Hello, I recently had extensive periodontal tissue grafts and would like to bill my medical insurance for the sedation and the plasma procedure that wasn”t covered under my dental insurance Is there a CPT equivalent for D7921? D7921 COLLECTION AND APPLICATION OF AUTOLOGOUS BLOOD CONCENTRATE PRODUCT D7921 reports the utilization of platelet rich plasma (PRP) to enhance the success of sinus grafting, ridge augmentation, osseous integration of implants, some endodontic procedures and some periodontal procedures. It can improve wound healing, tissue regeneration and can help augment bone graft procedures. Thanks for your help! Robin
