Although these goals are critical, the legislation may have unintentional adverse impacts on long-term care (LTC) pharmacies. This article examines how specific provisions of The Inflation Reduction Act of 2022 may destabilize the LTC pharmacy sector, creating barriers to access for LTC residents.We analyze the financial implications of the Medicare Drug Price Negotiation Program, illustrating how the shift to maximum fair price reimbursement combined with inadequate dispensing fees could result in an estimated revenue decline of more than 85% for drugs selected within the program. We also outline how new payment flows for the maximum fair price involving the Medicare Transaction Facilitator will likely extend reimbursement timelines, creating liquidity challenges for pharmacies operating on thin margins.Beyond finances, we discuss operational conflicts with the Medicare Prescription Payment Plan. Specifically, we argue that alerting requirements are incompatible with LTC workflows and pose unnecessary administrative burden on pharmacies. To address these vulnerabilities, we propose near-term legislative and regulatory remedies, including appropriating funds to ensure timely manufacturing payments and codifying the standard default refund amount to protect acquisition discounts. Finally, we recommend structural reforms that shift reimbursement away from volume-based models to value-based care. By aligning payment with patient outcomes, policymakers can ensure the financial sustainability of LTC pharmacies and the continued delivery of highly effective pharmaceutical care to the nation's aging population.</p>","PeriodicalId":16170,"journal":{"name":"Journal of managed care & specialty pharmacy","volume":" ","pages":"498-506"},"PeriodicalIF":3.3,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13020388/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146157222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

About 25% of adults with ALL have the more aggressive Philadelphia chromosome-positive (Ph+) subtype. Standard treatment includes tyrosine kinase inhibitors (TKIs) in combination with chemotherapy or corticosteroids, which have greatly enhanced survival rates over the past 2 decades. Ponatinib, a third-generation TKI demonstrated greater efficacy compared with imatinib, a first-generation TKI, in the PhALLCON trial.</p><p><strong>Objective: </strong>To conduct an economic evaluation of ponatinib compared with (1) reference imatinib, (2) the average cost of several imatinib generics, and (3) the weighted cost of imatinib in adults with Ph+ ALL from the US payer perspective.</p><p><strong>Methods: </strong>Cost-effectiveness and cost-utility analyses were performed using a partitioned survival model with 3 mutually exclusive health states: progression-free, progressed disease, and death. A time horizon of 60 months and a 3% discount rate were applied. The incremental costs per 1% gain in probability of progression-free survival and overall survival at 60 months were estimated.</p><p><strong>Results: </strong>Life-years (LYs) and quality-adjusted LYs (QALYs) were higher for ponatinib (3.74, 2.15) than for imatinib (3.52, 1.68). Compared with reference imatinib, ponatinib was dominant, having cost savings of $56,024. Compared with average generic imatinib, ponatinib had an incremental cost of $147,147, yielding an incremental cost-effectiveness ratio (ICER) of $668,150 per LY gained and incremental cost-utility ratio (ICUR) of $314,646 per QALY gained. Compared with weighted imatinib, ponatinib had an incremental cost of $128,861, yielding ICER of $585,122 per LY gained and ICUR of $275,546 per QALY gained. The differential cost of ponatinib per patient for a 1% increase in the probability of remaining in the progression-free survival state was $6,883 in savings compared with reference imatinib, but an additional $18,077 compared with average generic imatinib and $15,835 compared with weighted imatinib.</p><p><strong>Conclusions: </strong>Ponatinib demonstrated cost savings relative to reference imatinib, though its incremental costs were substantially higher when compared with both average and weighted imatinib, for an approximate gain of 3 months of life and 6 months of quality-adjusted life. This presents a value dilemma: whether to save money with more affordable alternatives for a slightly lower clinical benefit, possibly parlaying these cost-efficiencies into expanded patient access. This highlights the challenge of balancing clinical benefits with economic sustainability, particularly when the modest health gains come at a substantially higher cost. Although ponatinib offers therapeutic value, payers and policymakers must carefully evaluate whether the clinical outcomes justify the additional costs, considering also its ","PeriodicalId":16170,"journal":{"name":"Journal of managed care & specialty pharmacy","volume":"32 4","pages":"413-421"},"PeriodicalIF":3.3,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13020392/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147512756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
