ICD Code Q21.12

ICD code Q21.12 is a diagnosis code for patent foramen ovale, which is a small hole in the heart that did not close the way it should after birth.

1. Presence of a persistent opening in the interatrial septum at the location of the foramen ovale after birth

2. Echocardiographic evidence of a flap-like opening between the right and left atria

3. Detection of right-to-left or left-to-right shunting across the atrial septum, often identified with bubble study or color Doppler

4. Absence of other structural cardiac defects that would account for interatrial communication

5. May be asymptomatic or associated with cryptogenic stroke, migraine with aura, or decompression illness

6. No clinical signs of cyanosis or heart failure directly attributable to the defect

7. Confirmed diagnosis by a cardiologist or through cardiac imaging
