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

What 27648 covers

A physician, commonly a radiologist, places a needle or catheter into the ankle joint and injects contrast for an arthrogram. The injection precedes imaging used to assess the joint, such as radiography, CT, or MRI. Ankle arthrography may be requested to evaluate suspected cartilage or ligament injury, joint-surface abnormalities, or persistent symptoms after an ankle injury.

Select this code for the ankle-joint injection, not for an injection into another joint or for the imaging acquisition and interpretation. The record should identify the ankle, the clinical indication, and the intra-articular contrast injection. Report the imaging service separately when performed and documented; ankle arthrography imaging may be reported with 73615. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. 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.
