Hi! There is not particular dedicated CDT code for all laser therapy in dentistry. Laser procedures are typically billed under existing CDT codes that describe the specific procedure performed, regardless of whether a laser was used. Example: laser-assisted perio therapy can be billed under D4240, D4241, D4260, or D4261, depending on the specific tx. Some practices will use D4999 "unspecified periodontal procedure, by report" for laser therapy in perio cases.
