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).
Includes
Terms listed here further define or give examples of the conditions grouped under this code — they describe what the code covers, not a separate diagnosis.
- endophlebitis
- inflammation, vein
- periphlebitis
- suppurative phlebitis
