Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 27278 covers

A surgeon uses a percutaneous approach to fuse the sacroiliac joint by placing implant(s) within the joint without a transfixation device. The procedure may be considered for selected patients with symptomatic SI joint conditions, such as degenerative joint disease or SI joint dysfunction. Orthopedic and spine surgeons typically perform it in an operating room or other procedural setting, using image guidance to place the implants.

Choose this code when the operative report supports the intra-articular implant technique; a transfixation-device approach is reported with a different code. Image guidance is included. Documentation should identify the treated joint, approach, implant placement, and arthrodesis performed. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
