Nationally from November to December, COVID-19 rose from the fifth most-frequent telehealth diagnosis to the third. In the Northeast — the epicenter of December’s coronavirus surge — it rose from fifth to second place.

Mental health diagnoses remained the number one diagnosis overall and in all U.S. regions in December. However, its percentage share of telehealth claims fell. That drop was particularly acute in the South, which was the only region to see mental health diagnoses fall to fewer than 50% of all telehealth claim lines.

Experts say mental health is a particular growth area for virtual care, as the pandemic has seriously exacerbated conditions like depression and anxiety while accelerating the creation and use of telemental options. According to CB Insights, global funding for mental health tech startups reached a record $5.5 billion in 2021, up almost 140% from the year prior.

Meanwhile, acute respiratory diseases and infections rose everywhere in percentage share of telehealth claim lines. Hypertension joined the top five telehealth diagnoses in the South and joint and soft tissue issues joined in the Northeast.

Market watchers are waiting to see where demand for telehealth stabilizes once the brunt of COVID-19 is behind the U.S. Projections vary, though the majority agree virtual care use will persist at higher levels than before the pandemic, and future access and use depends on a slew of factors, including how many pandemic-era regulatory flexibilities Washington allows once the COVID-19 public health emergency expires.

That’s currently slated to run out in April, though it’s likely to be extended for another 90 days. In the meantime, legislators are debating what shape future telehealth regulations should take, though telehealth proponents are optimistic due to broad bipartisan support for greater access on the Hill.
