In recent years, with the continuous improvement of medical insurance reimbursement levels, the scope of drugs in the medical insurance catalog has gradually expanded, making it more convenient for insured individuals to purchase medication. Hospitals, pharmacies, clinics, and even online can purchase medication and enjoy medical insurance reimbursement. However, these policies have also caused some unscrupulous individuals to have ulterior motives, and many drug traffickers have induced insured individuals to participate in drug sales through "high price recycling". This kind of disguised recovery of drugs purchased by insured individuals after enjoying medical insurance reimbursement and reselling them is called medical insurance "return drugs". The National Medical Insurance Administration recently reminded that one should not become an accomplice to drug traffickers for the sake of small profits, causing irreparable losses to oneself and others. To put it another way, the so-called "return medicine" refers to the act of using someone else's medical insurance certificate, or the insured person using medical insurance reimbursement to purchase drugs from designated medical institutions, and selling them to drug recyclers at an additional price on the basis of personal actual payment of drug purchase fees. Drug recyclers sell drugs to medical institutions, clinics, etc., and medical institutions and clinics resell them to patients. For example, if a medical insurance insured person pays 10 yuan at their own expense and prescribes a medicine with a total price of over 100 yuan, with the help of a drug dealer, even if it is only sold for 50 yuan, both can earn 40 yuan from it. From this, it can be seen that the participation of medical insurance participants in reselling "return drugs" is a fraudulent behavior, resulting in the medical security fund that should have been used to save lives being encroached upon by criminals. The medical insurance fund is the "life-saving money" of the people. Maintaining the safety of the medical insurance fund is related to the vital interests of the people and the fairness and sustainability of the medical security system. If some insured individuals excessively or falsely prescribe drugs for a long time, it will not only cause a significant increase in the funding gap of the medical insurance fund without reason, but also result in serious waste of medical resources. In addition to eroding the medical insurance fund, reselling "returning drugs" also endangers medication safety. Not to mention that "reflux drugs" are not separated from the necessary temperature and humidity conditions for drug storage, making it difficult to guarantee the quality of drugs. Recently, the National Medical Insurance Administration revealed that some drug dealers have filled fake drugs into drug boxes and sold them to pharmacies, using fake drugs as fake ones; Due to the fact that the expiration date of drugs is not directly printed on the tablets, some drug dealers remove expired or expired drugs from their original packaging and put them into new drug boxes, wearing them with great care; Drug traffickers often confuse dosage specifications and drug types during the process of dismantling and restructuring "reflux drugs"... Based on this, relevant departments have been committed to cracking down on the practice of reselling "reflux drugs". In February of this year, the Supreme People's Court, the Supreme People's Procuratorate, and the Ministry of Public Security jointly issued the "Guiding Opinions on Several Issues Concerning Handling Criminal Cases of Medical Insurance Fraud", which clearly stated that those who knowingly purchase or sell drugs purchased through medical insurance fraud shall be convicted and punished for covering up or concealing the crimes committed; Those who instigate, instigate, or instruct others to use medical insurance to fraudulently purchase drugs, and then illegally purchase or sell them, shall be convicted and punished for the crime of fraud. One of the most crucial priorities in cracking down on the resale of "returning drugs" is to strengthen the defense line of insured individuals. On the one hand, it is necessary to strengthen the publicity and education of relevant laws and regulations for the vast number of insured persons. For example, according to the Regulations on the Supervision and Administration of the Use of Medical Insurance Funds, individuals who use the opportunity to enjoy medical insurance benefits to resell drugs, accept cash or physical returns, or obtain other illegal benefits for the purpose of fraudulently obtaining medical insurance funds, resulting in losses to the medical insurance funds, shall suspend their medical expense networking
