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.

  • underlying disease, such as:
  • amyloidosis (E85.-)
  • congenital syphilis (A50.0, A50.5)
  • congenital toxoplasmosis (P37.1)
  • infectious mononucleosis with liver disease (B27.0-B27.9 with fifth character 9)
  • schistosomiasis (B65.0-B65.9)

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).

  • alcoholic hepatitis (K70.1-)
  • alcoholic liver disease (K70.-)
  • cytomegaloviral hepatitis (B25.1)
  • herpesviral [herpes simplex] hepatitis (B00.81)
  • mumps hepatitis (B26.81)
  • sarcoidosis with liver disease (D86.89)
  • secondary syphilis with liver disease (A51.45)
  • syphilis (late) with liver disease (A52.74)
  • toxoplasmosis (acquired) hepatitis (B58.1)
  • tuberculosis with liver disease (A18.83)
