*In ICD10 there are no codes specific for glomerulonephritis (GN) -- instead the various forms of that entity are included in the various codes for "Nephritic sydrome"
*Nephritic syndrome represents a class/category of renal diseases that are due to non-infectious inflammation of the glomerulus
**Though non-infectious, a classic cause of GN is immune-mediated and elicited by PRIOR infection by a variety of organisms, though Streptococci is the classic (so-called Post-strep GN) if using this code combine with [[Other specified infectious agents as the cause of diseases classified by other ICD10 code]]
**Although often ''primary'', i.e. the etiology is auto-immune, there are numerous other conditions that can cause GNs (e.g. post-infectious which is an immune-mediated problem and not due to the organism itself; in association with other immune disorders such as Lupus (lupus nephritis) and vasculitis; immune consequences of drug use such as iv heroin, others).  When the etiology is NOT primary, combine the cause with the appropriate Nephritic syndrome code.
*Regarding the various codes for nephritic syndrome ([[Nephritic syndrome, acute]], [[Nephritic syndrome, rapidly progressive]], [[Nephritic syndrome, chronic]], [[Nephritic syndrome, NOS]]) 
**They include
***glomerulonephritis
***nephritis
***other inflammatory glomerular diseases
**Don't get confused, another way to classify glomerular diseases is by what they look like under the microscope (e.g. minimal change, membranous, crecentic, etc) -- but in ICD10 these are all included within all the codes for nephritic syndrome.
*The difference between the various Nephritic syndrome codes is clinical onset and persistence:
**code [[Nephritic syndrome, rapidly progressive]] if and only if the primary or renal team label it as "rapidly progressive", as in "Rapidly progressive GN"
**if acute in presentation/onset, but they don't label it as "rapidly progressive", then use [[Nephritic syndrome, acute]]
**if stated by the teams to be chronic, then use [[Nephritic syndrome, chronic]]
**if nothing is said about it's onset or persistence, then use the wastebasket of [[Nephritic syndrome, NOS]]
*Important to distinguish the various Nephritic syndrome codes from [[Nephrotic syndrome]]


* a classic cause of GN (especially Nephritic syndrome, rapidly progressive is as an immune after-effect of Strep infection, so-called Post-strep GN). To code this we will add a new code B98, to be called [[Other specified infectious agents as the cause of diseases classified by other ICD10 code]] -- this new code, with the appropriate Streptoccus code, is then combined with the appropriate Nephritic syndrome code to get Post-strep GN
