Summary of ICD-10

ICD-10 is coming to US healthcare in 2013. CMS has created a nice summary of the motivation for shifting to ICD-10 and some examples of the changes.

There are pros and cons on many fronts around shifting to ICD-10. From an integration standpoint, most codes are carried in HL7 as a CE data type. This means that HL7 is by-and-large “already prepared” for ICD-10.

The real work will be in end user applications and, IMO, in the user experience of selecting much more specific codes. In short, ICD-10 provides pre-coordinated codes and ultimately suffers from inconsistency in code construction — this will make the GUI design and selection process very ugly indeed.For example, Pressure ulcer codes go from a choice of 9 to a choice of 125.

Rich Elmore discusses the “large code set problem” in a 2008 blog posting where he uses the example of a simple code (“insect bite”) and compares ICD-9 and ICD-10. Coding this simple example is much harder in ICD-10.
