Elevated urine levels of drug/meds/biol subst

This code indicates the presence of abnormally high concentrations of pharmaceutical agents, therapeutic compounds, or naturally occurring biological substances in a patient's urine. It signifies a laboratory finding rather than a specific disease, often pointing to recent ingestion, impaired metabolism, or overdose.

This code is appropriate when laboratory results confirm elevated levels of drugs (e.g., illicit drugs, prescribed medications), medicaments (e.g., over-the-counter substances), or biological substances (e.g., hormones, metabolites) in a urine sample. Documentation should clearly state the specific substance(s) found and the elevated concentration.

• Always code the specific substance(s) identified in the urine using codes from categories T36-T50 (Poisoning by, adverse effect of and underdosing of drugs, medicaments and biological substances) as primary or secondary diagnoses, if known.
• This code should generally be sequenced after the definitive diagnosis for the condition causing the elevated levels (e.g., drug overdose, substance abuse, metabolic disorder) or the reason for the urine test.
• Do not use this code for normal or expected levels of substances in urine, or for substances that are merely present without being elevated.
