NWCA Medical Billing And Coding Practice Exam

Upcoding and downcoding are forms of misrepresenting the level of service through coding. Upcoding means using a code that reflects a more severe diagnosis or higher complexity of services than what was actually performed and documented, with the aim of getting higher payment. Downcoding means assigning a lower-severity code than the documentation supports, which still misrepresents the true level of service. Both practices violate coding guidelines because the code should accurately reflect what was done and documented in the medical record. When the documentation supports a higher level of care, that higher code should be used; when it supports a lower level, the lower code is appropriate. Deliberate misrepresentation to influence payment undermines payer trust, can lead to audits, recoupment of funds, civil penalties, and even criminal action under fraud and abuse laws. The proper approach is to code exactly what is documented and medically necessary, and to clarify with the clinician if the chart is unclear.
