We are having trouble finding a specific ICD-10 for drug screening by urine. There are no signs or symptoms, the patient has to be drug tested periodically for a legal diversion program. Any help would be appreciated.
If the patient has a diagnosed substance abuse disorder and is being treated for that, you could code for the abuse, dependence etc. Otherwise this is an exam for medicolegal reasons (ie court mandated/ordered treatment) which would fall under Z04.8 Encounter for examination and observation for other specified reasons
