What is the correct code for a polypectomy performed endoscopically when the polyp is malignant with negative margins?

The correct code for an endoscopic polypectomy when the polyp is malignant with negative margins is A280 Polypectomy-Endoscopic. This coding indicates that the procedure was specifically performed using an endoscopic method, which is particularly relevant for polypectomy cases.

In instances where polyps are removed endoscopically, documenting the method helps to provide accurate information regarding the technique used and can affect reporting, billing, and data analysis. The specification that the polyp is malignant but has negative margins is crucial as it indicates that while the polyp is cancerous, the removal was successful in ensuring that no cancerous cells were left behind, which is a key factor in monitoring and treatment outcomes.

The other options lack the specificity required for coding an endoscopic procedure for a malignant polyp. They either categorize the procedure too broadly or are not applicable for the situation described. Proper coding is essential for accurate medical records and can impact patient treatment plans and insurance reimbursements.
