Glomerular diseases (N00-N08) ICD-10-CM
The N00–N08 section covers glomerular diseases with 120 ICD-10-CM diagnosis codes, of which 107 are billable in fiscal year 2026. The section is organized into the 9 code ranges listed below.
Code Also
A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
- any associated kidney failure N17
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- hypertensive chronic kidney disease I12

About the N00–N08 Code Range
ICD-10 codes N00 through N08 cover a group of kidney disorders affecting the glomeruli, the filtering units of the kidneys. These codes are specifically used to classify various glomerular diseases, including acute, chronic, hereditary, and nephrotic syndromes with detailed descriptions of the morphological changes involved.
This range includes codes for acute nephritic syndrome (N00) with subtypes defined by different glomerular abnormalities such as minor abnormalities, focal and segmental lesions, membranous glomerulonephritis, and crescentic glomerulonephritis. Codes like N01 describe rapidly progressive nephritic syndrome, which is a quickly worsening kidney inflammation with similar detailed morphologies. Recurrent and persistent hematuria (N02) codes address ongoing or repeated blood in urine linked to specific glomerular lesions. Chronic forms (N03) and nephrotic syndrome (N04) are also covered with distinctions based on types of glomerular damage, from minor abnormalities to dense deposit disease or membranoproliferative lesions. The codes include hereditary nephropathies (N07) with various glomerular patterns and glomerular disorders secondary to other diseases (N08). Importantly, many synonyms such as "minimal change disease," "focal segmental glomerulosclerosis," and "IgA nephropathy" are tied to specific codes to guide accurate classification of these complex kidney conditions.
