Blank w2 form from employer except for box 14

I received an additional W2 from my employer with just the following info on it:

Box (a) is filled out

Bob (b) is filled out

Box (c) is filled out

Box 14 has MED2 with an amount in it

All other boxes are blank. 

Do I need this? 

Can I combined this amount onto my other W-2 to e-file?
