After cancer surgery, many people look at policies they bought years ago and come across an unfamiliar item: a permanent-impairment (disability) benefit, known in Korean insurance as 후유장해. Unlike a lump-sum diagnosis benefit paid simply because cancer was diagnosed, this benefit rests on a different idea — what lasting loss of function or bodily impairment remains after treatment, expressed as a disability rating (a percentage).
Operations that remove part or all of an organ — such as the stomach, bowel, or liver — may qualify as an impairment depending on how much function is lost. However, how 'how much was removed' and 'how much function remains' are measured depends on the disability classification table attached to your specific policy. These tables changed over the years, and each insurer and product may word the criteria slightly differently, so it is hard to say in advance that a given operation automatically equals a fixed percentage.
A common snag is a difference in wording between documents. A surgeon may say verbally that 'two-thirds was removed,' while the medical certificate or operative record describes it differently, such as 'resection of roughly 50% or more of the lower portion.' Insurers assess claims based on what is written in the documents, not on spoken recollection, so the described extent and wording can be what decides the outcome. If the figures seem to differ from what actually happened, you can ask your medical team to confirm that the records accurately reflect the surgical findings.
Permanent-impairment claims are usually assessed after treatment has largely settled and the condition is stable, using an impairment diagnosis certificate. Such a certificate does not simply produce whatever result a patient asks for; the medical team documents the remaining functional status based on examinations and findings. Some ratings can also be re-evaluated later if the condition changes.
In short, when you have questions about an impairment benefit, it helps to: (1) first read your own policy terms and the disability classification table inside them; (2) check that the extent of surgery and any loss of function are accurately captured in the documents; and (3) when things are unclear, ask both your medical team and a qualified insurance or claims-assessment channel. Whether a claim is paid depends on the individual's condition and the policy wording, so it is best not to apply a stranger's online example directly to your own case.
