What kind of diagnosis/symptom code is 304.8?

Question

and if i request a drug screen and this is the code what does it mean?

Answer 1

It cannot be used for a diagnosis as it is non-specific, but it means drug dependence not including opioids. So if you were requesting a drug screen, this means that you are screening for other drugs besides opioids (cocaine, marijuana, etc.), not heroin/morphine.
