2025 ICD-10-CM code E11.22
(Active) Effective Date: N/A Diabetes mellitus - Diabetes mellitus with kidney complications 4 Endocrine, nutritional and metabolic diseases Feed
Type 2 diabetes mellitus with diabetic chronic kidney disease.
Medical necessity for services related to diabetic chronic kidney disease is established by the documented presence of the condition and its severity. Further testing and treatment are justified based on the stage of CKD and associated complications.
Clinicians should document the stage of chronic kidney disease using codes N18.1-N18.6 in addition to E11.22. It is important to distinguish diabetic chronic kidney disease from diabetic nephropathy (E11.21), as diabetic nephropathy is a more specific diagnosis characterized by advanced renal disease due to microvascular damage and proteinuria.
In simple words: This means the person has type 2 diabetes, and it has caused long-term kidney problems. It's important to also note how severe the kidney problems are with a separate code.
Type 2 diabetes mellitus with diabetic chronic kidney disease. This code indicates that the patient has type 2 diabetes which has caused chronic kidney disease. Use additional code to identify the stage of chronic kidney disease (N18.1-N18.6).
Example 1: A patient with type 2 diabetes presents with elevated creatinine and reduced glomerular filtration rate (GFR), indicating stage 3 chronic kidney disease. Both E11.22 and N18.3 would be coded., A patient with type 2 diabetes is on dialysis due to end-stage renal disease (ESRD) secondary to diabetes. The codes E11.22 and N18.6 would be used., A patient with a long history of type 2 diabetes is diagnosed with mild chronic kidney disease (stage 2) based on lab results. Both E11.22 and N18.2 are reported.
Documentation should clearly link the CKD to the type 2 diabetes. Lab results such as creatinine, BUN, GFR, and urine albumin are essential. The stage of CKD should be explicitly stated.
