Chronic kidney disease, unspecified
ICD-10 N18.9 is a billable code used to indicate a diagnosis of chronic kidney disease, unspecified.
Chronic kidney disease (CKD) is a progressive condition characterized by a gradual loss of kidney function over time. It is classified into five stages based on the glomerular filtration rate (GFR), with stage 1 indicating mild damage and stage 5 representing kidney failure requiring dialysis or transplantation. The unspecified designation (N18.9) is used when the specific stage of CKD is not documented or when the patient has not undergone sufficient testing to determine the stage. CKD can result from various underlying conditions, including diabetes, hypertension, and glomerulonephritis. Patients may experience symptoms such as fatigue, swelling, and changes in urination. Management of CKD focuses on slowing progression through lifestyle modifications, controlling blood pressure and blood sugar levels, and monitoring kidney function. In advanced stages, renal replacement therapy, including dialysis or kidney transplantation, may be necessary. Accurate coding is essential for appropriate treatment planning and reimbursement.
Detailed documentation of kidney function tests, patient history, and treatment plans.
Patients with diabetes or hypertension presenting with CKD symptoms.
Ensure clear documentation of CKD stage and any renal replacement therapy.
Regular monitoring of kidney function and management of comorbid conditions.
Routine screening of at-risk populations for CKD.
Document any referrals to nephrology for further evaluation.
Used for patients with CKD stage 5 requiring dialysis.
Document the need for dialysis and patient consent.
Nephrology must ensure proper documentation of dialysis sessions.
Use N18.9 when the patient has chronic kidney disease but the specific stage is not documented or cannot be determined based on available information.
