Overview
Since the second half of 2026, several regional data groups and operators, together with insurers, medical-insurance and health authorities, have explored compliant circulation of medical and insurance data to link basic medical insurance with commercial health insurance. China Business Journal reports the path splits into two directions: pre-underwriting risk control via privacy computing and trusted data spaces outputting risk scores, and post-discharge one-stop direct settlement linking insurers, hospitals and commercial payers.
Examples are live: Chuzhou completed Anhui’s first marketized public-data authorization transaction, building an underwriting risk-scoring API on data for over 4 million residents, strictly keeping raw data in-domain and usable but invisible, outputting only scores across 17 dimensions. Wuxi’s data group upgraded underwriting and claims products from reports to standard API services.
Background & Interpretation
1. Regulatory and Industry Context
Traditional underwriting relied on self-disclosed health and manual chart checks; claims required upfront payment then paperwork—slow, costly, fraud-prone. Under the multi-tier medical-security system, medical-insurance data synergy is the key link, and public-data authorization pilots offer a marketizable path.
2. Core Drivers and Underlying Mechanism
Privacy computing, trusted data spaces and data sandboxes let medical data model and verify while raw data stays in-domain. Underwriting APIs, after electronic authorization, output only risk scores and tiers; post-discharge direct settlement connects three parties for one-stop claims, compressing cycles.
3. Market Structure and Industry Chain Impact
The new model replaces insurers’ point-to-point hospital links and duplicated channels with a neutral data operator outputting standardized, reusable risk and claims capability. This lowers compliant acquisition and risk cost for insurers and opens a data-monetization scenario for data groups, driving medical-payer-data tri-party synergy.
Implications & Outlook
If scaled, commercial health insurance’s risk and service logic may be rewritten—from ex-post payout to ex-ante risk control plus in-process direct claims. Watch local public-data legislation and standards, privacy-computing penetration, and the hospital and claim coverage of one-stop settlement.
Takeaways for Industry Participants
For insurers: use public-data APIs to raise underwriting precision and anti-fraud at low cost, refining health-insurance pricing. For data groups and platforms: build compliant, auditable data products as neutral infrastructure. For hospitals and payers: standardize settlement links to unlock data-element value.
