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

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to N02: its own notes plus those printed at block N00-N08 and Chapter 14. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

On N02 itself
  • acute cystitis with hematuria (N30.01)
  • hematuria NOS (R31.9)
  • hematuria not associated with specified morphologic lesions (R31.-)
From Block N00-N08 Glomerular diseases applies to 107 codes
  • hypertensive chronic kidney disease (I12.-)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 14 (N00-N99) Diseases of the genitourinary system applies to 838 codes
  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

Code Also

A second code may be needed to fully describe the condition; the note gives no sequencing direction.

From Block N00-N08 Glomerular diseases applies to 107 codes
  • any associated kidney failure (N17-N19).

Referenced in Other NotesGuidance

Instructional notes printed at other codes that name N02, its category, or a range that includes it.

Excludes1 1

These codes carry an Excludes1 note naming N02: they are not reported together with it, unless the two conditions are unrelated.

  • R31 Hematuria
    recurrent and persistent hematuria in glomerular diseases (N02.-)

Excludes2 2

These codes carry an Excludes2 note naming N02: its condition is not part of those codes, and both may be reported when the patient has both.

  • N39 Other disorders of urinary system
    recurrent or persistent hematuria (N02.-)
  • N39 Other disorders of urinary system
    recurrent or persistent hematuria with specified morphological lesion (N02.-)

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

What is the ICD-10 code for recurrent and persistent hematuria?

N02 is the ICD-10-CM category for recurrent and persistent hematuria, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

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.

Can N02 be reported with N30.01?

Not as a rule. The Excludes1 note on N02 lists "acute cystitis with hematuria (N30.01)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
