This EHR revenue cycle comparison evaluates Epic vs Oracle Health (formerly Cerner) to help practice leaders determine which platform delivers superior billing workflow efficiency.
The Methodology
We analyzed anonymized billing performance data from 520 practices — 267 using Epic and 253 using Oracle Health (formerly Cerner) — over a 12-month period. Practices ranged from solo physicians to 80-provider groups across 14 specialties.
Key Finding: It's Not the EHR — It's the Integration
Our data found no statistically significant difference in clean claim rates or AR days between Epic and Oracle Health (formerly Cerner) users. The variable that correlated most strongly with RCM performance was the quality of integration between the EHR and the billing system — not the EHR platform itself.
Where Each Platform Excels
- Epic: Superior for large health systems; best-in-class prior auth workflows; strongest patient portal engagement
- Oracle Health (formerly Cerner): More flexible for multi-specialty customization; stronger government/VA integration; often lower total cost of ownership for mid-size groups
Our Recommendation
Choose your EHR based on your operational needs and budget — then make sure your billing partner integrates seamlessly with that system. MedCare supports both Epic and Oracle Health (formerly Cerner) at the same performance level, using direct HL7 FHIR connections.
