How is N02.B listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to N02.B. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Nephropathy › IgA

Excludes1 — never code together — inherited from N00-N08

The conditions below can never be reported together with N02.B on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • hypertensive chronic kidney disease (I12.-)

Excludes1 — never code together — inherited from N02

The conditions below can never be reported together with N02.B on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • acute cystitis with hematuria (N30.01)
  • hematuria NOS (R31.9)
  • hematuria not associated with specified morphologic lesions (R31.-)

Excludes2 — not included here — inherited from Chapter 14

The conditions below are not part of N02.B, but a patient may have both at the same time. When documentation supports it, N02.B and the excluded code may both be reported.

  • 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 — inherited from N00-N08

Two codes may be needed to describe the condition fully. Whether N02.B is sequenced first depends on the reason for the encounter.

  • any associated kidney failure (N17-N19).
