Wiki E11.21 vs E11.22

When I code any CKD N18.1 - N18.9 and DM is present E11.22 should be used and not E11.21, followed by the N code. E11.22 states within its code DM with CKD therefore it is a more accurate code than E11.21 which is just DM with Nephropathy (any kidney condition). I am not aware that E11.21 and E11.22 have an excludes 1 notes therefore they can be coded together as long as a separate renal manifestation is present, I would just be careful when coding the actual renal condition as there are some renal codes that are excluded when using CKD codes.
