- Billable — Valid for Submission
- Not Chronic
N08 is a billable ICD-10-CM diagnosis code for glomerular disorders in diseases classified elsewhere. 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. The code is a manifestation code that cannot be reported as the principal diagnosis. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Nephritis; nephrosis; renal sclerosis.
N08 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 N08: its own notes plus those printed at 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.
- Glomerulonephritis
- Nephritis
- Nephropathy
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
- glomerulonephritis, nephritis and nephropathy (in):
- antiglomerular basement membrane disease (M31.0)
- diabetes (E08-E13 with .21)
- gonococcal (A54.21)
- Goodpasture's syndrome (M31.0)
- hemolytic-uremic syndrome (D59.3-)
- lupus (M32.14)
- mumps (B26.83)
- syphilis (A52.75)
- systemic lupus erythematosus (M32.14)
- Wegener's granulomatosis (M31.31)
- pyelonephritis in diseases classified elsewhere (N16)
- renal tubulo-interstitial disorders classified elsewhere (N16)
- 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)

- 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 First
The underlying condition named in the note is sequenced before this code.
Code Also
A second code may be needed to fully describe the condition; the note gives no sequencing direction.

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 N08Overview
What is the ICD-10 code for glomerular disorders in diseases classified elsewhere?
The ICD-10-CM code for glomerular disorders in diseases classified elsewhere is N08. It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is N08 (Glomerular disorders in diseases classified elsewhere) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report glomerular disorders in diseases classified elsewhere on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does N08 group to?
On inpatient claims, glomerular disorders in diseases classified elsewhere maps 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 N08 be a principal diagnosis?
No. This is a manifestation code: glomerular disorders in diseases classified elsewhere describes the manifestation of an underlying disease rather than the disease itself, so the underlying condition is sequenced first.
Can N08 be reported with M31.0?
Not as a rule. The Excludes1 note on N08 lists "antiglomerular basement membrane disease (M31.0)". 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).
Does N08 risk-adjust for Medicare Advantage payment?
Not for Medicare Advantage: N08 maps to no category in the CMS-HCC V28 model. It still risk-adjusts in the ESRD (V21) category 141 (Nephritis).
