Step 3 Problem of not understanding item meanings on hospital receipts and being unable to judge over-treatment

Problem

A worker in their 50s manages the hospital receipts of their 75-year-old parents monthly. Terms like 'selective benefits,' 'non-covered procedure fees,' and 'differential drug copayment rates' are complex, making it impossible to determine how much of the total 200,000 KRW is eligible for National Health Insurance reimbursement or whether non-covered items are appropriate. Despite spending 3-5 million KRW annually on hospital bills, they fail to apply for the out-of-pocket maximum reimbursement (800,000-1.2 million KRW per year), missing out on hundreds of thousands of won each year, and often omit claims for supplementary private insurance.

Solution

When a hospital receipt is photographed, OCR automatically recognizes items and explains each in plain language. It tracks cumulative annual out-of-pocket expenses and sends alerts when the user becomes eligible for out-of-pocket maximum reimbursement. Non-covered items are compared with average prices at other hospitals for the same procedure to indicate reasonableness. It also provides a document checklist for supplementary private insurance claims.

Target: Working adults aged 48-58 who support parents aged 70+ and manage their hospital expenses, accompanying parents to hospital at least once a month.

Revenue Model: Free for 3 receipt decodes per month. Unlimited decoding + annual cumulative tracking + reimbursement alerts + insurance claim guide: 3,900 KRW/month (approx. $2.93). B2B patient family service for long-term care hospitals and senior living communities: 100,000 KRW/month (approx. $75).
