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

What 50390 covers

A clinician uses a needle through the skin to aspirate fluid from, or inject material into, a renal cyst or the renal pelvis. The service may be performed by a urologist or interventional radiologist in a procedure room, imaging suite, or hospital setting. A typical clinical reason is evaluating or relieving symptoms from a fluid-filled renal cyst; the target and purpose of the procedure determine whether this code fits.

Report the service for the percutaneous needle procedure, with documentation identifying the renal target, approach, and work performed. This code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, Medicare pays the highest-valued procedure in full and reduces the others. For bilateral reporting with modifier 50, Medicare pays 150%. Medicare does not pay an assistant at surgery for this procedure; co-surgeons and team surgery are not permitted.
