Artificial intelligence is becoming a bigger part of medical underwriting in the protection market. While AI can sound impersonal, its purpose is often to help insurers review information more efficiently and apply decisions more consistently. Importantly, it is not a replacement for human expertise. In an area as personal and sensitive as health, the best outcomes are likely to come from getting the balance right.
Why AI is being used in underwriting
One of AI’s biggest strengths is speed. Medical underwriting can involve reviewing health disclosures, medical reports and previous information about similar conditions, which can sometimes take days or weeks. AI-driven systems can assess large volumes of information quickly, helping insurers reach decisions sooner and reducing some of the uncertainty that can come with waiting for an outcome.
It can also support greater consistency. While experienced underwriters bring valuable judgement, human decisions can naturally vary from case to case. AI applies set rules in a more uniform way, which can help reduce inconsistencies and manual error. With the right data and careful oversight, it may also support more accurate risk assessment and fairer decisions for applicants.
Another advantage is the ability to use data more intelligently. Information such as claims experience, treatment trends and wider medical outcomes can help insurers move beyond broad assumptions. In practice, this could mean some applicants receive more personalised decisions, standard terms where appropriate, or fewer blanket exclusions, helping the process feel more considered and proportionate.
Where human expertise still matters
That said, AI has its limits. It is strong at identifying patterns, but it cannot fully understand every medical nuance or personal circumstance. Underwriting decisions often depend on how a condition is managed, how symptoms present, treatment history, lifestyle factors and how one person’s situation differs from another’s. In more complex cases, a purely automated approach may be too cautious or miss important detail, which is why human judgement remains important.
The customer experience is also important. Protection decisions are closely linked to health, family security and financial resilience, so clear explanations matter. When an application results in a higher premium, an exclusion or a request for more information, people need to feel confident that the decision has been made fairly and that personal circumstances have been properly considered.
As AI takes on more routine cases, the role of the underwriter is likely to evolve rather than disappear. Human expertise may become even more valuable in complex or borderline cases, where judgement, context and empathy are critical to reaching a fair outcome.
The future is likely to be a blend of both
The future of medical underwriting is unlikely to be about choosing between AI and human expertise. More realistically, it will be about combining both in the right way. AI can support speed, efficiency and consistency in straightforward applications, while experienced underwriters provide oversight where health details or personal circumstances require closer review.
For customers, that balance will be key. Rather than removing the personal element, the aim should be to use technology to support better, more informed decisions.
