Official Description

Penile plethysmography

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Penile plethysmography is a diagnostic procedure that utilizes a plethysmograph, a specialized device designed to measure blood flow in various parts of the body, specifically focusing on the penis in this context. This procedure is primarily employed to assess erectile dysfunction, a condition characterized by the inability to achieve or maintain an erection sufficient for satisfactory sexual performance. There are two main types of plethysmography used in this evaluation: the volumetric air chamber type and the circumferential transducer type. The volumetric air chamber type involves placing a chamber over the penis, where the device measures the amount of air displaced as the penis becomes erect, providing quantitative data on erectile function. Alternatively, the circumferential transducer type employs a rubber ring filled with mercury or indium/gallium, which is positioned around the shaft of the penis. This method measures changes in diameter as the penis engorges with blood during an erection. After the procedure, the physician analyzes the collected data and generates a written interpretation of the results, which aids in diagnosing the underlying causes of erectile dysfunction.

1. Indications

Penile plethysmography is indicated for the evaluation of erectile dysfunction, which may arise from various underlying conditions. The following are specific indications for performing this procedure:

  • Erectile Dysfunction The primary indication for penile plethysmography is to diagnose erectile dysfunction, which can be caused by psychological, neurological, or vascular issues.
  • Assessment of Vascular Function This procedure may be utilized to assess vascular function in patients suspected of having vascular-related erectile issues.
  • Evaluation of Penile Blood Flow It is also indicated for evaluating penile blood flow to determine the adequacy of blood supply necessary for achieving and maintaining an erection.

2. Procedure

The procedure for penile plethysmography involves several key steps to ensure accurate measurement of erectile function. The following outlines the procedural steps:

  • Step 1: Patient Preparation The patient is prepared for the procedure by explaining the process and ensuring they are comfortable. The physician may ask the patient to refrain from sexual activity prior to the test to ensure accurate results.
  • Step 2: Device Selection Depending on the specific needs of the assessment, either the volumetric air chamber type or the circumferential transducer type of plethysmograph is selected for use. The choice of device may depend on the physician's preference or the specific clinical scenario.
  • Step 3: Placement of the Device For the volumetric air chamber type, the device is placed over the patient's penis. In the case of the circumferential transducer type, the rubber ring filled with mercury or indium/gallium is positioned around the shaft of the penis. Proper placement is crucial for obtaining accurate measurements.
  • Step 4: Measurement of Blood Flow As the patient becomes aroused, the device measures either the air displacement (in the volumetric air chamber type) or the changes in diameter (in the circumferential transducer type) as the penis engorges with blood. This data is collected in real-time to assess erectile function.
  • Step 5: Data Analysis After the measurements are taken, the physician reviews the results obtained from the plethysmography. This analysis is critical for understanding the patient's erectile function and identifying any underlying issues.
  • Step 6: Interpretation of Results Finally, the physician provides a written interpretation of the results, summarizing the findings and offering insights into the patient's erectile health. This report may be used to guide further diagnostic or therapeutic interventions.

3. Post-Procedure

Post-procedure care for penile plethysmography typically involves providing the patient with information regarding the results and any necessary follow-up actions. The physician will discuss the findings from the plethysmography and may recommend additional tests or treatments based on the results. Patients are generally advised to resume normal activities following the procedure, as there are no significant recovery requirements. However, any concerns or unusual symptoms should be reported to the physician promptly. The written interpretation of the results will be documented in the patient's medical record for future reference and ongoing management of erectile dysfunction.

59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
