By: Andrew Silverio, Esq. Anyone who works in health benefits is familiar with surprise billing – the specific kind of balance billing which occurs when a patient visits an in-network physician or hospital, and receives an unexpected balance bill from an out-of-network provider that they didn’t have an opportunity to select, and in many cases, didn’t even know they had utilized. Common culprits are anesthesiologists, assistant surgeons, and outside lab work. We often think of this as primarily a problem for emergency claims. This makes a great deal of sense, since when someone presents at an ER or is brought there via ambulance, they likely won’t have an opportunity to ask questions about network participation or request specific providers. However, according to surprising data released in the Journal of the American Medical Association on February 11, 2020 entitled “Out-of-Network Bills for Privately Insured Patients Undergoing Elective Surgery With In-Network Primary Surgeons and Facilities (available at jamanetwork.com/journals/jama/fullarticle/2760735?guestAccessKey=9774a0bf-c1e7-45a4-b2a0-32f41c6fde66&utm_source=For_The_Media&utm_medium=referral&utm_campaign=ftm_links&utm_content=tfl&utm_term=021120), these bills don’t actually seem to be more likely to arise from emergencies or other hospital stays where patients have less of an opportunity to “shop around.” The study looked at 347,356 patients undergoing elective surgeries, at in-network facilities with in-network surgeons. These are patients who had ample opportunity to select their providers, and indeed did select in-network providers for both the surgeon performing their procedure and the facility in which it would occur. Shockingly, over 20% of these encounters resulted in a surprise out of network bill (“Among 347 356 patients who had undergone elective surgery with in-network primary surgeons at in-network facilities . . . an out-of-network bill was present in 20.5% of episodes...”) The instances that involved surprise bills also corresponded to higher total charges - $48,383.00 in surprise billing situations versus $34,300.00 in non-surprise billing situations. The most common culprits were surgical assistants, with an average surprise bill of $3,633.00, and anesthesiologists, with an average bill of $1,219.00. In the context of previous research indicating that “20 percent of hospital admissions that originated in the emergency department . . . likely led to a surprise medical bill,” it seems that even when patients are able to do their homework and select in-network facilities and surgeons, they are just as susceptible to surprise billing. ( See Garmon C, Chartock B., One In Five Inpatient Emergency Department Cases May Lead To Surprise Bills. Health Affairs , available at healthaffairs.org/doi/10.1377/hlthaff.2016.0970.) Many states have enacted protections against balance billing and surprise billing, with Washington and Texas both recently enacting comprehensive legislation. However, these state-based laws have limited applicability, and there are to date no meaningful federal protections for patients in these situations. Until such protections are enacted, patients are left vulnerable to sometimes predatory billing practices, and plans are left to choose between absorbing that financial blow or leaving patients out in the cold.
