Frequently Asked Questions
What is the chemo administration code hierarchy?
Per encounter, only ONE 'initial' code per IV access (in physician office). Initial codes: 96413 (chemo IV infusion 1st hr), 96409 (chemo IV push initial), 96365 (non-chemo IV infusion 1st hr), 96374 (non-chemo IV push initial). Each addt'l hour of same drug: 96415 (chemo) or 96366 (non-chemo). Each addt'l SEQUENTIAL different drug: 96417 (chemo) or 96367 (non-chemo). Concurrent (multiple drugs running at same time): 96368.
When do I use JW vs JZ?
JW = drug or biological wasted/discarded from a single-use vial (Medicare requires reporting wasted units along with administered units). JZ (added July 2023) = ZERO drug wasted from single-use vial (must be reported when no waste). One must be reported on every claim line for single-use vial drugs from Medicare. Multi-use vials don't require JW/JZ.
How do I sequence Z51 codes with cancer diagnoses?
When admission/encounter is FOR chemo (Z51.11), radiation (Z51.0), or immunotherapy (Z51.12), the Z51 code is PRINCIPAL/FIRST-LISTED, then the malignancy. When admission is for management of a complication (anemia, neutropenia, dehydration from chemo side effect), the COMPLICATION is principal. Personal history (Z85.x) is used when patient is no longer being actively treated.
