At Yankee, a company called MOD Practice ( had a booth this year and provided dentists with these two coding updates:

D4355: You can now bill a D0150 or D0120 on the same date of service as a D4355. You can also bill a D0140 same day but your narrative MUST state that patients complaint is gum related and that the condition was caused by plaque and/or calculus.  You can NOT bill a D0180 in conjunction with a D4355 – it must be billed on a subsequent date after healing.

D4346: Used to report therapeutic treatment of patients with generalized moderate to severe gingival inflammation, with or without pseudo-pockets but exhibiting no bone loss.
