O99.341 is a billable ICD code used to specify a diagnosis of other mental disorders complicating pregnancy, first trimester. A 'billable code' is detailed enough to be used to specify a medical diagnosis.


The ICD code O993 is used to code Chorea gravidarum

Chorea gravidarum is a rare type of chorea which presents with involuntary abnormal movement, characterized by abrupt, brief, nonrhythmic, nonrepetitive movement of any limb, often associated with nonpatterned facial grimaces. It is a complication of pregnancy which can be associated with eclampsia and its effects upon the basal ganglia. It is not an etiologically or pathologically distinct morbid entity but a generic term for chorea of any cause starting during pregnancy. It is associated with history of Sydenham's chorea. It mostly occurs in young patients; the average age is 22 years.

MeSH Code: D020150
