If a hospital says a nationally negotiated drug is out of stock or not stocked, have the doctor write the prescription and buy it at a designated pharmacy in the medical insurance “dual-channel” (双通道) system; it is still reimbursed under the rules

In plain words

If a hospital says a nationally negotiated drug (国家谈判药) is out of stock or not stocked, that does not mean the drug can't be reimbursed. If the drug is on your province's “dual-channel” (双通道) list, have the doctor write the prescription as usual and buy it at a designated “dual-channel” pharmacy; the reimbursement policy is the same as buying at the hospital. Under national documents, a hospital also may not use the total medical insurance budget or the share of spending on drugs as a reason to stall on supplying it.
