N03.0 — Chronic nephritic syndrome with minor glomerular abnormality
Is N03.0 billable?
Yes — N03.0 is billable for FY2027. N03.0 is a valid, billable ICD-10-CM code at the highest level of specificity in its branch. N03.0 may be submitted for encounters from October 1, 2026 through September 30, 2027.

Which MS-DRGs does N03.0 group to?
N03.0 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.
- 698Other Kidney and Urinary Tract Diagnoses with MCCmedical
- 699Other Kidney and Urinary Tract Diagnoses with CCmedical
- 700Other Kidney and Urinary Tract Diagnoses without CC/MCCmedical
As a secondary diagnosis, N03.0 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
How is N03.0 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to N03.0. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Nephritis, nephritic › chronic › with › minor glomerular abnormality (albuminuric) (azotemic) (congenital) (disseminated) (epithelial) (familial) (focal) (granulomatous) (hemorrhagic) (infantile) (nonsuppurative, excretory) (uremic)
Inclusion terms
Alternative wording in documentation that is classified to N03.0.
- Chronic nephritic syndrome with minimal change lesion
Excludes1 — never code together — inherited from N00-N08
The conditions below can never be reported together with N03.0 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 N03
The conditions below can never be reported together with N03.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from Chapter 14
The conditions below are not part of N03.0, but a patient may have both at the same time. When documentation supports it, N03.0 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 N03.0 is sequenced first depends on the reason for the encounter.
- any associated kidney failure (N17-N19).
How long has N03.0 existed?
N03.0 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.
