Oxygen Transmitting Concentrator

An Oxygen Transfilling Concentrator is a machine that separates room air into oxygen and nitrogen. The nitrogen is discarded, while the oxygen is stored, concentrated and delivered to you or your cylinder in a controlled dose at 91% to 95% purity.

Your unit may or may not be a single unit attached to the stationary concentrator.

A dual purpose concentrator will allow you to receive oxygen at home while you fill tanks at the same time. This will allow you to always have the portability you need at your convenience.

Medicare Information and Qualifications:

The patient must qualify for oxygen and then the physician will determine the type of equipment the patient will need.

General Coverage Guidelines

Home oxygen is covered and paid by Medicare if the following conditions are met:

  1. The patient has a severe lung disease or hypoxia-related symptoms that the physician has determined may improve with oxygen therapy.
  2. The patient’s blood gas study meets qualifying oxygen levels.
  3. The treating physician tried or considered alternative treatment measures and determined them to be ineffective.

Not Medically Necessary

  • For these situations, get an ABN to cover yourself, even if filing non-assigned.
  • Terminal illnesses that do not affect the respiratory system.
  • Angina pectoris in absence of hypoxemia.
  • Dyspnea without cor pumonale (or evidence of hypoxemia).
  • Severe peripheral vascular disease.

Summary: Certificates of Medical Necessity

To communicate qualifying medical necessity information to Medicare, claims must be billed with a Certificate of Medical Necessity. This is accomplished using the OMB approved form (CMS-484).
