Oral interface used with positive airway pressure device, each

HCPCS code

Name of the Procedure:

Oral Interface Used with Positive Airway Pressure Device (HCPCS A7044)


This procedure involves using a special oral device that connects to positive airway pressure (PAP) machines, which help people with breathing disorders. The oral interface ensures consistent airflow through the mouth, keeping the airways open during sleep or periods of rest.


The primary goal is to treat sleep apnea and other similar conditions where the airways collapse or become obstructed during sleep. By using an oral interface with a PAP device, patients can maintain open airways, ensuring proper breathing and alleviating symptoms like snoring, daytime fatigue, and interrupted sleep patterns.


  • Sleep apnea (obstructive or central)
  • Chronic snoring
  • Respiratory insufficiency during sleep
  • Conditions requiring consistent positive airway pressure


  • Patients may need to undergo a sleep study to confirm the diagnosis of sleep apnea.
  • Follow instructions on medications, typically no specific fasting or adjustments needed.
  • Ensure the PAP device and oral interface are properly fitted by a healthcare provider.

Procedure Description

  1. Initial Assessment: A healthcare provider will evaluate the patient's condition and fit the oral interface to ensure comfort and effectiveness.
  2. Device Setup: The oral interface is connected to the PAP machine.
  3. Usage Instructions: Patients are shown how to correctly wear the interface and adjust the PAP device settings.
  4. Monitoring: Patients may be monitored initially to check efficacy and comfort.


The fitting process and initial usage instruction typically take about 1-2 hours. The usage of the device is continuous during sleep hours.


  • Sleep clinic
  • Outpatient clinic
  • Home (after initial setup and instruction)


  • Sleep specialist or pulmonologist
  • Respiratory therapist
  • Medical technician or nurse

Risks and Complications

  • Common: Dry mouth, slight discomfort, adjustment period
  • Rare: Mouth sores, dental issues, significant discomfort
  • Management: Regular follow-ups to adjust fit and settings, address any discomfort or side effects.


  • Improved sleep quality
  • Reduction or elimination of sleep apnea symptoms
  • Enhanced daytime alertness and cognitive function
  • Long-term cardiovascular health benefits


  • No actual recovery period as this is a nightly usage device.
  • Regularly clean the oral interface and PAP device.
  • Follow up with a healthcare provider to ensure ongoing efficacy and comfort.


  • Continuous Positive Airway Pressure (CPAP) with a nasal or full-face mask
  • BiPAP (Bilevel Positive Airway Pressure)
  • Oral appliances not connected to PAP devices
  • Surgical options in severe cases
  • Pros and cons depend on patient comfort, severity of the condition, and specific medical recommendations.

Patient Experience

  • Initial discomfort is common but usually resolves within a few weeks.
  • Patients might experience improved sleep almost immediately.
  • Pain management typically not required, but comfort measures include ensuring a proper fit and regular device adjustment follow-ups.
