N00.B — Acute nephritic syndrome with immune complex membranoproliferative glomerulonephritis

Not billable

Is N00.B billable?

No — N00.B is a non-billable header code. N00.B groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 2 billable codes beneath N00.B.

Excludes1 — never code together — inherited from N00-N08

The conditions below can never be reported together with N00.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 N00

The conditions below can never be reported together with N00.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 tubulo-interstitial nephritis (N10)
  • nephritic syndrome NOS (N05.-)

Excludes2 — not included here — inherited from Chapter 14

The conditions below are not part of N00.B, but a patient may have both at the same time. When documentation supports it, N00.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 N00.B is sequenced first depends on the reason for the encounter.

  • any associated kidney failure (N17-N19).
