CMS has said that while ICD-10 expands the number of codes, a large portion of ICD-10 codes only differ in one parameter. For example, nearly 25% of ICD-10 codes are the same except for indicating the right side of the patient's body versus the left. Another 25% of the codes differ only in the way they distinguish among "initial encounter," versus "subsequent encounter," versus "sequelae."
Still, increased code detail contained in ICD-10 means that required clinical documentation by providers "will change substantially," according to CMS. ICD-10 includes a more robust definition of severity, comorbidities, complications, sequelae, manifestations, causes, and a variety of other important parameters that characterize the patient's condition, CMS said.
The move to ICD-10 doesn't impact just technology, but also an organization's business processes, people, and partners. The chart above (click here for a larger image), provided by IT services firm Cognizant Technology which performs ICD-10 remediation work, illustrates how the transition from ICD-9 to ICD-10 impacts payers and providers.
