Wiki colonoscopy w/ fluid aspiration but no u/s guidance

[katkins0121@yahoo.com]

I am having trouble finding the correct code to use for a colonoscopy with fluid aspiration w/ no ultrasound guidance. The exact wording for the colonoscopy reads:
"There was a dilute bright red liquid present throughout the colon;it did not appear to be blood. The fluid was aspirated and will be sent for occult blood."

Any advice??
