What is the CPT code for a digoxin assay?

The CPT code for a digoxin assay is 80162. This code specifically pertains to the quantitative measurement of digoxin levels in the blood, which is crucial for monitoring drug levels in patients who are undergoing treatment for various heart conditions, such as atrial fibrillation or heart failure. Monitoring these levels is essential because digoxin has a narrow therapeutic index, meaning that the difference between an effective dose and a toxic dose is small.

The use of this code indicates that the laboratory service performed is tailored to digoxin, allowing healthcare providers to manage dosage effectively and mitigate potential toxicity. This specificity is essential for coding purposes in order to ensure proper billing and reimbursement for laboratory services.

The other codes listed pertain to different assays or substances and are not applicable to the digoxin assay. Each code in the 80000 series typically corresponds to a particular test or panel, and selecting the correct code is vital for accurate medical coding and billing practices.
