Critically, Medicare raised fees for virtual visits to match those for in-office exams, a move followed by state Medicaid programs and many commercial insurers.
The surge was explosive. While fewer than 1% of primary care visits in Medicare occurred virtually in January 2020, by April nearly half did, according to data compiled by the Medicare Payment Advisory Commission.
At UnitedHealth Group, the nation's largest health insurer, the number of covered telehealth visits increased nearly thirtyfold, rising from 1.2 million visits in 2019 to 34 million last year. Other insurers reported as much as an eightyfold increase.
“Very quickly, it became clear that we could deliver very good care to our patients via televisit," said Dr. Manish Naik, chief medical information officer at Austin Regional Clinic in central Texas.
The medical group not only helped its primary care physicians pivot to telehealth, but it also built a virtual urgent care system that allows patients to connect by video with on-call doctors 24 hours a day, a model used by large medical systems such as Kaiser Permanente.
Other systems are moving beyond televisits to expand use of remote monitoring tools in people's homes that track vital signs of patients with chronic illnesses such as diabetes.
Perhaps nowhere has telehealth proved more transformational than in mental health services and treatment for patients addicted to drugs.
“Telehealth has been a godsend," said Ellen Bemis, chief executive of AMHC, a network of behavioral health clinics in rural northern Maine. Bemis said the clinics are already seeing patients adhere better to their medications as they remain in better contact virtually.
“I hope we never go back," she said.
In Alaska, health officials feel the same way. “What we've seen through covid was amazing," said state Medicaid director Albert Wall, noting a major decline in patients missing appointments.
Whether these changes endure depends largely on Congress and the Biden administration, which hasn't indicated whether it will make permanent the looser telehealth rules rolled out last year. The rules will sunset when the public health emergency ends, likely at the end of this year.
The uncertainty is fueling an urgent effort by physicians, hospitals, patient advocates and others to persuade government officials not to reimpose the strict limitations.
Democrats and Republicans in Congress have introduced bills to cement the changes. In statehouses, advocates for expanding telehealth have introduced more than 650 bills, according to the Alliance for Connected Care, a telehealth lobbying coalition.
“We've seen the potential of telehealth," said Dr. Christopher Crow, chief executive of Texas-based Catalyst Health Network, which helps primary care physicians manage their practices. “Now, we have to make sure we realize it before everyone starts shifting back to the exam rooms."
Major physician groups are pushing to maintain equal reimbursement for telehealth and in-person visits.
Dr. Susan Bailey, president of the American Medical Association, said Medicare should continue to allow patients to receive virtual care in their homes and in all areas of the country, not just rural areas.
The association is also pushing for Medicare to keep reimbursing doctors for consulting with patients by phone, a move Bailey said would ensure that patients without broadband internet service aren't left behind.
The push for more billable services has raised concerns about fraud, especially as physicians and hospitals develop more efficient systems to see patients remotely. “Overuse is absolutely a concern," said Dr. Von Nguyen, chief medical officer at Blue Cross Blue Shield of North Carolina. “Once these systems are in place, I suspect, the risk will be greater."
Nevertheless, many insurers and state Medicaid programs, two groups that typically look more skeptically at services that can drive up costs, are backing telehealth expansion.
And despite initial fraud concerns, nearly a dozen Medicaid and insurance industry officials interviewed for this article noted that thus far they've seen little evidence of widespread misuse.
“There is fraud in traditional medical care, too," said Dr. Donna O'Shea, a senior executive at UnitedHealth Group.
Several insurance officials said telehealth could ultimately save money by routing some medical care from high-cost doctors' offices and hospitals to lower-priced virtual visits, particularly for urgent care.
And some insurance companies — including Harvard Pilgrim Health Care in New England and Priority Health in Michigan — are marketing health plans with lower premiums that steer patients to virtual care.
“We see this being a long-term change," said Dr. Michael Sherman, Harvard Pilgrim's chief medical officer.
Sherman said the health plan is even exploring whether to help low-income patients get internet access to expand telehealth further. “We have proven to ourselves that this works," he said.
