D4921 vs D4999A

Our office uses Dentrix. I noticed there is a procedure code D4921 and D4999A both are listed as Gingival Irrigation. What is the difference?

D4921 is gingival irrigation per quadrant. D4999 is unspecified periodontal procedure by report. To me, it looks like your office entered both as irrigation.
