Clinical documentation improvement, also known as "clinical documentation integrity", is the best practices, processes, technology, people, and joint effort between providers and billers that advocates the completeness, precision, and validity of provider documentation inherent to transaction code sets sanctioned by the Health Insurance Portability and Accountability Act in the United States. The profession was developed in response to the Centers for Medicare and Medicaid Services Diagnostic-Related Group system in 1983 and gained greater notice around 2007 with CMS's transition to Medicare-Severity Diagnosis-Related Groups. With the expansion of risk-adjusted value-based payment and quality measures and increasing accountability by regulatory agencies, CDI now impacts at least 20 different models affecting payers, facilities, and providers. CDI professionals act as intermediaries between Inpatient coders who translate diagnoses into data and healthcare providers and nurses. As many clinical coders don't have patient care backgrounds, and healthcare providers might not realize the importance of accurate documentation, the CDI professional serves to make the connection between these two groups. CDI professionals should be familiar with Medicare Severity DRGs ICD-9 to ICD-10 coding.
