Abn lev drug/meds/biol subst in specimens from resp org/thrx

Abnormal level of other drugs, medicaments and biological substances in specimens from respiratory organs and thorax

📋Clinical Description

This code indicates the presence of an abnormal concentration of non-endogenous substances, such as medications, illicit drugs, or other chemicals, detected in a specimen collected from the respiratory system or thoracic cavity. This finding suggests potential exposure, overdose, or therapeutic monitoring issues related to these substances.

🎯When to Use

Apply this code when laboratory results from respiratory specimens (e.g., sputum, bronchoalveolar lavage, pleural fluid) or thoracic tissue biopsies reveal an abnormal level of drugs, medicaments, or other biological substances. Documentation must clearly state the abnormal finding and the specific substance(s) identified.

💡Coding Tips

Do not use for abnormal levels of endogenous substances (e.g., electrolytes, hormones).
Requires specific documentation of the substance and the respiratory/thoracic source of the specimen.
Consider sequencing with codes for the underlying condition or reason for testing, if applicable.
