ABDM & Compliance

Understanding ABDM and ABHA Integration for Healthcare Institutions in India

By Healthcare Compliance Architect • October 2026 • 8 min read

The Ayushman Bharat Digital Mission (ABDM), initiated by the National Health Authority (NHA), is creating an open digital health ecosystem for India. Understanding how this framework interacts with hospital software is crucial for hospital leadership.

What Is an ABHA Number and ABHA Address?

Ayushman Bharat Health Account (ABHA) is a 14-digit identifier that enables Indian citizens to link, store, and share their health records digitally with healthcare providers upon consent.

Understanding the ABDM Milestones (M1, M2, M3)

The ABDM integration architecture is categorized into three key milestone capabilities:

  • Milestone 1 (M1): ABHA creation, verification (via Aadhaar OTP or mobile OTP), and linking ABHA IDs to the hospital’s patient master index.
  • Milestone 2 (M2): Health Information Provider (HIP) workflows—digitizing clinical consultations, lab tests, and discharge summaries, and sharing them through the ABDM gateway upon patient consent.
  • Milestone 3 (M3): Health Information User (HIU) workflows—requesting and viewing external medical history with patient consent.
