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

What 54231 covers

Dynamic cavernosometry is an invasive physiologic study used mainly by urologists to assess penile blood flow and pressure in men with erectile dysfunction when a vascular cause, such as impaired venous occlusion, is suspected. After medication induces an erection, the clinician infuses fluid into the corpora cavernosa and records pressure and flow measurements. The study may be performed in a urology office or facility setting.

Report 54231 when the clinician performs and documents the dynamic pressure-and-flow assessment, rather than an injection or imaging study alone. The record should support the indication, pharmacologic response, measurements, and clinical interpretation. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.
