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.

How the 54231 rate is calculated

Each of 54231’s three RVUs is multiplied by a geographic index (GPCI) for the payment locality, added up, and multiplied by the conversion factor. Drag the indexes or enter a ZIP to see what moves the rate.

How to choose

54230Cavernosography
54230 is the contrast-imaging procedure for cavernosography. Use 54231 for dynamic pressure and flow measurements; both may be performed during the same diagnostic evaluation.
54235Penile injection
54235 describes injection of a therapeutic agent into the corpora cavernosa. It does not represent the dynamic pressure-and-flow assessment reported with 54231.
54240Penile plethysmography
54240 is penile plethysmography, a separate method of evaluating erectile response. Choose 54231 when the clinician performs invasive cavernosal pressure and flow measurements.
54250Nocturnal erection testing
54250 evaluates nocturnal penile tumescence and rigidity. It is distinct from the induced, invasive hemodynamic study reported with 54231.

54231 billing questions

How is 54231 different from cavernosography?

54231 reports dynamic pressure and flow measurements during a pharmacologically induced erection. Cavernosography uses contrast imaging to show penile venous anatomy and may be performed with cavernosometry.

Does the pharmacologic injection alone support 54231?

No. The service involves a dynamic hemodynamic assessment, not simply injecting an agent into the corpora cavernosa.

What documentation supports reporting this code?

Document the clinical reason for the study, the pharmacologic response, the pressure and flow measurements, and the clinician’s interpretation of the findings.

Should modifier 50 be appended?

No. CMS identifies bilateral adjustment as inappropriate for this code’s descriptor and anatomy.

How does the multiple-procedure reduction affect payment?

When 54231 is performed with other procedures in the same session, the highest-valued procedure is paid in full and the other procedure or procedures are subject to the standard 50% reduction.

Can an assistant or co-surgeon be reported?

Medicare does not pay an assistant at surgery for this code, and co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
