Importance The federal Hospital Price Transparency final rule, which became effective in 2021, requires hospitals to publicly disclose payer-specific prices for drugs. However, little is known about hospital markup prices for parenterally administered therapies. Objective To assess the extent of price markup by hospitals on parenterally administered cancer therapies and price variation among hospitals and between payers at each hospital. Design, Setting, and Participants A cross-sectional analysis was conducted of private payer-specific negotiated prices for the top 25 parenteral (eg, injectable or infusible) cancer therapies by Medicare Part B spending in 2019 using publicly available hospital price transparency files. Sixty-one National Cancer Institute (NCI)-designated cancer centers providing clinical care to adults with cancer were included. The study was conducted from April 1 to October 15, 2021. Exposures Estimated hospital acquisition costs for each cancer therapy using participation data from the federal 340B Drug Pricing Program. Main Outcomes and Measures The primary outcome was hospital price markup for each cancer therapy in excess of estimated acquisition costs. Secondary outcomes were the extent of across-center price ratios, defined as the ratio between the 90th percentile and 10th percentile median prices across centers, and within-center price ratios, defined as the ratio between the 90th percentile and 10th percentile prices between payers at each center. Results Of 61 NCI-designated cancer centers, 27 (44.3%) disclosed private payer-specific prices for at least 1 top-selling cancer therapy as required by federal regulations. Median drug price markups across all centers and payers ranged between 118.4% (sipuleucel-T) and 633.6% (leuprolide). Across-center price ratios ranged between 2.2 (pertuzumab) and 15.8 (leuprolide). Negotiated prices also varied considerably between payers at the same center; median within-center price ratios for cancer therapies ranged from 1.8 (brentuximab) to 2.5 (bevacizumab). Conclusions and Relevance Most NCI-designated cancer centers did not publicly disclose payer-specific prices for cancer therapies as required by federal regulation. The findings of this cross-sectional study suggest that, to reduce the financial burden of cancer treatment for patients, institution of public policies to discourage or prevent excessive hospital price markups on parenteral chemotherapeutics might be beneficial.
