Health Information Exchange (HIE) Overview
Welcome to the API documentation for the Health Information Exchange (HIE) system.
Health Information Exchange (HIE) is a national framework and infrastructure designed to enable the secure, authorized, and interoperable exchange of health data between different systems and facilities. Its primary goal is to move beyond the limitations of having many isolated Electronic Medical Records (EMRs) and Health Management Information Systems (HMIS) by providing a universal way of handling technical needs of these systems. HIE is built on foundational components like the Master Patient Index (MPI) for consistent patient identity, the Terminology Service (TS) to ensure systems "speak the same language" by standardizing codes (e.g., for diagnoses and medicines), and Consent Management to enforce privacy rules. HIE APIs allow developers to interact with these services, but they must adhere strictly to standardization principles: using registry IDs for identity, relying on coded data instead of free text, and always respecting patient consent.
If you’re new to Health Information Exchange or want to understand the motivation and architecture behind these APIs, see Understanding Health Information Exchange.
Key HIE APIs
The HIE platform is built on several core APIs. Below are the primary APIs you’ll interact with, each with a dedicated introduction page for deeper exploration:
-
Authentication API:
Securely authenticate users and systems, obtain access tokens, and enforce authorization for all HIE API calls. -
Claims & Preauths API:
Submit, edit, track, and manage healthcare claims and preauthorization requests, supporting the full claims lifecycle from eligibility to remittance. -
Consent Services API:
Manage beneficiary consent using OTP or biometrics, ensuring privacy, compliance, and explicit authorization for data access and sharing. -
Registries API:
Search and validate patients, professionals, and facilities using standardized identifiers, supporting accurate and interoperable healthcare transactions.
Why Use the HIE APIs?
- Interoperability: Standardized APIs ensure seamless data exchange between disparate systems.
- Data Integrity: Centralized registries prevent duplication and errors, supporting accurate reporting and analytics.
- Compliance: Built-in consent and audit mechanisms help you meet regulatory requirements.
- Efficiency: Automate workflows, reduce manual errors, and accelerate care delivery and reimbursement.
