Let me concede that there is only limited evidence that hospitals engage in what’s called “dynamic cost shifting.” That is, if a hospital’s uncompensated care burden rises by $1 million, only some, not all, of that amount can be expected to be recovered by the hospital’s increasing charges to privately insured patients to make up the difference.
That said, hospitals can and do exercise market power, meaning they are able to charge private patients a higher rate than Medicare or Medicaid patients. This practice results in profits from private patients that then are used by the hospital in various ways, including the provision of charitable care.
The point being that if the federal government eliminated whatever payments it now makes for uncompensated care (including that generated by unauthorizedimmigrants), hospitals hypothetically would not respond by increasing charges to recover part of their increased uncompensated care costs, but instead make adjustments in the form of either spending less on other things or taking steps to discourage unauthorizedimmigrants from showing up at their doors.
Conversely, if federal, state or local governments were to make hospitals entirely whole regarding their uncompensated care losses to unauthorized immigrants, this would not necessarily benefit hospital patients in the form of lower charges. For these reasons, it is not altogether obvious that these hospital uncompensated care losses are a problem that can be solved by better public policy. Nevertheless they manifestly are a public policy issue from the standpoint of patients concerned about high health costs.
Physician Charity Care. The $1.5 billion in physician charity care represent an average of $1,750 for each of the country’s 855,000 active physicians. According to Medscape’s Physician Compensation Report for 2017, the average physician makes $294,000 a year. Even generously assuming a 60 hour workweek, that’s roughly $100 hourly meaning the average physician devotes 17.5 hours a year to charity care for unauthorized immigrants (less if we assume a higher hourly rate).
Note that physicians, receive no tax benefits for providing charity care; that is, they cannot write off the cost of charity care from their personal or business taxes. Consequently, although physician charity care is an important component of the uncompensated care landscape, in my view, these voluntary donations of time–a longstanding worthy tradition in American medicine–do not pose a public policy concern.
Other Federal Subsidies Benefiting Unauthorized Immigrants
Although it presumably did not arise by a deliberate intent to benefit unauthorizedimmigrants, current tax policy likely confers an additional $6.6 billion in additional benefits financed by U.S. taxpayers. The tax exemption for nonprofit hospitals (and any other nonprofit health facilities) benefits unauthorized immigrants regardless of their insurance status. The employer tax exclusion benefits unauthorized immigrants who happen to receive employer-provided health benefits.
Tax Exemption. The value of the nonprofit tax exemption to U.S. nonprofit hospitals in 2011 was $24.6 billionincluding forgone taxes, public charitable contributions, and the value of tax-exempt bond financing. Assuming that 11.3 million unauthorized immigrants receive a pro rata share of this benefit, they receive roughly $0.9 billion in additional federal subsidies for their hospital care. I could locate no parallel figures for other nonprofit health facilities.
Employer Tax Exclusion. Estimating the size of these tax benefits for unauthorizedimmigrants is of necessity extremely rough. I could locate no reliable information on the wage distribution of such immigrants, especially among those who obtain employer-provided health benefits. According to Kaiser Family Foundation, “nonelderly lawfully present and unauthorized immigrants are as likely as nonelderly citizens are to live in a family with at least one full-time worker, but they are more likely than citizens are to be low-income, since they often work in low-wage jobs.” More concretely, nearly half (48%) of unauthorized immigrants live in low income families below 200% of the federal poverty level.
That said, as shown earlier, we know that only 3.9 million of unauthorized immigrants are uninsured, leaving 7.7 million with some sort of coverage. No good data exist on what fraction of these obtain non-group health coverage, but Kaiser Family Foundation’s Larry Levitt has said via Twitter that “some are buying non-group, but I’d agree that it’s primarily employer coverage.”  Assuming that 86% have employer-provided coverage (which is the identical percentage among all non-elderly adults having private coverage in 2016: Table HIC-2), this would equal 6.6 million unauthorized immigrants with such coverage.
And even if we conservatively assume that such workers obtain the least expensive form of coverage (high deductible health plan with savings option) in an industry most likely to employ such workers (agriculture/mining/construction), the single premium in 2017 would be $5,666 (compared to $6,690 across all plans/industries). If we further conservatively assume all unauthorized workers pay no income taxes and are only liable for payroll taxes, the tax subsidy amounts to 15.3% ($866 per worker) or $5.7 billion for all unauthorizedimmigrants with such coverage.
Conclusion
When we sum all the figures, including $11.9 billion for the uninsured and another $6.6 billion in tax subsidies, we arrive at a grand total of $18.5 billion in subsidized health care for all unauthorized immigrants in 2016. This amounts to $57 per U.S. resident. The share that concerns me the most–$11.2 billion borne by federal taxpayers–amounts to $34 per U.S. resident. Admittedly, one could argue that since the amounts at stake are so small, this is not an issue worth fighting about. However, it is precisely that sort of thinking that has led us to today’s dismal reality that unfunded liabilities facing Uncle Sam now are roughly $200 trillion and rising.
So even though the dollar stakes are quite small in a federal budget that will spend $4 trillion in the fiscal year that just started, I believe citizens and federal policymakers should stop pressing the Easy button and seriously ponder four important principled arguments against federal tax financing of health care for unauthorized immigrants:
  • Federal funding is unnecessary
  • Federal funding is inefficient
  • Federal funding is unconstitutional
  • Federal funding is immoral
I will elaborate on these arguments in a subsequent post.
Update #1: February 28, 2018
Twitter user d-dask pointed out that the term I originally used in this piece–undocumented immigrants–is not the same term used by Department of Homeland Security. Even though I used “undocumented immigrants” with the intent that it be viewed as a neutral term, I concluded that using the “official” DHS term was preferable, so have substituted this term throughout.
