Official Coding Guidelines
CKD staging and code assignment (N18.-)The ICD-10-CM classifies CKD based on severity. The severity of CKD is designated by stages 1-5. Stage 2, code N18.2, equates to mild CKD; stage 3, codes N18.30-N18.32, equate to moderate CKD; and stage 4, code N18.4, equates to severe CKD. Code N18.6, End stage renal disease (ESRD), is assigned when the provider has documented end- stage renal disease (ESRD).
CKD stage plus ESRD: assign N18.6 onlyIf both a stage of CKD and ESRD are documented, assign code N18.6 only.
