Hi Gaylen! D7951 – sinus augmentation with bone or bone substitutes via a lateral open approach can be crosscoded to: 21210 – graft, bone; nasal, maxillary, or malar areas *use -52 modifier for reduced services when bone is not obtained from the patient D4266 – guided tissue regeneration – resorbable barrier, per site There is not a direct crosscode available for this service, so if the medical insurer will not accept the “D” code on the medical claim (many will these days when they are medically necessary procedures), or you can use the code below and include narrative report to describe the procedure: 41899 – Unlisted procedure, dentoalveolar structures Now, as for the diagnostic code(s) – that will depend on why these services performed, or basically, what issues/condition(s) are being treated? For example, if there is atrophy of the maxilla (upper jaw): K08.24 – Minimal atrophy of maxilla K08.25 – Moderate atrophy of the maxilla K08.26 – Severe atrophy of the maxilla Hope this helps!
