Thailand is connecting treatment records from nearly 20,000 service points to its national claims system, with AI checking outpatient claims before payment. For hospitals, clinics and pharmacies, the record has become the claim.
Thailand has quietly built one of the region's most connected health data systems. A national exchange, a public health cloud and a growing set of patient-facing apps now link hospitals, clinics and pharmacies across the country. In 2026, that exchange took on a new role: supporting how claims are checked and paid.
For providers, this is a meaningful shift. The same record a clinician relies on is now read by a payer's AI before payment, and by the patient on their phone. Data that was good enough inside one facility now has to hold up in three places at once.
This guide explains what has changed, why it matters, and what providers should fix first. It draws on our experience at Jonda Health, where our work is turning health records from many different sources, in more than ten languages, into structured, standardised information that clinicians and systems can actually use.
Figure 1. Thailand: connecting health data nationally.
In November 2025, the Ministry of Public Health's special committee on the national digital health system approved measures to integrate public health information systems, link service data between Ministry facilities and the Bangkok Metropolitan Administration through Health Link, Mor Prom and the Public Health Cloud, connect health data with the Ministry of Labour, and establish a framework for a new Digital Health Act. The Public Health Minister described that Act as a foundational law for secure, interoperable, innovation-ready digital health governance (Healthcare IT News).
On 27 April 2026, the National Health Security Office (NHSO) and the Big Data Institute agreed, with the Digital Government Development Agency as witness, to upgrade Health Link and integrate it with NHSO's claims database. The upgrade connects treatment information from more than 10,000 NHSO service units and around 8,500 clinics and pharmacies, introduces an AI system for pre-audit verification of outpatient claims, gives patients access to their medical history through the Thang Rath app, and pilots electronic referral in Bangkok. NHSO's leadership describes the aim as faster, more complete access to patient histories, less duplication, and greater transparency and payment efficiency (Thairath).
The practical effect is that a provider's record now has several readers, each with different needs.
Figure 2. One record, many readers.
A clinician at another facility needs a history they can read quickly. An AI pre-audit needs data that is consistent enough to check against rules and patterns. A patient needs information that makes sense to them. A laboratory result with a local test name, a medicine recorded under several names, or a patient registered slightly differently in two systems can cause friction in all three. We explore the claims side of this in more depth in Clean Data, Faster Claims, drawing on a similar shift in the Philippines.
Thailand's Personal Data Protection Committee has become steadily more active. By 2025 it had issued administrative fines totalling more than THB 21.5 million, with healthcare among the sectors affected. One case stands out for providers: a large private hospital was fined THB 1,210,000 after more than 1,000 patient records were exposed through a flaw in its document destruction process, having failed to oversee the contractor responsible. The contractor was also fined (Herbert Smith Freehills Kramer).
The lesson is practical. Records work, whether destroying paper, digitising history or cleaning data, often involves third parties. The hospital remains responsible for how they handle patient data, so any partner's security, processing location and oversight should be agreed before work begins.
In the records we work with across the region, the same patterns appear again and again. For Thai providers, we would start with these.
None of this reflects poor practice. It is how records build up across busy facilities and systems. AI can help with much of this work at speed, and we use it extensively ourselves, but in a clinical and financial setting it needs clinical review and quality checks behind it. That is why we argue that healthcare AI will not work without trusted data infrastructure.
At Jonda Health, we have spent years working with health records across languages, formats and health systems. Depending on where your organisation is today, there are three ways we can help.
Health Link is Thailand's national health information exchange, launched in 2023 and rolled out nationally with the Public Health Cloud in 2024. It allows treatment information to be shared across facilities, and following an April 2026 agreement it connects nearly 20,000 service points, including NHSO service units, clinics and pharmacies.
On 27 April 2026, the National Health Security Office and the Big Data Institute agreed, with the Digital Government Development Agency as witness, to upgrade Health Link and integrate it with NHSO's claims database. The upgrade includes an AI system for pre-audit verification of outpatient service claims, patient access to medical history through the Thang Rath app, and an e-Referral system piloted in Bangkok.
In November 2025, a Ministry of Public Health committee approved a framework for drafting a new Digital Health Act, which the Public Health Minister described as a foundational law for secure, interoperable, innovation-ready digital health governance. It has not yet been enacted.
Thailand's Personal Data Protection Committee has become more active in enforcement. In 2025, a large private hospital was fined THB 1,210,000 after more than 1,000 patient records were exposed through a flaw in its document destruction process, and its contractor was also fined.
Start with the data that travels most: patient identity, diagnoses and procedures, laboratory results and medicines. Check that they are recorded consistently, that documents are structured where possible, and that contractors handling records are properly overseen.
