What is ABDM (Ayushman Bharat Digital Mission)?
The Ayushman Bharat Digital Mission (ABDM) is the Government of India’s national initiative to build a unified digital health ecosystem for the country. It was originally piloted and announced as the National Digital Health Mission (NDHM) in 2020, then rolled out nationally and rebranded to ABDM. Both names still appear in official documentation and older tooling — they refer to the same underlying mission.
Core building blocks
ABDM isn’t a single app — it’s a set of interoperable registries and identifiers that health-tech products (like lab systems, hospital EHRs, and pharmacy software) are expected to integrate with:
- ABHA (Ayushman Bharat Health Account) — a voluntary, portable health ID for individuals, used to link a person’s health records across providers.
- Healthcare Professionals Registry (HPR) — a verified registry of doctors and other clinical staff.
- Health Facility Registry (HFR) — a verified registry of clinics, hospitals, labs, and pharmacies.
- Health Information Exchange & Consent Manager framework — the consent-driven mechanism by which health records move between providers, rather than being centrally stored by the government.
Why FHIR matters here
For health records to actually move between different vendors’ software, everyone needs to agree on a common data format. ABDM adopted FHIR R4 (Fast Healthcare Interoperability Resources) as that common format, with India-specific profiles and extensions published by NRCeS (National Resource Centre for EHR Standards) as the ABDM/NDHM FHIR Implementation Guide. That’s the guide this site’s validator checks resources against.
If you’re building software that needs to exchange lab reports, prescriptions, or discharge summaries in India, ABDM compliance and FHIR R4 conformance are effectively the same underlying requirement.
See the FHIR R4 Implementation Guide for India article for what that looks like in practice.
