If a patient walked out of your clinic today with a referral to a nephrologist across town, what would travel with them? For most Indian practices, the honest answer is a printout or a WhatsApp PDF. That answer tells you more about the EMR vs EHR question than any vendor brochure.
The textbook definitions are simple. An electronic medical record (EMR) is your clinic's chart in digital form, built for use inside your own practice. An electronic health record (EHR) is built to be read by other systems too: the lab, the hospital, the next doctor. In practice, the line between them depends on how the data is stored and whether other software can understand it.
What India's standards say
India has had official guidance on this for over a decade. The Ministry of Health and Family Welfare first notified Electronic Health Record Standards for India in 2013 and published a revised set in December 2016. The National Resource Centre for EHR Standards (NRCeS) still hosts them. The 2016 standards name SNOMED CT for clinical terms, LOINC for lab tests and observations, and the WHO classification family, including ICD-10, for diagnoses. You will see some vendors and blogs cite ICD-11. The 2016 document doesn't mention it.
The standards also name the plumbing for moving records around (HL7 v2.8.2, ISO 13606, openEHR, DICOM for images). They say health records should be preserved for the patient's lifetime, which surprises many clinics that shred paper files after a few years.
A newer layer now matters more for day-to-day work. For record exchange under the Ayushman Bharat Digital Mission (ABDM), NRCeS publishes a FHIR R4 implementation guide with record types such as OPConsultRecord, PrescriptionRecord and DiagnosticReportRecord. If you want records to move through ABDM, that is the format your software has to produce.
The part most comparisons get wrong
A lot of writing on this topic says a basic EMR "can't do ABDM." That overstates it. The ABDM FHIR guide includes a profile called HealthDocumentRecord, designed for unstructured historical records. A scanned discharge summary or a PDF prescription can be shared through ABDM if the software wraps it correctly.
So an EMR can take part in ABDM. What changes is how useful the shared record is. A PDF lands on the other side as a picture of information. A coded record lands as data: the receiving system knows the "HbA1c 8.2%" is a lab value, can plot it next to last year's result, and can flag a drug interaction against a coded diagnosis. That difference is what makes an EHR more valuable.
Also keep facility registration separate from record format. ABDM's own verifier guidance for the Health Facility Registry says HFR does not set standards for how facilities operate. Registering your clinic there doesn't check your records at all.
Which one do you need?
Think about where your records go, not what the software calls itself. A solo practice with few referrals and no ABDM plans is fine on a well-organised EMR, as long as everything can be exported if you switch vendors. Once you refer out or receive referrals every week, coded records start paying off, because a referral letter the specialist's system can read saves both sides retyping. Multiple locations or a group practice need shared, structured records across branches, or each branch ends up with its own version of the patient.
Sharing records with patients' ABHA-linked apps is a separate test. For that you need software that has completed ABDM integration as a health information provider (the side that sends records out), so get that status confirmed in writing. Whether it calls itself an EMR or an EHR tells you nothing.
Questions to put to a vendor
Vendors use both labels loosely, so ask about specifics:
- Which terminology do you code diagnoses and lab results to? (Listen for SNOMED CT, LOINC, ICD-10.)
- Is your product integrated with ABDM, and at which stage? Can I see a record being shared to an ABHA app in a live demo?
- If I leave, what format do I get my data back in: structured files or a folder of PDFs?
- What happens to my old notes if I upgrade?
A vendor who answers these clearly has probably built what they're selling. If they send you back to a features page, their product is probably a basic EMR.
Where ExaHealth stands on these questions
ExaHealth is an ABDM-certified PHR and Health Locker. When a patient's ABHA is linked and the patient gives consent, the clinic can bring in records from elsewhere and send its own records out, which is the ABHA sharing test described above. For prescriptions, the doctor selects each medicine instead of typing it as free text, and the patient gets a printable PDF on WhatsApp. ExaHealth records who opened each file and when, and data is encrypted and hosted in India on AWS Mumbai. The four questions above apply to us too, and seeing a record reach an ABHA app during the demo is a fair request.
Moving from an EMR to structured records
If you are already on a free-text EMR, don't try to convert ten years of notes into coded data. It takes a long time and mistakes creep in. Machine-assisted coding of old notes still needs a clinician to check each one.
A cleaner approach is to freeze the old records as a searchable, read-only archive (and, where your software supports it, make them shareable as documents through ABDM), then start coding from a fixed date. Take a hypothetical physician in Coimbatore. She picks 1 April, codes every new diagnosis and lab order from that day, and leaves older notes as documents. Within a year or two, most of her active patients have a structured history, because the people she sees often are the ones who come back often.
A quick test you can run today
Pick a patient and try to send their last visit to another clinic's system electronically. If the only way is a PDF or a printout, you are running an EMR, whatever the login screen says. If the other system can pull in the diagnosis, medicines and lab values as separate fields, you have an EHR. Both are legitimate choices. You just need to know which one you are paying for.

Frequently Asked Questions
What is the practical difference between an EMR and an EHR?
An EMR is a digital chart built for use inside one practice. An EHR stores information in coded, standard formats so another doctor's or lab's system can read it as data, not just view it as a document.
Which coding standards does India recommend for health records?
The EHR Standards for India (revised December 2016) recommend SNOMED CT for clinical terms, LOINC for lab tests and observations, and WHO classifications such as ICD-10. For exchange through ABDM, NRCeS publishes FHIR R4 profiles that software must follow.
Can a clinic using a basic EMR still participate in ABDM?
Yes, if the software is ABDM-integrated. ABDM's FHIR guide includes a profile for unstructured health documents, so PDFs and scanned records can be shared. Structured records are more useful to the receiving doctor, but they aren't a precondition.
Does registering on the ABDM Health Facility Registry mean my records are ABDM-ready?
No. HFR registration gives your facility an ID in the national registry. It doesn't check or change how your software stores patient records. Record sharing depends on your software's ABDM integration.
How long should electronic health records be kept?
The 2016 EHR Standards say records should be preserved for the person's lifetime. Check your state rules and any professional regulations that apply as well.
Should I convert my old free-text notes into coded records when I switch systems?
Usually not. Keep the old notes as a read-only archive and start structured records from a fixed date. Your frequent patients will have coded histories fairly quickly.
