Missing PRSI payments in 2016 while fully employed.

I just got around to getting into the welfare site with MYGOVID.ie.
There are 46 prsi payments in 2016 where there should be 52 as I was in full time PAYE employment.
Is it possible to get my employor to pay these payments respectively at this stage or is it too far in the past?
Thanks in advance for any feedback!

It's not to late. Definitely get your employer to correct this.

Thanks S Class!
