  Health insurance plays a significant role in ensuring quality healthcare. In
response to the escalating costs of the medical industry, the demand for health
insurance is soaring. Additionally, those with health insurance are more likely
to receive preventative care than those without health insurance. However, from
granting health insurance to delivering services to insured individuals, the
health insurance industry faces numerous obstacles. Fraudulent actions, false
claims, a lack of transparency and data privacy, reliance on human effort and
dishonesty from consumers, healthcare professionals, or even the insurer party
itself, are the most common and important hurdles towards success. Given these
constraints, this chapter briefly covers the most immediate concerns in the
health insurance industry and provides insight into how blockchain technology
integration can contribute to resolving these issues. This chapter finishes by
highlighting existing limitations as well as potential future directions.
