N02 is a non-billable ICD-10-CM category code for recurrent and persistent hematuria, so it cannot be submitted on claims. Use a more specific code from this category instead, such as N02.0, N02.1, N02.2, and N02.3.

Specific Coding for Recurrent and persistent hematuriaOverview

Non-specific codes like N02 require more characters. Use one of these billable codes instead:

  • Use N02.0 for Recurrent and persistent hematuria with minor glomerular abnormality

  • Use N02.1 for Recurrent and persistent hematuria with focal and segmental glomerular lesions

  • Use N02.2 for Recurrent and persistent hematuria with diffuse membranous glomerulonephritis

  • Use N02.3 for Recurrent and persistent hematuria with diffuse mesangial proliferative glomerulonephritis

  • Use N02.4 for Recurrent and persistent hematuria with diffuse endocapillary proliferative glomerulonephritis

  • Use N02.5 for Recurrent and persistent hematuria with diffuse mesangiocapillary glomerulonephritis

  • Use N02.6 for Recurrent and persistent hematuria with dense deposit disease

  • Use N02.7 for Recurrent and persistent hematuria with diffuse crescentic glomerulonephritis

  • Use N02.8 for Recurrent and persistent hematuria with other morphologic changes

  • Use N02.9 for Recurrent and persistent hematuria with unspecified morphologic changes

  • Use N02.A for Recurrent and persistent hematuria with C3 glomerulonephritis

  • N02.B for Recurrent and persistent immunoglobulin A nephropathy

  • Use N02.B1 for Recurrent and persistent immunoglobulin A nephropathy with glomerular lesion

  • Use N02.B2 for Recurrent and persistent immunoglobulin A nephropathy with focal and segmental glomerular lesion

  • Use N02.B3 for Recurrent and persistent immunoglobulin A nephropathy with diffuse membranoproliferative glomerulonephritis

  • Use N02.B4 for Recurrent and persistent immunoglobulin A nephropathy with diffuse membranous glomerulonephritis

  • Use N02.B5 for Recurrent and persistent immunoglobulin A nephropathy with diffuse mesangial proliferative glomerulonephritis

  • Use N02.B6 for Recurrent and persistent immunoglobulin A nephropathy with diffuse mesangiocapillary glomerulonephritis

  • Use N02.B9 for Other recurrent and persistent immunoglobulin A nephropathy

Patient EducationClinical

Urine and Urination

Your kidneys make urine by filtering wastes and extra water from your blood. The waste is called urea. Your blood carries it to the kidneys. From the kidneys, urine travels down two thin tubes called ureters to the bladder. The bladder stores urine until you are ready to urinate.

Questions About N02Overview

Is N02 (Recurrent and persistent hematuria) a billable code?

No. This is a category header that groups the codes for recurrent and persistent hematuria, and headers cannot be submitted on claims. Claims for recurrent and persistent hematuria need a more specific code from this category, such as N02.0, N02.1, and N02.2.
