Denied a claim? Inside claim investigations, the legal meaning of 'accident', and how to protect yourself

People buy insurance for peace of mind. Yet when serious illness strikes and a claim is filed, many discover that the review process is exacting and slow. What exactly does an insurer investigate once a claim lands on its desk? And why can a self-paid medicine your doctor says will work still be refused?

This episode of Sick Needs Money welcomes Hung Ying-hsi, a veteran claims investigator who has seen countless disputes and now works as a licensed insurance loss adjuster. He walks listeners through how claim investigations really work, and the legitimate channels open to policyholders defending their rights.

1. What insurers are actually investigating

Hung explains that insurers investigate in two distinct phases:

• Pre-underwriting checks: assessing the applicant's build, medical history and lifestyle (smoking, drinking, betel nut), and even whether the named beneficiary is lawful and plausible, in order to price the risk.
• Post-event claims investigation: once a claim is filed, investigators visit the scene, the police station or the hospital to pull medical records and confirm the cause fits the policy wording.

Whether a case is investigated individually usually turns on the size of the claim, unusual background details (an oddly designated beneficiary, for example) and the cause of the event.

Insurers also run big-data 'red flag' systems. When a particular type of claim spikes abnormally over a short period, the system raises an alert and a thematic investigation begins, to screen out potential moral hazard.

2. Why accident cover stalls: clinical medicine vs. the legal test

Accident cover is where disputes concentrate. Many policyholders assume that anything sudden and severe counts as an accident, but under case law and insurance law an accident must satisfy three elements at once: external, sudden, and not caused by disease.

Take a rider found collapsed beside a scooter and later diagnosed with a brain bleed. The review has to establish causation:

• Caused by external impact: a subdural haematoma from the collision falls within accident cover.
• Caused by spontaneous disease: if the rider has hypertension, hyperglycaemia and hyperlipidaemia and fell because of a spontaneous stroke while riding, the root cause is disease and accident cover does not pay.

Even where the physician's certificate describes the injuries, insurers will ask for imaging (X-ray, CT, MRI) to read the injury pattern and decide on objective scientific evidence.

3. Denied? Loss adjusters and prior authorisation

When a dispute turns on medical necessity or whether a therapy fits the indication, the advice is: first understand calmly what medical evidence the insurer still needs, then read the policy closely, consult a professional agent, or seek the neutral opinion of a licensed loss adjuster.

Loss adjusters are often confused with claim touts, but the two are nothing alike:

• Licensed loss adjuster (a regulated profession): a state-examined insurance auxiliary supervised by the competent authority, who investigates, assesses and calculates on objective scientific evidence and issues a balanced report for both sides.
• Claim touts: no formal legal standing, working for a cut or unreasonable fees, often claiming inside connections or filing through irregular means — and exposing the client to criminal investigation when a case turns contentious.

Hung also points to prior authorisation, common in the United States, which lets a patient confirm coverage with the insurer before starting an expensive self-paid therapy. Taiwan mostly runs on pay-first-claim-later, which is precisely why arguments over indications erupt after the fact. Introducing prior authorisation would remove much of that friction.

4. Health literacy makes a smarter insurance consumer

As self-paid precision medicine advances, the costs involved are beyond what an ordinary household absorbs easily. Rather than fighting a long claims battle after the event, build health literacy and a clear view of your own cover in advance.

Review the policies you already hold, and when a medical decision arrives, talk it through early with your physician and a professional broker, weighing how the cost will be met. That is what buys composure when illness actually arrives.
