Code for post nasal drip due to cold

Good evening,

I am trying to find a code for post nasal drip due to a patient having a cold and it does not seem to be a chronic condition. When I look up post nasal drip in index it points me to 784.91 but the index states (chronic) besides it. Then it has an entry below that for drip due to common cold: 460. I am unclear which one to code in this case and would appreciate any advice.

Thank you so much!

Noelle
