Combination oral/nasal mask, used with continuous positive airway pressure device, each

HCPCS code

Name of the Procedure:

Combination Oral/Nasal Mask, used with Continuous Positive Airway Pressure Device (CPAP), each
Common name(s): Full-face CPAP mask, CPAP combination mask
Technical/Medical term: A7027


A combination oral/nasal mask is a device used with a Continuous Positive Airway Pressure (CPAP) machine to help individuals with sleep apnea maintain an open airway during sleep. The mask covers both the mouth and the nose, allowing for continuous airflow.


Medical conditions or problems it addresses:

  • Obstructive sleep apnea (OSA)
  • Central sleep apnea
  • Complex sleep apnea syndrome

Goals or expected outcomes:

  • Prevent airway collapse
  • Improve sleep quality
  • Reduce sleep apnea symptoms such as snoring and daytime sleepiness


Specific symptoms or conditions warranting the procedure:

  • Frequent loud snoring
  • Episodes of breathing cessation during sleep
  • Excessive daytime sleepiness
  • Awakening with a dry mouth or sore throat
  • Morning headache

Patient criteria or factors:

  • Diagnosed with sleep apnea via a sleep study
  • Inadequate response to other forms of treatment such as lifestyle changes or oral appliances


Pre-procedure instructions:

  • No specific fasting requirements
  • Review proper mask fitting techniques and CPAP machine operation
  • Adjust medications if necessary, as advised by the healthcare provider

Diagnostic tests or assessments:

  • Polysomnography (sleep study) to diagnose sleep apnea
  • CPAP titration study to determine optimal pressure settings

Procedure Description

Step-by-step explanation:

  1. Fit the mask: The patient will place the combination oral/nasal mask over their mouth and nose.
  2. Adjust straps: Secure the mask with headgear straps to ensure a comfortable and air-tight seal.
  3. Connect to CPAP device: Attach the mask to the CPAP machine via a hose.
  4. Set pressure: The CPAP device will deliver a continuous stream of air at a prescribed pressure to keep the airway open.

Tools, equipment, technology used:

  • Combination oral/nasal mask (A7027)
  • CPAP machine
  • Hose

Anesthesia or sedation: Not applicable


How long the procedure typically takes: Fitting and setup typically take 30 minutes; usage is continuous throughout the night during sleep.


Where performed: Home setting, sleep clinics for initial setup, or follow-up adjustments.


Healthcare professionals involved:

  • Sleep specialist physician
  • Respiratory therapist
  • CPAP technician

Risks and Complications

Common risks:

  • Mask discomfort
  • Skin irritation or pressure sores
  • Dry mouth or nasal passages

Rare risks:

  • Claustrophobia
  • Air leaks
  • Conjunctivitis due to air leakage into the eyes

Possible complications and management:

  • Regular adjustments for proper fit
  • Humidifier attachment to CPAP for dryness
  • Skin barrier creams for irritation


Expected benefits:

  • Improved sleep quality
  • Reduced or eliminated episodes of apnea
  • Enhanced daytime alertness
  • Decreased risk of hypertension, heart disease, and stroke

How soon benefits might be realized: Improvements can often be noticed within a few days of consistent use.


Post-procedure care:

  • Regular cleaning of the mask and CPAP components
  • Periodic visits to the sleep specialist for follow-up and adjustments

Expected recovery time: No recovery time; ongoing nightly use

Restrictions or follow-up appointments: Regular follow-ups to ensure proper CPAP settings and mask fit.


Other treatment options:

  • Lifestyle changes (e.g., weight loss, positional therapy)
  • Oral appliances
  • Surgery (e.g., UPPP, mandibular advancement)

Pros and cons of alternatives:

  • Lifestyle changes are non-invasive but may be insufficient for severe cases
  • Oral appliances are less cumbersome but may not be as effective
  • Surgery offers permanent solutions but comes with surgical risks

Patient Experience

What the patient might feel or experience:

  • Initial discomfort or adjustment period to wearing the mask
  • Reduced symptoms of sleep apnea and more restful sleep

Pain management and comfort measures:

  • Proper mask fitting to minimize discomfort
  • Use of humidification to alleviate dryness
  • Gradual acclimatization to using the CPAP mask through practice and patience
