- Billable — Valid for Submission
- Chronic Condition
N06.0 is a billable ICD-10-CM diagnosis code for isolated proteinuria with minor glomerular abnormality. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 698 through 700. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Nephritis; nephrosis; renal sclerosis and Proteinuria.
N06.0 does not risk-adjust for Medicare Advantage under the CMS-HCC V28 model. It still risk-adjusts in the ESRD (V21) category 141 for payment year 2027.

Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to N06.0: its own notes plus those printed at N06, block N00-N08, and Chapter 14. A note printed at a category, block or chapter applies to every code under it.
Applicable To
Conditions this code is used for: synonyms of the title or, for "other specified" codes, the conditions assigned to it. The list is not exhaustive.
- Isolated proteinuria with minimal change lesion
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
- Proteinuria not associated with specific morphologic lesions (R80.0)
- hypertensive chronic kidney disease (I12.-)
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may 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)

Patient EducationClinical
Kidney Diseases
You have two kidneys, each about the size of your fist. They are near the middle of your back, just below the rib cage. Inside each kidney there are about a million tiny structures called nephrons. They filter your blood. They remove wastes and extra water, which become urine. The urine flows through tubes called ureters.

Questions About N06.0Overview
What is the ICD-10 code for isolated proteinuria with minor glomerular abnormality?
The ICD-10-CM code for isolated proteinuria with minor glomerular abnormality is N06.0 (sometimes written as N060). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is N06.0 (Isolated proteinuria with specified morphological lesion) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report isolated proteinuria with minor glomerular abnormality on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does N06.0 group to?
When isolated proteinuria with minor glomerular abnormality is the principal diagnosis on an inpatient stay, it groups to MS-DRG 699, 698, 700, with relative weights from 0.6740 to 1.6400 depending on complications. Higher weights mean higher Medicare reimbursement.
Can N06.0 be reported with R80.0?
Not as a rule. The Excludes1 note at N06, which applies to N06.0, lists "Proteinuria not associated with specific morphologic lesions (R80.0)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
What is the ICD-9 equivalent of N06.0?
Under the General Equivalence Mappings, isolated proteinuria with minor glomerular abnormality converts to ICD-9-CM 583.89 (nephritis NEC). The mapping is approximate, so confirm the match fits the documentation.
Does N06.0 risk-adjust for Medicare Advantage payment?
Not for Medicare Advantage: N06.0 maps to no category in the CMS-HCC V28 model. It still risk-adjusts in the ESRD (V21) category 141 (Nephritis).
