The ubiquitous use of A complication is not defined in relation to criteria; a complication is really just a disorder  is an unexpected condition, outcome, or adverse event due to another disorder or procedure.condition, procedure, or treatment. 

Concepts representing   For this reason, 116223007 |Complication (disorder)| is no longer active in the SNOMED CT terminology.  Instead, concepts of a disorder caused by another disorder, or for disorders following either medical or surgical procedures should be modeled using a parent of 64572001 |Disease (disorder)| or the appropriate intermediate primitive. Descriptions with the phrase "complication of" imply causality, and thus "due to" should be used in the description instead.  .  The word complication in an FSN should only be used when it can be verified that the caused disorder is an unintended or unexpected event. 

Conditions that are caused by another condition, but are not unexpected, should be modeled with a DUE TO relationship, but should not be named as complications.

For example, 10629511000119102 |Rhinitis of pregnancy (disorder)|

Conditions co-occurrent with another disorder but are not caused by the underlying disorder are co-morbidities and should not be modeled using the DUE TO relationship.

For example, 31563000 |Asymptomatic bacteriuria in pregnancy (finding)|
