OncoEMR API
OncoEMR is Flatiron Health's cloud EHR purpose-built for community oncology, powering chemotherapy ordering with NCCN Order Templates, AJCC staging, molecular profiling, and practice operations for 4,700+ providers and 5M+ patient records. Its FHIR APIs sit behind a registration wall and additional fees, and other integrations run through Flatiron-managed HL7 interfaces restricted to an approved vendor list. An unofficial API lets you programmatically pull patients, appointments, treatment plans, orders, and claims—without FHIR fees, registration walls, or interface-vendor approvals.
What is OncoEMR?
OncoEMR is Flatiron Health's cloud-based electronic health record purpose-built for community oncology. Practices use it to run oncology-specific clinical workflows—chemotherapy ordering with built-in NCCN Order Templates, AJCC staging, and Flatiron Assist clinical decision support—alongside molecular profiling orders, financial tools like charge generation, HCC code notifications, and biosimilar drug substitution, and MIPS tracking for value-based care. The platform extends to the OncoAir mobile app and CareSpace patient portal, and today serves 4,700+ providers across 220+ community oncology practices, 1,600+ sites of care, and 5M+ patient records.
Core product areas include:
- Oncology EHR (chemotherapy ordering with NCCN Order Templates, AJCC staging, Flatiron Assist clinical decision support)
- Molecular profiling (order placement, status tracking, and results viewing)
- Financial and operations tools (charge generation, HCC code notifications, biosimilar drug substitution)
- Value-based care (MIPS tracking and reporting)
- Mobility and engagement (OncoAir mobile app, CareSpace patient portal)
Common data entities:
- Patients, Demographics, Staging records
- Treatment plans, Chemotherapy orders, Regimens, Dosing
- Appointments, Schedules, Visit notes
- Lab results, Molecular profiling orders and results
- Charges, Claims, HCC codes
The OncoEMR Integration Challenge
Community oncology practices run chemo ordering, staging, and practice operations on OncoEMR every day, but programmatic access to that data is tightly gated:
- Registration-walled FHIR docs: Flatiron's FHIR API documentation sits behind a registration-required portal, so you can't even scope an integration without vendor sign-off
- Paid, compliance-scoped FHIR: Flatiron's certification page notes that FHIR APIs may require additional fees—access is a per-tenant, fee-bearing add-on scoped to ONC certification requirements rather than a full integration surface
- HL7 through approved vendors only: Non-FHIR integrations run over Flatiron-managed HL7 interfaces restricted to an approved interface-vendor list, with partnered vendors (MaxMD, Surescripts, DrFirst) charging additional one-time and/or annual fees
- No self-serve surface: No public developer portal, SDKs, or webhooks—there is no way to simply sign up and start building
- Oncology data complexity: Regimens, chemo orders, dosing, staging, and molecular-profiling results carry oncology-specific structures that generic EHR integrations don't model
- PHI and compliance constraints: Cancer-patient data demands HIPAA-aligned access controls and audit trails
How Supergood Creates OncoEMR APIs
Supergood reverse-engineers OncoEMR's authenticated web workflows to deliver a resilient API layer for your practice—covering patients, treatment plans, scheduling, and billing without waiting on registration walls, FHIR fees, or the approved interface-vendor list.
- Handles practice credentials, MFA, and session continuity securely in a managed session
- Maintains sessions with automated refresh and change detection as Flatiron ships updates
- Normalizes responses across patients, treatment plans, orders, and claims so you integrate once and rely on consistent objects
- Aligns with HIPAA-conscious access controls, scoped tokens, and audit logging for PHI

Frequently asked questions
No. Supergood works with your existing OncoEMR credentials and authenticated sessions, so you don't need to pay FHIR access fees, register for the documentation portal, or join the approved interface-vendor list to reach your own data.
Yes. PHI flows through an encrypted credential vault with scoped tokens, HIPAA-aligned access controls, and full audit logging so patient and treatment data stays protected.
Yes. The API exposes treatment plans, regimens, and order status so you can track chemo ordering and molecular profiling programmatically alongside scheduling and billing data.
Yes. Supergood normalizes patients, schedules, and claims across sites of care so multi-site community oncology practices integrate once and get consistent objects everywhere.
Supergood continuously monitors OncoEMR releases and your practice configuration, adapting the adapter automatically so your integration keeps running through updates.
