Exhalation port with or without swivel used with accessories for positive airway devices, replacement only

HCPCS code

Name of the Procedure:

Exhalation Port with or without Swivel for Positive Airway Devices, Replacement (HCPCS A7045)


This procedure involves replacing the exhalation port, a crucial component of positive airway devices used for treating conditions such as sleep apnea. The exhalation port, which may include a swivel mechanism, ensures that exhaled air is properly released from the breathing circuit, enhancing comfort and effectiveness.


The primary goal is to maintain or improve the function of positive airway devices by ensuring the exhalation port is functioning correctly. This aids in treating conditions like sleep apnea by optimizing airflow and patient comfort.


  • Diagnosed sleep apnea
  • Malfunctioning or damaged exhalation port
  • Ineffective airflow or discomfort due to a worn-out exhalation port


  • No specific preparation required for replacing the exhalation port.
  • Ensure the positive airway device is clean and inspect other components for wear and tear.

Procedure Description

  1. Inspection: Evaluate the current exhalation port for damage or wear.
  2. Removal: Detach the old exhalation port from the positive airway device.
  3. Replacement: Attach the new exhalation port, ensuring a secure and proper fit.
  4. Testing: Turn on the device to check if the new exhalation port is functioning correctly.

Tools and Equipment:

  • New exhalation port (with or without swivel)
  • Basic cleaning supplies
  • Positive airway device-specific instructions


Typically, the replacement takes about 10-15 minutes.


This can be performed at home or in a healthcare provider’s office or outpatient clinic.


A healthcare provider may guide the initial replacement, but patients often perform subsequent replacements themselves.

Risks and Complications

  • Common Risks: Incorrect attachment leading to airflow issues.
  • Rare Risks: Allergic reactions to new materials, increased device noise.


  • Improved airflow and device functionality.
  • Enhanced comfort and treatment efficacy.
  • Reduced risk of infection or complications from a damaged port.


  • Immediate usability post-replacement.
  • Follow usual care guidelines for cleaning and maintaining the airway device.


  • Cleaning and reattaching the old exhalation port (if only mildly blocked or dirty).
  • Replacing the entire positive airway device if multiple components are failing.

Patient Experience

  • During the Procedure: Minimal discomfort, simple attachment and detachment processes.
  • After the Procedure: Immediate use of the device with improved functionality, potentially better sleep quality.

Pain management and comfort measures are generally not necessary due to the simplicity of the procedure.
