A type of insurance called medical insurance covers all or a portion of the risk associated with a person needing medical care. An insurer can create a regular financial structure, such as a monthly premium or payroll tax, to provide the funds to pay for the medical benefits provided in the insurance agreement by assessing the overall risk of health risk and health system expenses over the risk pool. Blockchain, which is most commonly described as a shared, immutable ledger, has the potential to reinvent these procedures as well as many others. Blockchain technology has applications well beyond bitcoin. Medical insurance claims or medi- claims must be made in urgent or catastrophic instances where medical crises occur.It can be inconvenient during such emergency situations and takes a lot of time to get the insurance claimed. In order for the medi- claim to be approved, patient's family members must chase after banks and insurance providers. The suggested system functions like a blessing in these circumstances. The proposed system ensures that the likelihood of fraud is extremely low while simultaneously speeding up the insurance claim procedure. Blockchain technology offers operational, regulatory, increased visibility, and traceability verification efficiencies. This technology also functions as a strong database that may be coupled with big data with ease. Blockchain technology can reduce costs and boost the competitiveness of numerous services.
