Introduce Amivantamab in Periph Vein, Perc, New Tech 7

This code describes the administration of amivantamab, a monoclonal antibody, directly into a peripheral vein. This procedure is performed percutaneously, meaning through the skin, without an open incision, and utilizes a novel technology.

This code is appropriate for inpatient encounters where amivantamab is infused intravenously for the treatment of advanced non-small cell lung cancer (NSCLC) with EGFR exon 20 insertion mutations. It specifically applies when the drug is delivered via a peripheral intravenous line.

• Ensure documentation clearly specifies amivantamab as the substance introduced.
• Verify the approach is percutaneous and the administration route is a peripheral vein.
• Confirm the inpatient setting for appropriate ICD-10-PCS code assignment.
