The first-level insured (former employee medical insurance) establishes individual accounts, which are divided into "basic account" and "public supplementary accounts". Among them, the "public supplementary account" refers to the supplementary personal account established by the insured who enjoys the subsidy for civil servants, that is, the "public supplementary account" shown on the settlement invoice or list. "basic account" refers to the part of the insured person's medical expenses that meet the requirements when seeking medical treatment and are paid by the overall fund according to the prescribed proportion.

Social medical insurance card, referred to as medical insurance card or medical insurance card, is a special card for personal account of medical insurance. With the personal identity card as the identification code, the detailed information such as personal identity card number, name, gender, account capital expenditure and consumption are stored and recorded. The medical insurance card is undertaken by the local designated agent bank, which is a multi-functional debit card of the bank. After the insured unit pays the fee, the local medical insurance department will entrust the bank to transfer the personal account payment to the personal medical insurance card of the insured employee at the end of the month.
