HCPCS code

Name of the Procedure:

Nasal Pillows for Combination Oral/Nasal Mask, Replacement Only, Pair (HCPCS Code A7029)


Nasal pillows are soft cushions that fit directly into the nostrils and are a part of a combination oral/nasal mask used in CPAP (Continuous Positive Airway Pressure) therapy for patients with sleep apnea. This procedure involves replacing the worn-out nasal pillows with a new pair.


The nasal pillows are designed to improve air delivery for patients using a combination oral/nasal mask as part of their CPAP therapy. Replacing worn-out nasal pillows ensures effective and comfortable CPAP therapy, helping to manage sleep apnea symptoms and improve sleep quality.


  • Patients diagnosed with obstructive sleep apnea (OSA) and using a CPAP machine with a combination oral/nasal mask.
  • Signs of wear and tear, discomfort, or reduced effectiveness in the existing nasal pillows.


  • No specific preparation is required for the nasal pillow replacement.
  • Patients should ensure their CPAP machine and mask are clean and functioning properly.

Procedure Description

  1. Removal of Old Pillows: Gently remove the worn-out nasal pillows from the existing combination oral/nasal mask.
  2. Inspection: Check the mask components for any damage or wear.
  3. Insertion of New Pillows: Attach the new nasal pillows securely to the mask, ensuring a proper fit.
  4. Testing: Connect the mask to the CPAP machine and test for air leaks. Adjust if necessary for comfort and effectiveness.


The procedure typically takes about 5-10 minutes.


This procedure is usually performed at home by the patient or a caregiver. It can also be done in a sleep clinic or doctor's office if assistance is needed.


  • No healthcare professionals are required for this simple replacement, but CPAP technicians, respiratory therapists, or sleep clinic staff may assist if needed.

Risks and Complications

  • Common risks: Minor discomfort or irritation in the nostrils.
  • Rare risks: Nasal congestion, nosebleeds, or skin irritation around the nose. These can be managed by adjusting the fit or using proper skin care products.


  • Immediate improvement in the effectiveness of CPAP therapy.
  • Increased comfort, leading to better adherence to therapy and improved sleep quality.


  • No recovery period is required.
  • Patients should monitor for any discomfort or air leaks and make adjustments as necessary.
  • Follow-up with a healthcare provider if issues persist.


  • Full face masks or nasal masks, depending on patient preference and comfort.
  • Pros: Alternatives may provide a better fit for some face shapes or reduce nasal irritation.
  • Cons: Full face masks can be bulkier and less comfortable for some patients compared to nasal pillows.

Patient Experience

  • The process is straightforward and usually comfortable.
  • Minor adjustments may be needed to ensure a proper fit.
  • Regular replacement of nasal pillows is recommended every few months or as needed to maintain therapy effectiveness and comfort.
