What is the testing code used when a physician orders a urinalysis test due to observed medical signs of drug abuse?

The testing code used when a physician orders a urinalysis test due to observed medical signs of drug abuse is designated as Medical Examination (MO). This code is appropriate because it reflects a scenario where a medical professional has identified symptoms or signs that warrant further investigation, specifically through urinalysis. The physician’s orders are based on clinical observations, focusing on the health and welfare of the individual.

Choosing this code ensures that the testing is conducted in a context where there is a legitimate medical concern, contrasting with other testing types that may not relate to immediate health assessments. For instance, Random Testing would be done without specific symptoms prompting it, Pre-Employment Screening is designed to evaluate prospective employees before hiring, and Behavioral Assessment would relate more to observations of behavior rather than direct medical evaluation. Thus, the Medical Examination (MO) code is the most appropriate in this context.
