ICD-10 Code for Glomerulonephritis

The ICD-10-CM code for glomerulonephritis is N05.9 — Unspecified nephritic syndrome with unspecified morphologic changes. This is the code the Alphabetic Index gives for glomerulonephritis with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).

BillableUnspecified

N05.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.

Which glomerulonephritis code should you use?

The Alphabetic Index lists 37 codes under Glomerulonephritis. Which one applies depends on the qualifier documented in the record — the type, site, cause, or associated condition. Find the qualifier below, then verify the code in the Tabular List before using it.
