The Certificate of Medical Necessity (CMN) for Oxygen is a required form that helps to document the medical necessity for oxygen therapy. It also documents other coverage criteria for the oxygen use. For payment on a home oxygen claim, the information in the supplier’s records or the patient’s medical record must be substantiated with the information in the CMN.

Completing this form is considered a service to the patient and any associated fees are included in the fee for service. Therefore, no fee is to be charged for completing a CMN.

According to the MLN Home Oxygen Therapy Booklet, a CMN can be submitted electronically, if:

  1. All privacy, security, and electronic signature rules and regulations published by CMS and the Department of Health and Human Services are followed.
  2. All of the following are identical to what is printed on the back of the hard copy
    1. Questions/wording
    2. Same sequence
    3. Same pagination
    4. Identical instructions/definitions
  3. Question sets are not combined and
  4. Hard copy of document is maintained on file

Requirements for submitting a CMN for Oxygen can be found in the MLN Booklet. This includes the time frames for recertification, blood gas study testing requirements, and physician visit requirements. Criteria that you must meet to furnish oxygen items and equipment for home use is also included for the Initial 36 months, months 37-60 and month 61 and after.
