Fraudulent Medical Bills Alert! Are your medical bills "upcoded"? RAND says there is a strong possibility

[ck4829]

What is upcoding? “Upcoding” occurs when a healthcare provider submits codes to Medicare, Medicaid, or private insurers for more serious (and more expensive) diagnoses or procedures than the provider actually diagnosed or performed.

Upcoding is one of the biggest bones of contention between U.S. payers and providers, which in this context are mainly hospitals. Payers say providers upcode to higher severity levels with little, if any, medical justification as a way to increase payment levels. Providers counter that the patients that they are taking care of are sicker and that coding at a higher severity is warranted.

In this back-and-forth, the results from a RAND study published in Health Affairs put some persuasive evidence behind the argument that payers have been making.

Daniel Crespin, Ph.D., M.S.P.H., a policy researcher at RAND and lead author of the study, and his colleagues had access to hospital inpatient databases prepared by the Healthcare Cost and Utilization Project for Florida, Kentucky, New York, Washington state, and Wisconsin.

They found that the discharges with the highest severity level increased from 17.2 per 1,000 population in 2011 to 24.2 per 1,000 population in 2019, a 41% increase. When they factored in patient characteristics, length of stay and hospital characteristics, they estimated that the increase would have been just 13%. Put another way, Crespin and his colleagues found that only one-third of the increase in severity could be explained by “observable” discharge and patient and hospital characteristics, and that the remaining two-thirds could be chalked up to upcoding.
