For anyone who needs supporting documentation:
CPT deleted code 69400 for Eustachian Tube inflation; transnasal; with catherterization beginning in 2015. The American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS), who is responsible for physician board certifications in ENT, states the following:
Deletion of three Eustachian tube codes (69400, 69401, and 69405). To report the work of 69400 or 69405 an unlisted code, 69799, is recommended. For 69401, the appropriate Evaluation and Management office visit code is recommended. For more, visit our coding corner to access the CPT for ENT on this topic.

Also, CPT states this in their parenthetical notes on page 427 of the 2017 CPT manual: [69400 has been deleted. To report, use 69799]
I would compare code 69799 for dilation with CPT 69420 since the code includes "Eustachian tube inflation."
Hope this helps!
