Chemotherapy administration
About 96542: CNS chemotherapy through implanted reservoir
Report this service when antineoplastic medication is administered into the central nervous system through an implanted reservoir, such as an Ommaya reservoir.
This service covers delivery of antineoplastic medication into the cerebrospinal fluid or ventricular system through an implanted reservoir. It is commonly performed by an oncologist, neuro-oncologist, or other qualified clinician treating a patient who needs CNS-directed chemotherapy and has an access reservoir in place. An Ommaya reservoir is a typical example; the defining feature is administration through the reservoir rather than by a spinal puncture.
Select the code when the record supports CNS chemotherapy administered through that access route. Document the medication, dose, administration date, and route through the reservoir, along with the clinical indication. Distinguish the drug administration from routine device care or irrigation, and do not select the code solely because a reservoir is present. This service is not time-based; the documentation should establish the administration performed.
