Abnormal urine levels of substances chiefly nonmed source

This code signifies the presence of unusual or elevated levels of non-drug substances in a patient's urine. These substances are typically exogenous and not related to prescribed medications or common metabolic byproducts. It indicates an abnormal finding on urinalysis that requires further investigation into potential environmental exposures or ingestion.

This code is appropriate when laboratory results from a urinalysis reveal the presence of substances not typically found in urine, and these substances are not medicinal in nature. Documentation should clearly state the specific non-medicinal substance identified (e.g., heavy metals, industrial chemicals, recreational drugs not classified as medicinal). This code is often used when screening for environmental toxins or substance abuse.

• Do not use this code for abnormal levels of endogenous substances (e.g., glucose, protein, ketones) or prescribed medications.
• Always seek documentation of the specific non-medicinal substance identified in the urine.
• Consider sequencing this code after a more definitive diagnosis if the abnormal finding leads to a specific condition (e.g., toxic effect of substance).
