Proteinuria (R80) ICD-10-CM
The R80 code range covers proteinuria with 7 ICD-10-CM diagnosis codes. 6 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the R80 range.
Albuminuria
The presence of albumin in the urine, an indicator of KIDNEY DISEASES.
Kidney Diseases
Pathological processes of the KIDNEY or its component tissues.
Pre-Eclampsia
A complication of PREGNANCY, characterized by a complex of symptoms including maternal HYPERTENSION and PROTEINURIA with or without pathological EDEMA. Symptoms may range between mild and severe. Pre-eclampsia usually occurs after the 20th week of gestation, but may develop before this time in the presence of trophoblastic disease.
Proteinuria
The presence of proteins in the urine, an indicator of KIDNEY DISEASES.
Pyuria
The presence of white blood cells (LEUKOCYTES) in the urine. It is often associated with bacterial infections of the urinary tract. Pyuria without BACTERIURIA can be caused by TUBERCULOSIS, stones, or cancer.
About the R80 Code Range
Proteinuria is coded under ICD-10 code R80 and its subcategories, which classify the presence of abnormal protein levels in the urine. These codes are essential for identifying various forms of proteinuria that indicate kidney function issues or other medical conditions.
The main code, R80, broadly covers proteinuria. More specific codes help detail the condition: R80.0 is for isolated proteinuria without other symptoms. R80.1 captures persistent proteinuria seen in conditions like type 1 and type 2 diabetes, often referred to as microalbuminuria or diabetic nephropathy. R80.2 describes orthostatic proteinuria, which occurs when protein appears in urine during upright posture but not lying down. R80.3 identifies Bence Jones proteinuria, related to light-chain proteins often found in multiple myeloma. R80.8 includes other less common types such as nephrogenous or febrile proteinuria. Finally, R80.9 is used when the proteinuria type is unspecified or when proteinuria is documented without additional detail. Using these specific codes helps medical professionals accurately record and manage different causes and presentations of proteinuria in clinical practice.
