What 96450 covers

This service covers delivery of chemotherapy into the central nervous system, most commonly by an intrathecal route through a lumbar puncture. It may be performed in an oncology or hematology clinic, hospital outpatient department, or other setting where CNS-directed treatment is administered. Patients may receive it for conditions such as CNS leukemia or leptomeningeal disease. Administration through an intraventricular access device is also a CNS route.

Select this code based on the route of drug delivery, not the drug name or the diagnosis alone. Documentation should identify the medication, CNS route, access method, and completed administration. The spinal puncture used to access the treatment site is included in this service. The chemotherapy drug itself is separate from the administration service when separately reportable. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate. Assistant-at-surgery payment requires medical-necessity documentation; co-surgeons and team surgery are not permitted.

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.

96450 billing questions

When should 96450 be selected instead of another chemotherapy administration code?

Use it when chemotherapy is delivered into the central nervous system, such as intrathecally or through an intraventricular access device. Select other administration codes for different routes, such as subcutaneous, intramuscular, or intravenous delivery.

Is the spinal puncture separately reported with 96450?

The puncture used to gain access for the CNS chemotherapy administration is included in this service.

Does 96450 include the chemotherapy drug?

The code represents the administration service, not the drug product. Report the drug separately when it is separately billable and supported by the claim documentation.

Can modifier 50 be used for bilateral CNS administration?

No. CMS identifies bilateral adjustment as inappropriate for this code.

What documentation supports 96450?

Record the medication, the CNS route, the access method, and that administration was completed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included.

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.
