About the Y84 Code Range
Other medical procedures can cause an abnormal reaction or a later complication without a misadventure mentioned at the time of the procedure. Y84 groups these cases by the procedure involved.
The subdivisions distinguish cardiac catheterization (Y84.0), kidney dialysis (Y84.1), radiological procedures or radiotherapy (Y84.2), and shock therapy (Y84.3). They also separate fluid removal (Y84.4), insertion of a stomach or upper-intestine instrument (Y84.5), urinary catheterization (Y84.6), and blood sampling (Y84.7). Other medical procedures (Y84.8) and unspecified medical procedures (Y84.9) have separate subdivisions.
