What Medicare edits apply to N29?
The Medicare Code Editor screens inpatient claims before they are grouped. These edits name N29 directly.
This code describes a manifestation of an underlying disease. The underlying condition must be sequenced before it, so it can never be the principal or first-listed diagnosis.
Which MS-DRGs does N29 group to?
N29 sits in MDC 11 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

How is N29 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to N29. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Nephrocalcinosis
- Calcification › kidney › tuberculous
- Degeneration, degenerative › kidney › amyloid
- Disorder › ureter › schistosomiasis (of)
- Disease, diseased › kidney › in › schistosomiasis
- Disease, diseased › ureter › in › schistosomiasis
- Disorder › kidney › in › schistosomiasis (of)
Excludes1 — never code together
The conditions below can never be reported together with N29 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Code first
The underlying condition below must be sequenced before N29. N29 describes a manifestation and cannot be the principal or first-listed diagnosis.
Excludes2 — not included here — inherited from Chapter 14
The conditions below are not part of N29, but a patient may have both at the same time. When documentation supports it, N29 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
The conditions below are not part of N29, but a patient may have both at the same time. When documentation supports it, N29 and the excluded code may both be reported.
- disorders of kidney and ureter with urolithiasis (N20-N23)
How long has N29 existed?
N29 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.
Which codes are confused with N29?
ICD-10-CM declares these codes mutually exclusive with N29 — exactly one of each pair can be correct for a given encounter.
