Present on Admission (POA)

Q28.2 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

Arteriovenous Malformations

Arteriovenous malformations (AVMs) are defects in your vascular system. Your vascular system is your body's network of blood vessels. It includes your:

An AVM is a snarled tangle of arteries and veins. They are connected to each other, with no capillaries. That interferes with the blood circulation in an organ.

AVMs can happen anywhere, but they are more common in the brain or spinal cord. Most people with brain or spinal cord AVMs have few, if any, major symptoms. Sometimes they can cause seizures or headaches.

AVMs are rare. The cause of AVMs is unknown, but they seem to develop during pregnancy or soon after birth. Doctors use imaging tests to detect them.

Medicines can help with the symptoms from AVMs. The greatest danger is hemorrhage. Treatment for AVMs can include surgery or focused radiation therapy. Because surgery can be risky, you and your doctor need to make a decision carefully.
