Taking a coding class and need help, please.

Hi everyone. I'd really appreciate is someone could help me. In my Next Step Advanced Coding textbook, we are on the Pathology & Laboratory chapter and the case I am stuck on is:

A confirmation of the drug screen is conducted when Martin's tests come back positive for cocaine.

I have the Service Code as : 80102

ICD-10-CM Dx: F14.90

ICD-9-CM Dx: 305.60

Is this correct? Thank you for any help.

Lori
