Official Description

Insertion of penile prosthesis; inflatable (self-contained)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The insertion of a penile prosthesis is a surgical procedure aimed at treating erectile dysfunction, a condition where a man is unable to achieve or maintain an erection sufficient for satisfactory sexual performance. Specifically, CPT® Code 54401 refers to the insertion of an inflatable, self-contained penile prosthesis. This type of prosthesis allows for a more natural erection compared to non-inflatable options, as it can be inflated and deflated as needed. The procedure typically involves a penoscrotal approach, which is a surgical incision made at the junction of the penis and scrotum. This approach provides direct access to the necessary anatomical structures while minimizing trauma to surrounding tissues. The surgery involves careful dissection to identify the corpora cavernosa, the erectile tissues of the penis, and the placement of the prosthesis within these structures. The inflatable prosthesis consists of cylinders that are implanted into the corpora cavernosa, a pump that is placed in the scrotum, and a reservoir that is usually implanted in the abdomen. This setup allows the patient to control the inflation of the prosthesis, thereby restoring erectile function. The procedure is performed under sterile conditions and requires careful attention to detail to ensure proper placement and functionality of the device.

1. Indications

The insertion of an inflatable penile prosthesis is indicated for patients suffering from erectile dysfunction that has not responded to conservative treatments. The following conditions may warrant this surgical intervention:

  • Erectile Dysfunction - A persistent inability to achieve or maintain an erection suitable for sexual intercourse.
  • Peyronie's Disease - A condition characterized by the development of fibrous scar tissue inside the penis, causing curved, painful erections.
  • Severe Penile Trauma - Injury to the penis that results in erectile dysfunction due to damage to the erectile tissues.
  • Neurological Disorders - Conditions such as multiple sclerosis or spinal cord injuries that affect nerve signals necessary for achieving an erection.

2. Procedure

The procedure for the insertion of an inflatable penile prosthesis involves several detailed steps to ensure proper placement and functionality of the device:

  • Step 1: Incision A mid-raphe incision is made at the penoscrotal junction, allowing access to the underlying structures. The incision is carefully extended down to the dartos fascia, which is then divided to expose the operative field.
  • Step 2: Dissection The surgeon identifies the corpus spongiosum and continues dissection laterally to the urethra and spongiosum tissue until the corpora cavernosa are reached. This step is crucial for ensuring that the prosthesis can be properly placed within the erectile tissues.
  • Step 3: Placement of Stay Sutures Stay sutures are placed through the tunica albuginea, which is the fibrous envelope surrounding the corpora cavernosa, to secure each of the corpora cavernosa in place during the procedure.
  • Step 4: Corporotomy A corporotomy, or incision into the corpora cavernosa, is made between the stay sutures. This allows for the creation of spaces within the erectile tissues where the prosthesis will be inserted.
  • Step 5: Creation of Spaces The incisions are extended, and spaces are created within the corpora cavernosa to accommodate the inflatable prosthesis. This is done with careful attention to avoid damaging surrounding structures.
  • Step 6: Placement of the Prosthesis The inflatable prosthesis is then placed into the created spaces. This prosthesis consists of cylinders that will allow for inflation and deflation as needed.
  • Step 7: Pump Insertion A pouch is created in the sub-dartos tissue of the scrotum, where the pump component of the prosthesis is inserted. This pump is connected to the cylinders that were placed in the corpora cavernosa.
  • Step 8: Device Testing The device is cycled to ensure that it is functioning properly and to check for any potential leaks in the system.
  • Step 9: Closure Finally, the incisions are closed in layers, ensuring that the surgical site is secure and healing can begin.

3. Post-Procedure

After the insertion of the inflatable penile prosthesis, patients are typically monitored for any immediate complications. Post-procedure care includes managing pain and preventing infection. Patients may be advised to avoid sexual activity for a specified period to allow for proper healing. Follow-up appointments are essential to assess the functionality of the prosthesis and to ensure that the surgical site is healing appropriately. Patients will also receive instructions on how to operate the prosthesis to achieve optimal results.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
