HCPCS code J9022: Atezolizumab injection, per 10 mg2026 Medicare rate & RVUs in Illinois

CMS doesn’t publish an office rate for J9022 in Illinois.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What J9022 covers

Atezolizumab is an intravenous monoclonal antibody that blocks PD-L1, an immune checkpoint protein. Oncology clinicians use it in treatment regimens for several cancers, including lung, bladder, and liver cancers. The drug is administered by infusion in settings such as a physician’s office or hospital outpatient department. Atezolizumab may be given alone or with other cancer drugs; the regimen and administration service are distinct from the drug itself.

J9022 represents 10 mg of atezolizumab, so 1,200 mg corresponds to 120 units. CMS excludes the code from the physician fee schedule (status E). When Medicare covers the drug, payment is under another method; CMS classifies it as a Part B drug generally priced using its quarterly Average Sales Price drug files. Coverage is left to the Medicare contractor’s judgment. Report the drug units separately from any applicable infusion administration service.
