Why does switching from Epic MyChart to Athena patient portal lose 80 percent of your medical history?
When a patient's PCP switches EHRs or moves health systems, the new portal imports a CCDA that drops prior med trial failures, family history annotations, and free-text allergy notes, so the patient re-types 5 years of history into intake forms.

What is the “Why does switching from Epic MyChart to Athena patient portal lose 80 percent of your medical history?” problem in 2026?
When a patient's PCP switches EHRs or moves health systems, the new portal imports a CCDA that drops prior med trial failures, family history annotations, and free-text allergy notes, so the patient re-types 5 years of history into intake forms.
Who has this problem?
Chronic-condition patient (autoimmune, mental health, chronic pain) switching providers.
Evidence this problem is real
“My rheum left the Sutter system and moved to a private practice on Athena. The CCDA they sent had my labs but not the notes about which biologics already failed me. New doc wanted to put me back on Humira which already stopped working in 2022.”
Existing players in this space
- Apple Health Records — Aggregates portals but does not reconcile narrative notes.
- Picnic Health — Human-assisted, slow, expensive.
- Particle Health — B2B network, not patient-facing.
What existing players are missing
A multimodal agent that ingests CCDA, scanned chart pages, MyChart screenshots, and patient narrative, then produces a doctor-readable one-page handoff with prior med failures, dose history, and active problem reasoning intact.
