The complexity of and quantity of funds involved in Medicare reimbursements have led to a significant increase in the number of Medicare fraud. A particular kind of Medicare fraud, upcoding, has contributed to excessive and avoidable health care spending. Upcoding has been an illegal tactic that some providers have used to increase their Medicare reimbursement for specific medical conditions. This is accomplished by coding a provided service as a more expensive service than what was performed. With the proliferation of upcoding, there has been an unprecedented $12.5 billion in fraudulent Medicare charges. While solving the problem of upcoding will not eliminate the multiple contributing factors to this enormous healthcare expenditure, it would be a start.
