ICD-10 Code: E11.22
Type 2 Diabetes Mellitus with Diabetic Chronic Kidney Disease
Type 2 diabetes mellitus with chronic kidney disease (CKD) represents progressive kidney damage caused by longstanding diabetes, characterized by persistent albuminuria and/or declining glomerular filtration rate (GFR) attributable to diabetic nephropathy.
Clinical Information
Coding Guidelines
- 1Use additional code to identify stage of chronic kidney disease (N18.1-N18.6) - this is REQUIRED per ICD-10-CM guidelines
- 2Code E11.22 is used when diabetic nephropathy or CKD is documented as being caused by diabetes
- 3If patient has both diabetes and CKD but causality is not established, code separately (E11.9 and N18.x)
- 4Do not assume causality; provider must link the CKD to diabetes in documentation
- 5For patients on dialysis, use additional code Z99.2 (dependence on renal dialysis)
- 6For kidney transplant status, add Z94.0
Common Uses
- Annual diabetic screening reveals new-onset microalbuminuria with GFR 55 mL/min
- Follow-up for established diabetic CKD with monitoring of kidney function
- Nephrologist visit for progressive diabetic nephropathy requiring treatment adjustment
- Hospitalization for acute on chronic kidney injury in diabetic patient
- Initiation of dialysis in patient with diabetes-induced ESRD
- Pre-operative clearance documenting diabetic CKD as comorbidity
Related ICD-10 Codes
Documentation Requirements
- Provider must explicitly document causal relationship: 'diabetic kidney disease,' 'diabetic nephropathy,' or 'CKD due to diabetes'
- Document specific CKD stage based on GFR (Stage 1: ≥90, Stage 2: 60-89, Stage 3: 30-59, Stage 4: 15-29, Stage 5: <15 mL/min/1.73m²)
- Include albuminuria status if available (urine albumin-to-creatinine ratio or 24-hour protein)
- Most recent serum creatinine and calculated GFR/eGFR
- Document dialysis dependence if applicable
- Current treatment regimen (ACE inhibitor, ARB, dietary restrictions, etc.)
Real-World Coding Examples
Patient with 15-year history of type 2 diabetes presents for follow-up. Labs show serum creatinine 2.1 mg/dL, eGFR 32 mL/min/1.73m², urine albumin-to-creatinine ratio 450 mg/g. Diagnosis: Type 2 diabetes with diabetic chronic kidney disease, stage 3b (E11.22, N18.3).
Nephrologist visit for diabetic patient. Documentation states 'diabetic nephropathy with declining renal function.' eGFR 22 mL/min. Diagnosis: Type 2 diabetes mellitus with diabetic CKD, stage 4 (E11.22, N18.4). Plan: Pre-dialysis education.
68-year-old with diabetes presents to ED with uremia symptoms. Creatinine 8.5 mg/dL, eGFR 8 mL/min. Admitted for dialysis catheter placement. Diagnosis: Type 2 diabetes with diabetic ESKD (E11.22, N18.6). Dialysis initiated.
