In September 2022, Elyse Greenblatt of Queens returned home from a trip to Rwanda with a rather unwelcome-back gift: persistent congestion.
She felt a pain in her sinuses and sought a quick resolution.
Covid-19 couldn鈥檛 be ruled out, so rather than risk passing on an unknown infection to others in a waiting room, the New Yorker booked a telehealth visit through her usual health system, Mount Sinai 鈥 a perennial on best-hospitals lists.
That proved an expensive decision. She remembers the visit as taking barely any time. The doctor decided it was likely a sinus infection, not covid, and prescribed her fluticasone, a nasal spray that relieves congestion, and an antibiotic, Keflex. (The Centers for Disease Control and Prevention 鈥渁re not needed for many sinus infections, but your doctor can decide if you need鈥 one.)
Then the bill came.
The Patient: Elyse Greenblatt, now 38, had insurance coverage through Empire BlueCross BlueShield, a New York-based insurer.
Medical Services: A telehealth urgent care visit through Mount Sinai鈥檚 personal record app. Greenblatt was connected with an urgent care doctor through the luck of the draw. She was diagnosed with sinusitis, prescribed an antibiotic and Flonase, and told to come back if there was no improvement.
All this meant a big bill. The insurer said the telehealth visit was deemed an out-of-network service 鈥 a charge Greenblatt said the digital service didn鈥檛 do a great job of warning her about. It came as a surprise. 鈥淚n my mind, if all my doctors are 鈥榠n-insurance,鈥 why would they pair me with someone who was 鈥榦ut-of-insurance鈥?鈥 she asked. And the hospital system tried its best to make contesting the charge difficult, she said.
Service Provider: The doctor was affiliated with Mount Sinai鈥檚 health system, though where the bill came from was unclear: Was it from one of the system鈥檚 hospitals or another unit?
Total Bill: $660 for what was billed as a 45- to 59-minute visit. The insurer paid nothing, ruling it out of network.
What Gives: The bill was puzzling on multiple levels. Most notably: How could this be an out-of-network service? Generally, urgent care visits delivered via video are a competitive part of the health care economy, and they鈥檙e not typically terribly expensive.
Mount Sinai鈥檚 telehealth booking process is at pains to assure bookers they鈥檙e getting a low price. After receiving the bill, Greenblatt went back to the app to recreate her steps 鈥 and she took a screenshot of one particular part of the app: the details. She got an estimated wait time of 10 minutes, for a cost of $60. 鈥淐ost may be less based on insurance,鈥 the app said; this information, Mount Sinai spokesperson Lucia Lee said, is 鈥渇or the patient鈥檚 benefit,鈥 and the 鈥渃ost may differ depending on the patient鈥檚 insurance.鈥
A $60 fee would be in line with, if not a bit cheaper than, many other telehealth services. Doctor on Demand, for example, from a clinician for $79 for a 15-minute visit, assuming the customer鈥檚 insurance doesn鈥檛 cover it. Amazon鈥檚 new clinic service, offering telehealth care for a wide range of conditions, advertises that for a sinus infection.
The Health Care Cost Institute, an organization that analyzes health care claims data, told 杨贵妃传媒視頻 Health News its data shows an urgent care telehealth visit runs, on average, $120 in total costs 鈥 but only $14 in out-of-pocket charges.
So how did this visit end up costing astronomically so much more than the average? After all, one of the selling points of telemedicine is not only convenience but cost savings.
First, there was the length of the visit. The doctor鈥檚 bill described it as moderately lengthy. But Greenblatt recalled the visit as simple and straightforward; she described her symptoms and got an antibiotic prescription 鈥 not a moderately complex visit requiring the better part of an hour to resolve.
The choice of description is a somewhat wonky part of health care billing that plays a big part in how expensive care can get. The more complex the case, and the longer it takes to diagnose and treat, the more providers can charge patients and insurers.
Greenblatt鈥檚 doctor billed her at a moderate level of care 鈥 curious, given her memory of the visit as quick, almost perfunctory. 鈥淚 think it was five minutes,鈥 she recalled. 鈥淚 said it was a sinus infection; she told me I was right. 鈥楾ake some meds, you鈥檒l be fine.鈥欌
Ishani Ganguli, a doctor at Brigham and Women鈥檚 Hospital in Boston who studies telehealth, said she didn鈥檛 know the exact circumstances of care but was 鈥渁 bit surprised that it was not billed at a lower level鈥 if it was indeed a quick visit.
That leaves the out-of-network aspect of the bill, allowing the insurer to pay nothing for the care. (Stephanie DuBois, a spokesperson for Empire BlueCross BlueShield, Greenblatt鈥檚 insurer, said the payer covers virtual visits through two services, or through in-network doctors. The Mount Sinai doctor fit neither criteria.) Still, why did Mount Sinai, Greenblatt鈥檚 usual health care system, assign her an out-of-network doctor?
鈥淚f one gets their care from the Mount Sinai system and the care is within network, I don鈥檛 think it is reasonable for the patients to expect or understand that one of the Mount Sinai clinicians is suddenly going to be out of network,鈥 said Ateev Mehrotra, a hospitalist and telehealth researcher at Beth Israel Deaconess Medical Center.
It struck the doctors specializing in telehealth research whom 杨贵妃传媒視頻 Health News consulted as an unusual situation, especially since the doctor who provided the care was employed by the prestigious health system.
The doctor in question may have been in network for no insurers whatsoever: A review of the doctor鈥檚 Mount Sinai profile page 鈥 archived in November 2022 鈥 does not list any accepted insurance. (That鈥檚 in contrast to other doctors in the system.)
Lee, Mount Sinai鈥檚 spokesperson, said the doctor did take at least some insurance. When asked about the doctor鈥檚 webpage not showing any accepted plans, she responded the site 鈥渋nstructs patients to contact her office for the most up-to-date information.鈥

Attempting to solve this billing puzzle turned into a major league headache for Greenblatt. Deepening the mystery: After calling Mount Sinai鈥檚 billing department, she was told the case had been routed to disputes and marked as 鈥渦rgent.鈥
But the doctor鈥檚 office would seemingly not respond. 鈥淚n most other professions, you can鈥檛 just ignore a message for a year,鈥 she observed.
The bill would disappear on her patient portal, then come back again. Another call revealed a new twist: She was told by a staffer that she鈥檇 signed a form consenting to the out-of-network charge. But 鈥渨hen I asked to get a copy of the form I signed, she asked if she could fax it,鈥 Greenblatt said. Greenblatt said no. The billing department then asked whether they could put the form in her patient portal, for which Greenblatt gave permission. No form materialized.
When 杨贵妃传媒視頻 Health News asked Mount Sinai about the case in mid-October of this year, Lee, the system鈥檚 spokesperson, forwarded a copy of the three-page form 鈥 which Greenblatt didn鈥檛 remember signing. Lee said the forms are presented as part of the flow of the check-in process and 鈥渋ntended to be obvious to the patient as required by law.鈥 Lee said on average, a patient signs two to four forms before checking into the visit.
But, according to the time stamp on the forms, Greenblatt鈥檚 visit concluded before she signed. Lee said it is 鈥渘ot standard鈥 to sign forms after the visit has concluded, and said that once informed, patients 鈥渕ay contact the office and reschedule with an 鈥榠n-network provider.鈥欌
鈥淚f it was provided after the service was rendered, that is an exception and situational,鈥 she concluded.
The business with the forms 鈥 their timing and their obviousness 鈥 is potentially a vital distinction. In December 2020, Congress enacted the No Surprises Act, designed to crack down on so-called surprise medical bills that arise when patients think their care is covered by insurance but actually isn鈥檛. Allie Shalom, a lawyer with Foley & Lardner, said the law requires notice to be given to patients, and consent obtained in advance.
But the legislation provides an exception. It applies only to hospitals, hospital outpatient facilities, critical access hospitals, and ambulatory surgery centers. Greenblatt鈥檚 medical bill variously presents her visit as 鈥淥ffice/Outpatient鈥 or 鈥淓pisodic Telehealth,鈥 making it hard to 鈥渢ell the exact entity that provided the services,鈥 Shalom said.
That, in turn, makes its status under the No Surprises Act unclear. The rules apply when an out-of-network provider charges a patient for care received at an in-network facility. But Shalom couldn鈥檛 be sure what entity charged Greenblatt, and, therefore, whether that entity was in network.
As for Mount Sinai, Lee said asking for consent post-visit does not comply with the No Surprises Act, though she said the system needed more time to research whether Greenblatt was billed by the hospital or another entity.
The Resolution: Greenblatt鈥檚 bill is unpaid and unresolved.
The Takeaway: Unfortunately, patients need to be on guard to protect their wallets.
If you want to be a smart shopper, consider timing the length of your visit. The 鈥淏ill of the Month鈥 team regularly receives submissions from patients who were billed for a visit significantly longer than what took place. You shouldn鈥檛, for example, be charged for time sitting in a virtual waiting room.
Most important, even when you seek care at an in-network hospital, whose doctors are typically in network, always ask if a particular physician you鈥檝e not seen before is in your network. Many practices and hospitals offer providers in both categories (even if that logically feels unfair to patients). Providers are supposed to inform you that the care being rendered is out of network. But that 鈥渋nformed consent鈥 is often buried in a pile of consent forms that you auto-sign, in rapid fire. And the language is often a blanket statement, such as 鈥淚 understand that some of my care may be provided by caregivers not in my insurance network鈥 or 鈥淚 agree to pay for services not covered by my insurance.鈥
To a patient trying to quickly book care, that may not feel like 鈥渋nformed consent鈥 at all.
鈥淚t鈥檚 problematic to expect patients to read the fine print, especially when they feel unwell,鈥 Ganguli said.
