N26Unspecified contracted kidney

Not billable

Is N26 billable?

No — N26 is a non-billable header code. N26 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 3 billable codes beneath N26.

Excludes1 — never code together

The conditions below can never be reported together with N26 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • contracted kidney due to hypertension (I12.-)
  • diffuse sclerosing glomerulonephritis (N05.8.-)
  • hypertensive nephrosclerosis (arteriolar) (arteriosclerotic) (I12.-)
  • small kidney of unknown cause (N27.-)

Excludes2 — not included here — inherited from Chapter 14

The conditions below are not part of N26, but a patient may have both at the same time. When documentation supports it, N26 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)

Excludes2 — not included here — inherited from N25-N29

What codes fall under N26? (3)

How long has N26 existed?

N26 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
