What Q5126 covers

Alymsys is a bevacizumab biosimilar used intravenously in oncology regimens for selected cancers, including colorectal, non-squamous lung, renal, cervical, and ovarian cancers. Oncology practices, infusion centers, and hospital outpatient departments may report this drug code when Alymsys is administered. The code identifies the specific product, not bevacizumab products generally; use it when Alymsys was the product supplied.

CMS assigns this code physician fee schedule status E, meaning it is excluded from the physician fee schedule. When Medicare covers the drug, it is treated as a Part B drug and generally priced through CMS’s quarterly Average Sales Price drug pricing files; coverage is left to the Medicare contractor’s judgment. Each billing unit represents 10 mg of bevacizumab-maly. Report the administered dose in 10 mg units, and report the infusion administration service separately when furnished and supported by the claim.

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.

Payment rules and modifiers for Q5126

Q5126 has no global surgery period, no multiple-procedure, bilateral or assistant-at-surgery adjustment, and no professional/technical split. What changes the payment is where the service happens: the place of service on the claim decides whether Medicare pays the office or the facility rate.

Q5126 billing questions

When should a practice use Q5126 instead of another bevacizumab code?

Use Q5126 when the administered product was Alymsys (bevacizumab-maly). Other bevacizumab products have their own HCPCS codes.

How many milligrams does one unit represent?

One unit represents 10 mg of bevacizumab-maly. Calculate units from the administered dose in 10 mg increments.

Does Q5126 include the infusion administration?

No. Q5126 identifies the drug; report the infusion administration service separately when it was furnished and is supported by the claim.

How does Medicare treat Q5126?

CMS assigns status E, excluding it from the physician fee schedule. When covered, it is a Part B drug generally priced using CMS’s quarterly ASP drug pricing files, and coverage is left to the Medicare contractor’s judgment.

What should the medical record support?

Document that Alymsys was administered and record the dose given. The product and dose documentation should support the reported units.

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.
