I'm assuming that you are asking about the Box-14 from your W2?
The Box 14 of your W-2 is used to report information that doesn't belong to any other category. Usually this box is for informational purposes only. The USA-HOUSI sometimes refers to Clergy Housing Allowance. You can also verify with your employer or the payroll department of your company for a more accurate response.
