Clinical notes
Code first
This code represents a manifestation of an underlying disease. Coding convention requires the underlying (etiology) code to be sequenced first, with this code listed second.
Excludes1 (not coded here)
An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).
- glomerulonephritis, nephritis and nephropathy (in):
- antiglomerular basement membrane disease (M31.0)
- diabetes (E08-E13 with .21)
- gonococcal (A54.21)
- Goodpasture's syndrome (M31.0)
- hemolytic-uremic syndrome (D59.3-)
