What ICD-10 Codes are Used for Proteinuria

Proteinuria is a medical condition characterized by excess protein in the urine. In the ICD-10 coding system, several codes are used to classify and document cases of proteinuria.

Here are the commonly used Proteinuria ICD-10 codes, along with their clinical descriptions:

  • Nephrotic syndrome (N04.9): Nephrotic syndrome is a kidney disorder that often results in severe proteinuria, typically with an albumin-to-creatinine ratio greater than 3.5. It can lead to edema, hypoalbuminemia, and hyperlipidemia.
  • Chronic kidney disease, stage 1 (N18.1): In this early stage of chronic kidney disease (CKD), proteinuria is one of the markers of kidney damage. The glomerular filtration rate (GFR) remains normal or only slightly reduced.
  • Chronic kidney disease, stage 2 (N18.2): CKD stage 2 indicates a mild reduction in kidney function with persistent proteinuria. The GFR is moderately reduced.
  • Chronic kidney disease, stage 3 (N18.3): This stage signifies moderate CKD, where proteinuria often coexists with declining kidney function (GFR). It may require more intensive monitoring and management.
  • Diabetic nephropathy (E11.21): Diabetic nephropathy is a common complication of diabetes, characterized by proteinuria and kidney damage. Proper management is crucial to slow its progression.
  • Hypertensive nephropathy (I12.9): Hypertensive nephropathy occurs when chronic high blood pressure leads to kidney damage, often presenting with proteinuria. Control of blood pressure is essential to manage this condition.
  • IgA nephropathy (N01.9): IgA nephropathy, also known as Berger’s disease, is an immune system disorder leading to the deposition of IgA antibodies in the kidneys. Proteinuria is a common feature of this condition.
  • Alport syndrome (Q87.8): Alport syndrome is a genetic disorder affecting the kidneys and often resulting in proteinuria, hematuria, and hearing loss. Early diagnosis and management are crucial.
  • Nephritic syndrome, not otherwise specified (N05.9): Nephritic syndrome is characterized by hematuria, proteinuria, and hypertension. This code is used when a specific cause is not identified.
  • Proteinuria, unspecified (R80.9): When the underlying cause of proteinuria is not clear, or the condition is not otherwise specified, this code is used to document the presence of proteinuria in the patient.

These ICD-10 codes and clinical descriptions help healthcare professionals accurately document and track cases of proteinuria, allowing for appropriate diagnosis and treatment of the underlying conditions. Proper coding is essential for effective patient care and medical research.
