There is almost no difference between ICD-9 and ICD-10 when it comes to coding chronic kidney disease. More dead wood was cleaned out of ICD-9 and a bit more useful detail added in ICD-10.
On the other hand, there are roughly half again as many anemia codes in ICD-10 as in ICD-9. Most of these are a straightforward expansion of detail, and if you provide documentation for the available detail in the codes, there is nothing tricky about using them. Most of these new detailed codes are for the rarer anemias. The most common anemias can be documented and coded just as they are now in ICD-9. And of course, the expanded classifications always contain an unspecified code for times when the detail is unavailable, and not worth your patient’s healthcare dollars to get.
Chronic Kidney Disease
The ICD-9 CKD codes have been themselves updated in recent years to imitate CKD as classified in ICD-10, so they pretty much match. Here are the bread and butter CKD codes in ICD-10.
