Chemotherapy administration
About 96405: Intralesional chemotherapy for up to seven lesions
Report 96405 when an antineoplastic drug is administered directly into one to seven lesions, such as in a dermatology or oncology setting.
A physician or other qualified practitioner reports 96405 for administering chemotherapy directly into one or more lesions, with the code covering up to seven lesions. This is a local injection into the lesions, rather than systemic chemotherapy given subcutaneously, intramuscularly, or intravenously. Dermatology and oncology practices commonly provide this service for selected cutaneous lesions; the code represents the administration, not the drug product.
Document the antineoplastic agent, intralesional route, treated sites, and lesion count. Use the code for one through seven lesions; when more than seven are treated, compare the service with 96406. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. CMS does not pay an assistant at surgery for this service, and co-surgeon and team-surgery billing are not permitted.

96405 billing questions
How many lesions can be reported with 96405?
96405 covers administration into one through seven lesions. For treatment of more than seven lesions, compare the service with 96406 rather than reporting 96405 for every lesion.
How is 96405 different from 11900?
96405 is for intralesional chemotherapy. Code 11900 is for intralesional injection of a substance other than chemotherapy, for up to seven lesions.
Is the chemotherapy drug included in 96405?
No. The code represents administration; report a separately payable drug product under its applicable code when the practice supplies it and documentation supports separate reporting.
Should modifier 50 be used when lesions are on both sides?
No. CMS identifies bilateral adjustment as inappropriate for 96405. Report the service based on the number of treated lesions, not as a bilateral procedure.
What documentation supports 96405?
Record the drug, intralesional route, lesion locations, and number of lesions treated. The count supports choosing 96405 for up to seven lesions or 96406 for more than seven.
How does CMS handle other procedures performed in the same session?
The highest-valued procedure is paid in full, and other procedures in the same session are subject to the standard multiple procedure reduction. CMS does not pay an assistant at surgery for 96405.
