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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

96446 billing questions

When should 96446 be selected instead of 96440?

Use 96446 for chemotherapy delivered into the peritoneal cavity through an indwelling port or catheter. Code 96440 is for delivery into the pleural cavity.

Does 96446 include placement of the port or catheter?

No. The service is administration through an indwelling device; placement is not described by this code.

Is the chemotherapy drug included in 96446?

The code represents the administration service, not the drug product. Report the applicable drug code separately when the product is separately furnished and reportable.

What documentation supports reporting 96446?

Document the antineoplastic medication, intraperitoneal route, indwelling port or catheter used, and the administration performed.

What supervision condition applies to Medicare billing?

CMS identifies this as an incident-to service: it is billed only when performed under physician supervision.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
