    ommaya is intraventricular and the reservoir is placed SQ so the 96542 is accurate.

    Other than the 96542 and the Methotrexate J code for the injection of the methotrexate, is there any other procedures that are involved in the withdrawing of the spinal fluid through the Ommaya Reservoir?

    Check out code 61070. I am not current on the use of this code. This is not something we do regularly but it's a place to start. We have used this code (with applicable modifier) when a sample of fluid was taken for culture just prior to the chemo admin via the ommaya. Make sure your documentation supports additional code and use -59 if supported. There was an article in Oncology Coding Alert about this many years ago.

    Good luck!
