-mfx- is giving you extra information for the model you just ran. 

The help for -xtnbreg postestimation- indicate how to get predictions in Stata. There is no need to resort to any other software.

I have a count panel data model with interaction terms where the terms
are mean centered.  

I estimated the full model by -xtnbreg- and ran -mfx-.  The marginal effect
table presents the same coefficients and standard errors as the table for
-xtnbreg-. Is this possible?

If I do get the correct -mfx- output, how do I compute predicted Y? Do I have
compute y = exp(XB) where B stores marginal effects separately in Excel ?
