N08
Glomerular disorders in diseases classified elsewhere
N08 is a billable ICD-10-CM diagnosis code for glomerular disorders in diseases classified elsewhere. It is part of the FY2027 code set, effective October 1, 2026. The Alphabetic Index lists it under 39 entries. Its coding notes include a Code first instruction, a Code also instruction, 14 Excludes1 entries and 8 Excludes2 entries.
Code first
If the underlying condition listed here is present and known, sequence it first.
Code also
Two codes may be needed to describe the condition. This note gives no sequencing order.
Excludes1
Not coded here. The listed conditions generally should not be reported together.
- glomerulonephritis, nephritis and nephropathy (in):
- antiglomerular basement membrane disease (M31.0)

- renal tubulo-interstitial disorders classified elsewhere (N16)
Excludes2
Not included here. Both codes may be reported if the patient has both conditions.
Also from chapter/block level (8 notes)

Hospice: not accepted as primary
Not accepted as the principal diagnosis on a hospice claim (bill types 081x and 082x). The Integrated OCE returns an edit for this code.
Reason: Manifestation code. Report the underlying condition first (see the Code first note).
