Recurrent and persistent hematuria (N02)
ICD-10 code N02 covers recurrent and persistent hematuria, which means ongoing or repeated presence of blood in the urine. This group of codes is specifically used to classify hematuria linked to various underlying kidney abnormalities and glomerular diseases.
The ICD-10 code for recurrent and persistent hematuria includes subcategories that describe different kidney pathologies causing this condition. Codes like N02.0 and N02.1 identify hematuria due to minor glomerular abnormalities or focal and segmental lesions, respectively. Other subcodes, such as N02.2 through N02.7, cover specific types of glomerulonephritis, like diffuse membranous, mesangial proliferative, endocapillary proliferative, mesangiocapillary, dense deposit disease, and crescentic glomerulonephritis. For example, if a patient has persistent hematuria caused by diffuse endocapillary proliferative glomerulonephritis, the appropriate code would be N02.4. Additionally, the section includes codes for immunoglobulin A (IgA) nephropathy-related hematuria (N02.B series) and unspecified morphologic changes (N02.9). Using these codes helps healthcare professionals accurately document hematuria connected to specific kidney conditions, aiding in diagnosis and treatment planning.

Instructional Notations
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.
