Pathology and Laboratory: Chemistry (Q & A) (March 2011)
March 2011 page 10b Pathology and Laboratory: Chemistry Question: What is the correct code to report for quantitative drug assays that are performed by chromatography and not defined in codes 80150 - 80202 ? Should these assays be reported with code 80299 or code 82491 ? Answer: Quantitative chromatography for analytes should be reported with the drug-specific code specified in either the Therapeutic Drug Assay or Chemistry subsections, if available. If the drug specific code does not exist, it is appropriate to assign the applicable chromatographic methodologic code to describe this service (e.g., 82491 , Chromatography, quantitative, column (eg, gas liquid...

Article Overview
This March 2011 CPT Assistant chemistry Q&A focuses on how to classify certain laboratory drug assays within the CPT framework. It is relevant to laboratory coders, pathology practices, and compliance staff who need to understand which broad CPT chemistry or therapeutic drug assay categories may apply when a specific assay is or is not named. The article discusses the general relationship between drug-specific reporting, chromatographic methodology, and unspecified drug quantitation in a way that helps readers assess whether the full guidance is relevant to their workflow.
Why This Topic Matters
Correct laboratory reporting depends on matching the service to the appropriate CPT category, especially when a test is method-based or when a named assay is not available. This article helps coders and billing teams understand the scope of the guidance before consulting the full premium text.
