Hi bgalloro! Great question. Some medical insurers seem to handle this differently, but typically you would report the code only once per arch. As an example, here are instructions provided by a medical insurer for this code: “CPT code 21248 is for partial restorations using implants involving less than half of the arch, while 21249 is for complete restorations involving more than half of the arch. Do not report these codes for each implant. Only report one instance of the applicable code, and report the number of implants placed in the “units” column.” Hope this helps!
