Practice Fusion API
Practice Fusion is a cloud-based EHR and medical billing platform built for independent practices, covering charting, e-prescribing, billing services, labs, and imaging. An unofficial API lets you programmatically pull patients, encounters, appointments, medications, conditions, lab results, and imaging orders—and push updates like new charts, prescriptions, and billing data—without waiting on FHIR app registration or partner marketplace approval.
What is Practice Fusion?
Practice Fusion is a cloud-based EHR and medical billing platform designed for independent medical practices, part of the Veradigm network. Practices use Practice Fusion to chart and document patient care, send electronic prescriptions through ePrescribe, manage revenue through Billing Services, and connect to labs and imaging providers—all through a connected platform that more than 600 partner companies integrate with.
Core product areas include:
- Electronic Health Record (charting, clinical documentation, patient care)
- ePrescribe (electronic prescribing, including controlled substances)
- Billing Services (practice revenue cycle and medical billing)
- Labs API integration (orders and results with hospital and health system labs)
- Imaging API integration (radiology orders and studies)
- FHIR R4 API and ONC-Certified EHR API for third-party app developers
Common data entities:
- Patients, Practitioners, RelatedPersons, Coverage
- Encounters, EpisodesOfCare, Appointments, CarePlans, CareTeams
- MedicationRequests, MedicationDispenses, AllergyIntolerances, Immunizations
- Conditions, Observations, Procedures, DiagnosticReports, ServiceRequests
- Lab orders and results, ImagingStudies, Specimens, DocumentReferences
The Practice Fusion Integration Challenge
Independent practices run daily clinical and billing work on Practice Fusion, but turning that portal-driven workflow into reliable API automation is harder than it looks:
- Developer registration gates: third-party FHIR apps must register with Practice Fusion and obtain client credentials before they can call the service base URL
- Marketplace and partner approval: Labs and Imaging API access flows through partner integration agreements rather than self-serve signup
- OAuth 2.0 and PKCE complexity: authorization-code, PKCE (S256), and client-credentials flows each require careful token, refresh, and introspection handling
- FHIR-only read surface: the certified API is read-oriented and US Core-scoped, so many practice and billing actions still live behind the web portal
- ONC-Certified EHR API fees: programmatic access carries associated fees and EHI export requirements that vary by use case
- Billing and scheduling gaps: revenue-cycle, scheduling, and patient-engagement data aren't fully exposed through the public FHIR resources
How Supergood Creates Practice Fusion APIs
Supergood combines authenticated browser flows with Practice Fusion's FHIR R4 catalogue to deliver a resilient, unified API layer for your practice—covering both the certified FHIR surface and the portal-only workflows that sit outside it.
- Handles username/password login and MFA securely, plus OAuth 2.0 / PKCE token exchange where the FHIR API is available
- Maintains session continuity with automated refresh and change detection
- Normalizes responses across patients, encounters, medications, conditions, lab results, and imaging so you integrate once against consistent objects
- Aligns with US Core / FHIR R4 semantics while filling the gaps for scheduling and billing data that the public API doesn't expose

API Endpoints
Authentication
/authenticateAuthenticate to a Practice Fusion practice using credentials or OAuth 2.0 / PKCE and obtain a session token for downstream calls.
Patient Operations
/patientsList and search patient (FHIR Patient) records with filters for name, identifier, demographics, and active status.
Scheduling
/appointmentsRetrieve appointments and encounters with filters for provider, location, status, and date range.
Clinical
/encountersPull encounter records including conditions, observations, procedures, and care team for a given patient.
Prescribing
/create_prescriptionSubmit a MedicationRequest (e-prescription) for a patient through the ePrescribe workflow.
Diagnostics
/lab_resultsRetrieve lab orders, results, and diagnostic reports surfaced through the Labs and Imaging integrations.
Use Cases
Sync patient and clinical data into your stack
- Pull patients, encounters, conditions, and observations into a single warehouse or analytics platform - Stream medication, allergy, and immunization records to care-coordination tools - Reconcile patient demographics and coverage across systems for a unified record
Automate e-prescribing and medication workflows
- Submit MedicationRequests into ePrescribe without portal clicks - Pull medication history and dispense records for reconciliation - Surface refill and renewal events to downstream pharmacy and patient apps
Integrate labs and imaging results
- Receive lab orders and results from the Labs API into your LIS or EHR - Route imaging orders and studies through the Imaging API to radiology partners - Attach diagnostic reports and document references to the right encounter
Connect billing and scheduling to external systems
- Sync appointment and encounter data into scheduling and patient-engagement tools - Push charge and billing data to revenue-cycle and accounting systems - Trigger patient reminders and intake workflows when appointments change

Frequently asked questions
No. Supergood works with your existing Practice Fusion credentials and authenticated sessions. Where you already have a registered FHIR app and client credentials, we use them; where you don't, we operate against the same authenticated surfaces so you don't have to wait on registration or marketplace approval.
Yes. The ONC-Certified FHIR API is read-oriented and US Core-scoped. Supergood supplements it by working against the authenticated portal so you can reach scheduling, billing, and patient-engagement data that the public FHIR resources don't expose.
Yes. In addition to reads, Supergood can push updates such as MedicationRequests through ePrescribe and clinical documentation, with idempotency and retry handling to keep writes safe.
Lab orders, results, and imaging studies are exposed through the same normalized API surface, mapping the Labs and Imaging partner integrations alongside FHIR clinical resources so diagnostic data sits with the right patient and encounter.
Supergood uses an encrypted credential vault, scoped access tokens, audit logging, and HIPAA-aligned controls. Access is limited to the entitlements of the authenticated account you connect.
