Access to Medicare
Part B Therapies

More than 60% of cancer patients in the United States rely on Medicare, many of whom receive outpatient treatment from Medicare Part B to cover the cost of chemotherapy drugs.

Under Medicare Part B, community cancer clinics are reimbursed for chemotherapy drugs based on a formula that consists of the drug’s average sales price (ASP) and an additional payment of 6% to cover the administrative costs associated with the handling, storage, preparation, dispensing, and disposal of these highly sensitive drugs. Evidence suggests that the current Part B drug payment system has been successful in ensuring patient access while moderating the cost of these services for the Medicare program. According to the 2017 Medicare Trustee’s Report, spending on Part B drugs accounted for just 3% of total Medicare spending and has remained relatively stable over the years.

Unfortunately, a series of misguided federal policies have created an unsustainable situation whereby many community cancer care providers are forced to operate at a loss when providing treatment to Medicare patients. That’s because, over the years, the federal government has moved forward with numerous reimbursement cuts and payment demonstrations that threaten the integrity of the Medicare Part B drug payment formula. As a result, since 2008, more than 1,200 community cancer care centers have closed, consolidated, or reported financial problems, creating access issues for patients and increased costs to the Medicare program.

Step Therapy for Medicare Advantage Plans

The Centers for Medicare and Medicaid Services (CMS) announced their intention to rescind prior guidance that had prohibited step therapy for Part B drugs and issued new guidance that will allow Medicare Advantage (MA) plans to apply step therapy for Part B drugs, beginning January 1, 2019.

The Trump Administration claimed that this action is an effort to reduce prescription drug costs through better negotiation, a component of the “American Patients First” drug pricing blueprint.

The Network will closely monitor and examine the impact of this announcement and will work with CMS and MA plans to ensure cancer patients continue to have timely access to appropriate and tailored treatments.


In 2011, Congress enacted the Budget Control Act of 2011 which applied a mandatory 2% sequester cut to Part B drugs. Additionally, when the ASP+6% formula was first introduced, Congress required that the prompt pay discounts that pharmaceutical manufacturers extend to distributors for timely payment be included in the calculation of ASP, further lowering the reimbursement centers receive.

As a result of the sequester cut and the prompt pay inclusion, the true amount that community cancer centers receive for administering Part B drugs is equivalent to approximately ASP+2.3% – and that’s if the centers are able to obtain drugs at ASP in the first place. Many small and rural community cancer centers are unable to leverage the buying power of larger centers and end up paying higher than ASP to acquire certain drugs.

There are several ways that the Administration and Congress can act to avoid the most devastating sequestration impacts. CMS has the authority to exempt cancer drugs from the sequester cut or to apply the 2% sequester cut only to the 6% services payment. Additionally, Congress can pass legislation to exclude prompt pay discounts from the calculation of ASP.

In response to the COVID-19 pandemic, Congress temporarily suspended sequester payment cuts through March 31, 2022. A 1% sequester is scheduled to begin on April 1, 2022 before the full 2% sequester returns on July 1, 2022.

The Part B Demonstration Project

In 2016, the Centers for Medicare & Medicaid Services issued a proposal to modify physician administered drug reimbursement based on geographic areas.

Under the proposed payment model, Medicare would reduce payment for Part B drugs from the current ASP+6% payment formula to ASP+2.5% with a flat fee of $16.80 per drug per day administered. The US Oncology Network joined several other cancer community stakeholders in urging CMS to abandon the model, arguing that there is no evidence that the payment changes contemplated by CMS would improve quality of care or reduce spending. Furthermore, changes would have incentivized the underutilization of breakthrough cancer therapies and could have resulted in increased healthcare spending on patients over the long term.

Thanks to the advocacy efforts of The US Oncology Network and other industry stakeholders, CMS put the Part B Demonstration on hold in late 2016, and permanently canceled the program in 2017.
