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.

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.

About the N00–N08 Code Range

Glomerular diseases affect the kidney’s filtering structures. This group includes kidney syndromes, blood or protein in the urine, inherited kidney disease, and glomerular disorders linked to diseases classified elsewhere.

The categories first separate the condition or finding. N00, N01, N03, and N05 distinguish acute, rapidly progressive, chronic, and unspecified nephritic syndromes. N02 addresses recurrent or persistent blood in the urine. N04 addresses nephrotic syndrome, which involves severe protein loss in the urine. N06 identifies protein in the urine alone with a specified structural change. N07 identifies hereditary kidney disease, while N08 identifies glomerular disorders in diseases classified elsewhere.

Within most categories, subdivisions distinguish the structural changes in the kidney’s filtering structures, including minor abnormalities, specific lesions, and C3 glomerulonephritis.
