Respiratory Devices

 

DESCRIPTION

  1. Pulse oximetry technology is used routinely in clinical care settings to measure arterial oxygen saturation in real time. A pulse oximeter is a machine that attaches to a fingertip, toe, ear, or other site to estimate oxygen levels in the body. The machine uses light energy to “look” at the hemoglobin protein in red blood cells, and find out how much of the hemoglobin proteins have oxygen in them. It is frequently used in emergency rooms, urgent care centers, intensive care units, oxygen clinics, hospitals, and other clinical settings. Health care professionals interpret the data obtained from the device and determine the appropriate treatment for the patient. Like most medical measurement devices, this machine require special evaluation to make sure it is working properly, and not giving false information.
  2. A spacer (also known as a chamber, reservoir, Aerochamber®, InspirEase®) is a tube device which attaches to a metered dose inhaler (MDI) for asthma treatment. Some spacers have small masks attached. The asthma medicine is first sprayed into the spacer; then the patient inhales it into the lungs. This drug delivery device helps send more medicine into the lungs in some patients.
  3. A peak flow meter is a device that measures breathing capacity and is used by asthmatics or other patients with breathing difficulties:
  • This is measured by forcibly blowing into a plastic tube, indicating the “peak flow” of air. If the reading is lower than usual, it may be an early sign that breathing is about to worsen. The National Institute of Health (NIH) recommends use of this device for many asthmatics. Patients should also have an action plan from their physician based on peak flow readings.
  • Some peak flow meters have special attachments to record measurements, which can be displayed on a computer. The AirWatch® system is considered by the U.S. Food and Drug Administration (FDA) to be a peak flow meter. Compared to regular plastic tube peak flow meters, the AirWatch® meter has electronic parts, and the information from readings can be downloaded into a computer. The AirWatch® meter can also check another reading, FEV1, which is a different measurement of breathing.

Indications for Oscillatory Devices for the Treatment of Cystic Fibrosis and Other Respiratory Disorders are discussed in a separate policy.

Indications for Oxygen Therapy are discussed in a separate policy.

Indications for Inhaled Nitric Oxide as a Treatment of Hypoxic Respiratory Failure are discussed in a separate policy.

Indications for the Measurement of Exhaled Nitric Oxide in the Diagnosis and Management of Asthma and Other Respiratory Disorders are discussed in a separate policy.

Indications for Home Apnea Monitors are discussed in a separate policy.

Indications for the treatment of Sleep Disorders are discussed in a separate policy.

Pulse Oximetry for Home Use is discussed in a separate policy.

 

POLICY

 The following respiratory devices are considered medically necessary:
  • Spacers for use with metered dose inhalers (MDIs)
  • Peak flow meters for patients with respiratory disorders

For coverage criteria of pulse oximetry in the home setting,  refer to the Pulse Oximetry for Home Use medical policy.

When noninvasive ear or pulse oximetry testing is performed in a professional's office, it is considered integral to the professional's medical or surgical care. Therefore, the device is not a distinct or separate service, and separate payment will not be made for the pulse oximeter in these instances.

Computerized peak flow meters (including AirWatch®). Special features such as computerized recording devices are considered convenience enhancements and are not eligible for additional coverage.

 

POLICY EXCEPTIONS

None

 

POLICY GUIDELINES

The coverage guidelines outlined in the Medical Policy Manual should not be used in lieu of the Member’s specific benefit plan language.

9/24/2009: Description Section revised to include links to Oscillatory Devices for the Treatment of Cystic Fibrosis and Other Respiratory Disorders Medical Policy, Oxygen Medical Policy, Inhaled Nitric Oxide as a Treatment of Hypoxic Respiratory Failure Medical Policy, Measurement of Exhaled Nitric Oxide in the Diagnosis and Management of Asthma and Other Respiratory Disorders Medical Policy, Home Apnea Monitors Medical Policy, Sleep Disorders Medical Policy, and Aerosolized Antibiotics as a Treatment of Chronic Sinusitis Medical Policy. Information on Cystic fibrosis and oscillatory devices removed. Policy Statement Section revised to remove oscillatory devices information. Coding Section revised to remove ICD9 Diagnosis code 277.0 from Covered Codes Table, and revised to remove HCPCS codes A7025, A7026, E0481, E0483, E0484, S8185 from Non-Covered Codes Table. Verbiage added to Covered Codes Table, "* Some covered procedure codes may have multiple descriptions. Coverage will only be made for covered codes when used for services outlined within the policy statement section". Verbiage added to Non-Covered Codes Table, "*This is not an all inclusive list of non-covered procedure codes."
