Telemedicine in the coronavirus pandemic moved from a niche service to a default way of seeing patients within weeks in 2020. Emergency rules from Medicare, HHS, the DEA and the states removed barriers that had held virtual care back for years, and providers adopted whatever tools they could get working.
This guide looks back at that period as a record for builders: which rules changed, what platforms had to build in a hurry, what happened when the emergency ended in 2023, and which lessons still shape telemedicine software design.
What did telemedicine look like during the coronavirus pandemic?
Replacing a telemedicine setup built in a hurry?
Agnotic builds telemedicine platforms that replace emergency-era tools with integrated, maintainable services.
Telemedicine during the coronavirus pandemic was emergency care delivery: clinicians saw patients at home by video or phone under temporary federal and state flexibilities, often on consumer tools with little EHR integration. The COVID-19 public health emergency, declared in January 2020, ended on 11 May 2023, taking several of those flexibilities with it.
For engineers, the period was a stress test. Systems built for a few virtual visits a day suddenly carried a large share of outpatient care, and every weakness in scheduling, identity, billing and documentation showed up at once.
Security teams felt it too. Remote work for clinicians and staff arrived at the same time as remote care for patients, so home networks, personal devices and new video accounts all joined the attack surface within weeks, while phishing campaigns used pandemic themes.
Which emergency rules made the shift possible?
Four kinds of emergency rule made the shift possible, each from a different owner. Together they removed limits on where patients could be, which tools clinicians could use, how controlled substances could be prescribed and who could practice across state lines.
- Medicare coverage: Waivers and later legislation let patients receive Medicare telehealth at home and outside rural areas, added services to the telehealth list and allowed some services by audio only.
- HIPAA enforcement: In March 2020, HHS OCR said it would not penalize providers for good-faith use of everyday non-public-facing video and chat tools, even without a business associate agreement.
- Controlled-substance prescribing: The DEA allowed prescribing by telemedicine without a prior in-person evaluation during the emergency.
- State licensure: Many states temporarily let out-of-state clinicians treat their residents, through emergency orders with their own conditions and end dates.
Each flexibility had its own legal basis and its own end date, which mattered later. Teams that treated "the pandemic rules" as one switch found that they expired on different days.
Payers outside Medicare moved on their own timelines too. Medicaid programs and commercial plans issued their own telehealth policies, some temporary and some permanent, and claim rules differed by plan. Billing teams kept running lists of who paid for what, which later became the payer rules that platforms now hold as configuration.
What did platforms have to build in a hurry?
Platforms had to build scheduling, virtual waiting rooms, consent capture, location capture and claim coding for telehealth at speed, often bolted onto systems designed for in-person care. Many organizations ran video in one tool, scheduling in another and documentation in the EHR, joined by staff copying data between them.
- Visit links: Systems to create, send and resend video links, often by email or text from a staff member's screen.
- Waiting rooms: Virtual queues so clinicians could see who had joined and admit them in turn.
- Phone fallback: Ways to switch a failed video visit to a phone call and record that it happened.
- Coding changes: New place of service and modifier rules applied to claims as CMS guidance evolved.
- Consent capture: Verbal or electronic consent for telehealth recorded in notes or forms.
- Device loans: Tablets and hotspots sent to patients without devices or connections.
Speed was the right priority at the time. The cost came later, when the workarounds had to be maintained, secured and reconciled with rules that kept changing.
How did EHR integration hold up?
EHR integration was the weakest link for many services. Video tools that were not connected to the EHR had no access to the schedule, the patient list or the chart, so staff created visits by hand, pasted links into reminders and typed visit details into notes afterward.
That gap caused three kinds of error. Patients received links for the wrong time or the wrong clinician. Notes were filed late or against the wrong encounter. And claims went out without the telehealth place of service or modifier, because nothing in the visit record said it had been virtual.
Integrated setups avoided most of this. Where the visit was created from the EHR appointment, the link, the encounter and the claim all carried the same visit identifier, and the modality was recorded automatically. The lesson was that the visit record, not the video session, has to be the source of truth.
Interfaces did not need to be new. Scheduling messages, ADT events and document filing over HL7 v2 carried most of the integrated workflows, with FHIR used where the EHR exposed it.
How did the end of the emergency change things?
The end of the emergency changed the compliance baseline overnight for some rules and left others in place. OCR's relief for everyday video tools ended on the same day, 11 May 2023, and after a 90-day transition that closed on 9 August 2023, providers needed tools covered by business associate agreements and full HIPAA safeguards.
Other flexibilities outlived the emergency. Congress extended the Medicare telehealth flexibilities several times, and the Consolidated Appropriations Act, 2026 now extends them through 31 December 2027. The DEA and HHS extended the controlled-substance flexibilities by temporary rule, most recently through 31 December 2026.
State licensure waivers mostly ended with state emergencies, on dates set by each state. Clinicians who had been seeing patients across state lines needed full licenses, compact privileges or telehealth registrations to continue.
The pattern for builders was clear: rules that had arrived together left separately, on different schedules, and software had to track each one.
Patients noticed the change too. Services that had relied on everyday video apps had to move patients to new links, new apps or portal logins, and some patients dropped out at that step. Clear notice, a test visit and a phone fallback made the switch easier.
Which pandemic-era models stayed?
Several care models that grew during the pandemic stayed after it, because patients and clinicians found them useful and coverage continued. They are now standard features rather than emergency measures.
- Home video visits: Follow-ups, medication reviews and behavioral health visits from the patient's home.
- Audio-only visits: Phone visits for patients who cannot or will not use video, within payer rules.
- Remote monitoring: Device readings reviewed between visits for chronic conditions.
- Virtual triage: Nurse or clinician screening by phone or video before an in-person visit.
- Hybrid scheduling: Booking systems that offer in-person and virtual slots side by side for the same clinician.
Each model now runs under its own rules for coverage, documentation and consent. A platform that offers them needs those rules as data, not as habits carried over from 2020.
Clinician habits stayed as well. Many clinicians now expect to review device data, photos and questionnaires before a virtual visit, and to switch a visit between video and phone without a new booking. Those expectations are product requirements for any platform built today.
Which pandemic shortcuts became technical debt?
The shortcuts that became technical debt were the ones that kept running after the reason for them ended. These are the failure points worth checking in any telemedicine setup that dates from the emergency.
- Uncovered tools: Video or chat tools still in use without a business associate agreement after the transition period.
- Manual re-keying: Visit details copied by staff from the video tool into the EHR, with errors and delays.
- Shared accounts: Department-wide logins on video platforms, with no audit trail of who saw which patient.
- Hard-coded coding: Place of service and modifier rules written into code rather than configuration, so each change needed a release.
- Stale licensure data: Clinician state authorities tracked in spreadsheets, without expiry alerts after waivers ended.
- Orphaned devices: Loaned tablets and hotspots with no device management or return process.
What the pandemic record means for builders today
The pandemic record turns into a short set of design rules for telemedicine software. Each lesson maps to a feature a platform should have.
- Rules end separately: Store every coverage, prescribing and licensure rule with its own start date, end date and source.
- Tools must be covered: Keep a vendor register and require a business associate agreement before any tool handles PHI.
- Integration beats re-keying: Create visits from EHR appointments and file notes back automatically.
- Fallbacks are features: Build audio-only switching and rebooking into the visit flow, with the reason recorded.
- Location drives everything: Capture the patient's location at every visit for routing, licensure and coding.
- Test the calendar: Run the platform with the clock moved past each known deadline before it arrives.
These rules matter again now, because the current federal dates at the end of 2026 and 2027 could create the same kind of transition. Platforms built with dated rules can meet either outcome without an emergency rebuild.
