SAS Logistic Regression - High Wald Chi square for a binary variable

I am working on an analytical task where I need to identify why a particular binary independent variable is having high Wald chi-square (approx. 10k) when compared to the other variables (approx in 100's) in the logistic regression model.

Can I simply conclude by saying that the response variable is strongly dependent on that particular binary variable by doing some cross tab or chi-square test of independence or is there any other better way i could explain this stuff to few statisticians here?

Thanks for your help!
