When would you expect to see the D7951–sinus augmentation with bone or bonesubstitues code used?The procedure in question is: Placement of implant at site #3 with possibleindirect or direct sinus lifting.The Oral Surgeon documents that an “indirect sinus lift” was performed. Thank you. Brenda

D7951 is used for augmentation of the sinus cavity to increase alveolar height for reconstruction of edentulous portions of the maxilla. It includes obtaning the bone or bone substitute. Most common diagnosis code for this procedure would be 525.25 (moderate atrophy of maxilla) or 525.26 Severe atrophy of maxilla. If the doctor was placing an implant and performing and indirect sinus life it appears he has the correct code.
