.  For Example I have dividends (1099-DIV) that have created a cash balance of $918.82 over the last 2 years (not just 2016), and I don't know if that's included as income for the MAGI.

Here is the breakdown of the sources of my income:

I realize that the contribution limit for an traditional IRA is $5,500.  I guess I'm hoping some of this income doesn't count toward the MAGI.  Please help!
