96411 and 96416 on the same day: a chemo push and a pump infusion of the same drug

The rule that pairs them

NCCI Policy Manual Chapter XI, Section N.5, quoted in full for the pump side:

“CPT code 96522 (Refilling and maintenance of implantable pump or reservoir for drug delivery, systemic (e.g., intravenous, intra-arterial) and CPT code 96521 (Refilling and maintenance of portable pump) shall not be reported with CPT code 96416 (Initiation of prolonged intravenous chemotherapy infusion (more than 8 hours), requiring use of a portable or implantable pump) or CPT code 96425 … CPT codes 96416 and 96425 include the initial filling and maintenance of a portable or implantable pump. CPT codes 96521 and 96522 are used to report subsequent refilling of the pump.” — NCCI Ch. XI §N.5

On the push side, 96411 is CPT’s add-on for each additional chemotherapy substance given by IV push; it is reported in addition to the encounter’s initial code, which on a FOLFOX day is the oxaliplatin infusion (96413). The bolus and the pump infusion are two administrations by two techniques; nothing in the manual folds a push into a pump start or vice versa.

FOLFOX, line by line

Day 3, pump disconnect: if the pump is simply disconnected and no refill occurs, there is no 96521; a disconnect visit with a nurse assessment is generally reported with the appropriate E/M or not at all, depending on payer policy. 96521 is reported when a portable pump is refilled at a later encounter. The drug quantity for the pump is reported on the day the drug was supplied and the infusion started.

Variants that change the lines

• No oxaliplatin (5-FU/leucovorin alone). There is no infusion initial code, so the bolus is the initial chemo push: 96409 instead of 96411, then 96416 for the pump. A 2-hour leucovorin infusion is not 96365 either — the chemo push outranks it in the hierarchy, so leucovorin is reported as a sequential non-chemo infusion, 96367, with 96366 for its additional hour.
• Bolus omitted. Drop 96411; 96416 stands on its own alongside the oxaliplatin lines.
• Hospital outpatient department. The same CPT logic applies under OPPS; the pump start and the push remain separate lines.

Medicare-basis pricing for each line is in the Code this visit tool on the chemo push page.

Frequently asked questions

Can 96411 and 96416 be billed together when it is the same drug (5-FU bolus and 5-FU pump)?

Yes. They describe two administrations by two techniques — an additional IV push and the initiation of a prolonged pump infusion. CPT’s “additional substance” language for 96411 refers to a push in addition to the initial service, and NCCI does not bundle 96411 into 96416 or the reverse. Chart the bolus with its own time and the pump start separately.

Do I bill 96521 when I connect the pump?

No. NCCI Ch. XI §N.5 states that 96416 includes the initial filling and maintenance of the pump, and that 96521 is used to report subsequent refilling. 96521 belongs on a later visit where the pump is actually refilled.

What if the patient gets 5-FU/leucovorin without oxaliplatin?

With no chemo infusion on the day, the 5-FU bolus becomes the initial service, 96409, instead of the add-on 96411. The pump start is still 96416, and the leucovorin infusion is reported as a sequential non-chemo infusion (96367) because the chemo push outranks it in the initial-service hierarchy.

How many units of J9190 go on the claim?

The total fluorouracil administered and started that day — the bolus dose plus the dose loaded into the pump — converted at the HCPCS descriptor (J9190 is per 500 mg). Waste, if any, follows the single-dose-vial JW/JZ rules; the units calculator does the arithmetic.
