Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 96446 covers

This service covers delivery of antineoplastic medication into the peritoneal cavity through an indwelling port or catheter. It is commonly performed by oncology clinicians for patients receiving intraperitoneal treatment, including treatment for ovarian or other cancers involving the peritoneum. The access device is already in place; this code describes the chemotherapy administration, not placement of the port or catheter. It is distinct from delivering medication into the pleural cavity, central nervous system, or bloodstream.

Select the code based on the medication’s route and the access method, not simply the drug used or the patient’s diagnosis. Documentation should identify the antineoplastic agent, the intraperitoneal route, use of the indwelling access device, and the administration performed. The medication product is separate from the administration service and may be reported with its applicable drug code when separately furnished and reportable. It is billed as an incident-to service only when performed under physician supervision.
