Greetings my Fellow Coders!

I'm in need of accurate assistance regarding facility ER coding for an IV Push. If the documentation is missing the "stop time" for an IV push, is it "ok" to still code this procedure?

In addition, does anyone know of a website that I can refer to regarding policies on this matter. Does anyone also know of a website that provides information on drugs that are commonly used for an IV Push and drugs that are commonly used for an IV Infusion? Any assistance is truly appreciated!
