CPT 54231: Dynamic Cavernosometry with Pharmacologic Intracavernosal Injection
CPT code 54231 represents dynamic cavernosometry with intracavernosal injection of vasoactive agents to measure cavernosal pressures and assess penile blood flow during erection. This invasive diagnostic procedure is used to evaluate arterial insufficiency and venous leak as contributors to erectile dysfunction and can influence clinical decisions about vascular or surgical interventions. Nationally, accurate coding and documentation for this specialized vascular diagnostic test affect clinical care pathways and reimbursement for urology and vascular procedure settings.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, common billing modifiers reported in practice, and the role of 54231 in workups for erectile dysfunction. The publication summarizes benchmarks and billing considerations relevant to hospitals, ambulatory surgical centers, and urology clinics, and highlights where policy updates or payer-specific coverage criteria may influence utilization. Data not available in the input for some fields will be noted where applicable.
This piece is intended for coding professionals, revenue integrity staff, and clinical leaders seeking a national-level understanding of the procedure, its clinical purpose, and the billing context for 54231.
Billing Code Overview
CPT code 54231 describes dynamic cavernosometry with pharmacologic injection of the corpora cavernosa. This diagnostic vascular procedure measures intracavernosal pressure and evaluates blood flow dynamics during erection after injection of vasoactive agents to dilate penile blood vessels. The test is performed to quantify arterial inflow and identify the presence and severity of venous leakage contributing to erectile dysfunction.
Service type: Diagnostic vascular study with pharmacologic intracavernosal injection
Typical site of service: Hospital outpatient setting or ambulatory surgical center (specialized vascular laboratory or urology clinic with procedural capability)
Clinical & Coding Specifications
Clinical Context
A 52-year-old male presents to a urology clinic with a 2-year history of persistent erectile dysfunction not responsive to oral phosphodiesterase-5 inhibitors. Prior noninvasive testing (penile Doppler ultrasound) suggests arterial inflow is preserved but there is concern for veno-occlusive dysfunction (venous leakage). The urologist recommends dynamic cavernosometry and cavernosography to measure intracavernosal pressure during pharmacologically induced erection and to quantify the severity and pattern of venous leak.
The clinical workflow: the patient undergoes pre-procedure consent and medication review, baseline vital signs and penile Doppler review. In the procedure room, the provider places a small-gauge intracavernosal needle into the corpora cavernosa, measures resting intracavernosal pressure, then injects a vasoactive agent (eg, prostaglandin E1) to induce erection. Serial pressure measurements during erection are recorded. Dynamic cavernosography with radiographic contrast may follow to visualize venous outflow if indicated. Post-procedure monitoring includes hemostasis at the injection site, observation for priapism, and discharge instructions with analgesia and emergency contact information.
