If my parents are added in health insurance, is there any copay for parents in case of hospitalisation? Or 100% hospital bill is covered.

Co pay is 7.5% to 12.5%. If treatment done in a network hospital without intimation then additional 10% will be deducted in case of reimbursement. Provided it is not an emergency hospitalisation like heart attack, accident etc

co pay between 7.5% to 12.5% based on BAND

Different plans different copay but yes copay is there for everyone
