D4240 GINGIVAL FLAP PROCEDURE, INCLUDING ROOT PLANING – FOUR OR MORE CONTIGUOUS TEETH OR TOOTH BOUNDED SPACES PER QUADRANT

A soft tissue flap is reflected or resected to allow debridement of the root surface and the removal of granulation tissue. Osseous recontouring is not accomplished in conjunction with this procedure. May include open flap curettage, reverse bevel flap surgery, modified Kirkland flap procedure, and modified Widman surgery. This procedure is performed in the presence of moderate to deep probing depths, loss of attachment, need to maintain esthetics, need for increased access to the root surface and alveolar bone, or to determine the presence of a cracked tooth or fractured root. Other procedures may be required concurrent to D4240 and should be reported separately using their own unique codes.
