Abnormal level of other drugs, medicaments and biological substances in specimens from other organs, systems and tissues
ICD-10 R89.2 is a billable code used to indicate a diagnosis of abnormal level of other drugs, medicaments and biological substances in specimens from other organs, systems and tissues.
R89.2 is used to classify abnormal levels of drugs, medicaments, and biological substances found in specimens taken from various organs, systems, and tissues. This code is particularly relevant when laboratory tests reveal unexpected concentrations of substances that are not classified under more specific codes. Such findings may indicate potential toxicity, therapeutic failure, or the need for further investigation into the patient's medication regimen. Commonly tested substances include antibiotics, anticoagulants, and other therapeutic agents. The clinical significance of these abnormal levels can vary widely, necessitating a thorough review of the patient's history, current medications, and any recent changes in treatment. Accurate coding requires careful documentation of the laboratory findings, the context of the tests performed, and any associated symptoms or clinical conditions that may be relevant to the abnormal results.
Detailed patient medication history, lab results, and clinical notes explaining the significance of abnormal findings.
Patients presenting with unexplained symptoms where drug levels are tested to rule out toxicity or therapeutic failure.
Consideration of polypharmacy and interactions between multiple medications.
Acute care documentation including immediate lab results, patient presentation, and any interventions performed.
Patients with acute symptoms potentially related to drug toxicity or overdose.
Rapid assessment and documentation are crucial in emergency settings to ensure accurate coding.
Used when drug levels are tested in relation to symptoms.
Documentation of the reason for testing and results.
Internal medicine may require more detailed medication history.
R89.2 should be used when laboratory tests indicate abnormal levels of drugs or biological substances that are not classified under more specific codes, and when these findings are clinically significant.
