question
Coding of sequela generally requires two codes sequenced in the following order: _____________________________________________.
answer
the condition or nature of the sequela is sequenced first. The sequela code is sequenced second.
question
Manifestation
answer
Signs and/or symptoms of an underlying disease, not the disease itself, and therefore, cannot be a principal diagnosis.
question
Excludes 1
answer
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. If two conditions are not related to one another, it is possible to report both codes despite the presence of an Exclude note 1. Ex: Mental disorder (F01-F99) cannot be assigned with the R40-R46 codes but if dizziness (R42) is not component if mental health condition then we can code it separately.
question
Excludes2
answer
A type 2 Excludes note represents "Not included here." An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology.
