2025 ICD-10-CM code E10.22
(Active) Effective Date: N/A Endocrine, Nutritional and Metabolic Diseases - Diabetes mellitus 4 Feed
Type 1 diabetes mellitus with diabetic chronic kidney disease.
Medical necessity for the management of diabetic chronic kidney disease is established by the presence of type 1 diabetes and documented evidence of chronic kidney disease as a direct consequence of the diabetes. The stage of CKD helps to determine the appropriate level of care and interventions required.
Providers diagnose the condition based on history, physical examination, and signs and symptoms. Diagnostic tests include glucose tolerance tests, kidney function tests, GFR measurement, plasma glucose levels, HbA1c levels, CBC, urine for glucose, albumin, and ketones, and anti-insulin antibodies. Imaging studies include renal ultrasound. Renal biopsy may also be indicated.
In simple words: This code indicates that a person has type 1 diabetes, which is an autoimmune disease where the body's immune system attacks the cells in the pancreas that make insulin. As a result, the body can't produce enough insulin to regulate blood sugar levels. This code also signifies that the individual has chronic kidney disease caused by their diabetes.Chronic kidney disease means the kidneys are damaged and not working as well as they should.
Type 1 diabetes mellitus with diabetic chronic kidney disease. Use additional code to identify stage of chronic kidney disease (N18.1-N18.6).
Example 1: A patient with type 1 diabetes for 15 years presents with fatigue, swelling in the legs, and reduced urine output.Blood tests reveal elevated creatinine and decreased GFR, and urinalysis shows proteinuria.The provider diagnoses diabetic chronic kidney disease. Code E10.22 is used, along with a code specifying the stage of CKD (e.g., N18.3 for stage 3 CKD)., A young patient with type 1 diabetes is brought to the ER with severe abdominal pain, nausea, and vomiting. Blood tests reveal high blood glucose and ketones in the urine. After stabilization, further testing shows reduced kidney function. The provider documents both diabetic ketoacidosis and chronic kidney disease. E10.22 and a code for ketoacidosis (E10.10 or E10.11, depending on coma presence) are used, with an additional code for the CKD stage., A patient with long-standing type 1 diabetes and established chronic kidney disease undergoes regular dialysis. The patient is admitted to the hospital for treatment of a foot infection.E10.22, a code for the appropriate stage of CKD (likely N18.5 or N18.6 for end-stage renal disease), and Z99.2 (dependence on renal dialysis) are reported, along with a code for the foot infection.
Documentation should include evidence of type 1 diabetes, chronic kidney disease attributed to diabetes, and the stage of the chronic kidney disease. Supporting documentation could include laboratory results (e.g., elevated creatinine, decreased GFR, proteinuria), imaging studies (e.g., renal ultrasound), and clinical findings.
