Medical liability insurance covers physicians’ liability, and its price could affect physicians’ practice. In this article, we use a unique county-level dataset to study how medical liability insurance prices of three specialties, internal medicine, general surgery, and obstetrics–gynecology (OB-GYN), changed after the Affordable Care Act (ACA) elective Medicaid expansion provision. The Medicaid expansion has largely increased the demand for health care services and potentially exposed physicians to higher medical liability risks. With higher expected losses, insurers could react by increasing medical malpractice insurance prices. We first study all counties in states that elected to expand Medicaid and compare them to counties in nonexpansion states. Then we narrow our analysis to consider differential effects in bordering counties with different Medicaid expansion statuses over the period 2010–2018. In both samples, we find significantly higher medical liability insurance prices 2 years after the expansion (on average) in expansion states in comparison to nonexpansion states, and the difference is larger for physicians practicing internal medicine (6–8% at 2 years after expansion) and general surgery (12–16% at 2 years after expansion) but less so for OB-GYN. Our OB-GYN results are likely because significant numbers of births were already covered under Medicaid and were not affected by the expansion. Our finding suggests that the expansion of health insurance increases liability costs to medical practitioners.

公共健康保险的扩展是否会影响医疗责任保险的价格?ACA 可选医疗补助扩展案例

医疗责任保险涵盖医生的责任,其价格可能会影响医生的执业。在本文中,我们使用一个独特的县级数据集来研究内科、普通外科和妇产科 (OB-GYN) 三个专业的医疗责任保险价格在《平价医疗法案》(ACA) 选择性医疗补助之后如何变化扩展规定。医疗补助的扩张很大程度上增加了对医疗保健服务的需求,并可能使医生面临更高的医疗责任风险。由于预期损失较高,保险公司可以通过提高医疗事故保险价格来应对。我们首先研究选择扩大医疗补助的州的所有县,并将它们与未扩大医疗补助的州的县进行比较。然后,我们缩小分析范围,考虑 2010 年至 2018 年期间具有不同医疗补助扩张状态的边境县的差异效应。在这两个样本中,我们发现扩张后两年(平均),扩张州的医疗责任保险价格明显高于非扩张州,并且内科医生的差异更大(扩张后两年为 6-8%) )和普通外科(扩张后 2 年为 12-16%),但妇产科的情况较少。我们的妇产科结果很可能是因为大量的出生已经享受到医疗补助,并且没有受到扩大的影响。我们的研究结果表明,健康保险的扩大增加了医生的责任成本。我们发现,与非扩张州相比,扩张州扩张后(平均)两年的医疗责任保险价格明显更高,而且内科医师(扩张后两年为 6-8%)和普通外科医师的差异更大(扩张后 2 年为 12-16%),但妇产科的情况较少。我们的妇产科结果很可能是因为大量的出生已经享受到医疗补助,并且没有受到扩大的影响。我们的研究结果表明,健康保险的扩大增加了医生的责任成本。我们发现,与非扩张州相比,扩张后两年(平均)医疗责任保险价格明显更高,而且内科医师(扩张后 2 年为 6-8%)和普通外科医师的差异更大(扩张后 2 年为 12-16%),但妇产科的情况较少。我们的妇产科结果很可能是因为大量的出生已经享受到医疗补助,并且没有受到扩大的影响。我们的研究结果表明,健康保险的扩大增加了医生的责任成本。内科医师(扩张后 2 年为 6-8%)和普通外科医师(扩张后 2 年为 12-16%)差异较大,但妇产科医师差异较小。我们的妇产科结果很可能是因为大量的出生已经享受到医疗补助,并且没有受到扩大的影响。我们的研究结果表明,健康保险的扩大增加了医生的责任成本。内科医师(扩张后 2 年为 6-8%)和普外科医师(扩张后 2 年为 12-16%)差异较大,但妇产科医师差异较小。我们的妇产科结果很可能是因为大量的出生已经享受到医疗补助,并且没有受到扩大的影响。我们的研究结果表明,健康保险的扩大增加了医生的责任成本。
