Separate coding for drug test components (e.g., collection, analysis) when a single code for the complete test exists. Leads to overbilling.
Using unspecified drug test codes when more specific documentation supports a particular drug class. Reduces claim accuracy.
Lack of documented medical reason for the urine drug test. Causes claim denials and compliance issues.
Urine drug screen (UDS) ordered to evaluate for substance use, monitor prescribed medications, assess for potential overdose, or as part of a pain management agreement. Patient presentation may include symptoms such as altered mental status, withdrawal symptoms, or behavioral changes. Reasons for testing include pre-employment screening, reasonable suspicion, post-accident testing, or routine monitoring. The UDS panel includes amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine metabolites, methadone, opiates, phencyclidine, and tricyclic antidepressants. Results are reported as positive or negative for each substance, with quantitative levels where applicable. Positive results were correlated with clinical findings and patient history. Differential diagnosis includes medication non-compliance, exposure to environmental toxins, or false-positive results due to cross-reactivity. Plan includes counseling regarding substance use, medication management, referral to addiction treatment services, and further investigation if clinically indicated. ICD-10 coding will be based on specific substances identified and clinical indications (e.g., F11.10 Opioid dependence, uncomplicated; F14.181 Cannabis dependence with withdrawal; T40.4X1A Adverse effect of cocaine). CPT codes for the UDS will be chosen based on the complexity of the panel performed (e.g., 80100, 80101, 80102). This documentation supports medical necessity for the UDS and guides subsequent treatment decisions.
