Recent data indicate a contraction in radiation oncology availability across the United States, coinciding with proposed federal adjustments to outpatient reimbursement structures.

近期數據顯示，全美放射腫瘤科的可用性正在縮減，這與聯邦政府擬議調整門診報銷結構的時間相吻合。

An analysis published in the International Journal of Radiation Oncology*Biology*Physics reveals a systemic reduction in radiation therapy access between 2018 and 2025. The data indicate that over 50 million citizens reside in counties devoid of radiation oncology practice sites. A critical disparity exists between urban and rural environments; while urban centers typically maintain redundant treatment options, the closure of a single facility in a rural county frequently results in the total eradication of local access. This vulnerability is most acute among independent, non-hospital-affiliated centers, which lack the institutional capital necessary to mitigate operational disruptions. Furthermore, these closures are disproportionately concentrated in regions characterized by lower median incomes and higher rates of uninsured populations.

發表在《國際放射腫瘤、生物學與物理學期刊》的一項分析顯示，2018 年至 2025 年間，放射治療的獲取渠道出現了系統性減少。數據指出，超過 5,000 萬名公民居住在完全沒有放射腫瘤科診所的縣。城市與鄉村環境之間存在嚴重差異；城市中心通常保有冗餘的治療選擇，但在鄉村縣，單一設施的關閉往往會導致當地服務完全消失。這種脆弱性在獨立且非醫院附屬的中心最為顯著，因為它們缺乏足以緩解營運中斷的機構資金。此外，這些關閉情況不成比例地集中在收入中位數較低且無保險人口比例較高的地區。

Concurrent with these trends, the Centers for Medicare & Medicaid Services (CMS) has proposed a 2027 outpatient payment rule to implement 'site-neutral' payments for specific imaging services, such as X-rays, CT, and MRI scans. This policy seeks to eliminate the payment premium currently afforded to hospital-owned outpatient departments, aligning their reimbursement with the physician fee schedule. While CMS projects a reduction in Medicare spending by approximately $260 million and a decrease in beneficiary cost-sharing by $70 million, the measure has encountered institutional opposition. Critics argue that such reductions may exacerbate the financial instability of hospitals, particularly those in vulnerable regions, potentially precipitating further service contractions.

與這些趨勢同步，醫療保險和醫療補助服務中心 (CMS) 擬定了 2027 年門診支付規則，針對特定影像服務（如 X 光、CT 和 MRI 掃描）實施「機構中立」支付。此政策旨在取消目前賦予醫院所有門診部門的支付溢價，將其報銷標準與醫師收費表對齊。儘管 CMS 預計 Medicare 支出將減少約 2.6 億美元，且受益人分攤成本將降低 7,000 萬美元，但該措施遭遇了機構對抗。批評者認為，此類削減可能會加劇醫院（尤其是脆弱地區醫院）的財務不穩定，潛在地促使服務進一步縮減。

Institutional stakeholders have highlighted a temporal convergence of these pressures. Dr. Vivek S. Kavadi of ASTRO noted that the observed decline in access preceded the 2026 Medicare reimbursement reductions, suggesting a pre-existing fragility in the provider network. To counteract this erosion, proponents have suggested legislative interventions, such as the bipartisan Radiation Oncology Case Rate (ROCR) Act, to establish a more predictable financial framework for providers.

機構利益相關者強調了這些壓力在時間上的趨同性。ASTRO 的 Vivek S. Kavadi 博士指出，觀察到的獲取渠道下降早於 2026 年 Medicare 報銷削減之前就已發生，顯示供應商網絡預先存在脆弱性。為了對抗這種侵蝕，支持者建議採取立法干預，例如跨黨派的《放射腫瘤科個案率 (ROCR) 法案》，以為供應商建立一個更可預測的財務框架。

The United States faces a dual challenge of declining rural cancer care access and a transition toward site-neutral reimbursement models that may further impact provider viability.

美國面臨雙重挑戰：鄉村癌症治療獲取渠道減少，以及向機構中立報銷模式過渡，而後者可能會進一步影響供應商的生存能力。
