nasal "lavage"

One of our doctors "lavages" the sinus' to check for pertussis, he inserts a tube into the nasal cavity irrigates with saline then aspirates the contaminated saline back out and sends it off to the lab for diagnosis. Is there such a code for doing this procedure I did find 31000-31002 Lavage by cannulation however that seems more involved that what our physician is doing, any ideas, Thanks

30210 maybe?

The physician displaces mucopurulent secretions (pus and mucous) from sinuses by gravity replacement with a second liquid. This therapy is effective for the ethmoid and sphenoid sinuses. While lying supine, the patient's head is hyperextended. The nose is filled with isotonic saline solution. The physician closes one nostril and applies suction to the other nostril. The patient repeats vowels or words (phonates), elevating the soft palate and creating negative pressure. While the patient is phonating, the physician suctions the nostril. The saline solution enters the sinus, displacing the secretions of the sinuses. The secretions are suctioned from the nostril.

I believe the provider is having the patient hang their head over a sink and pushes saline thru the sinus
