Appeal type: DME/ Orthotics
Decision: Partially Favorable

 
We decided that the Plan has to pre-approve a ventilator for 3 months. We decided that the Plan does not 
have to pre-approve a ventilator for 6 months.  
 
You asked the Plan to pre-approve a ventilator (E0466). You say that the services are necessary. The Plan says 
that based on the documentation provided, coverage criteria have not been met. 
 
We decided that the Plan has to pre-approve a ventilator for 3 months.  
 
The Plan follows Medicare rules. Medicare rules say that ventilators may be covered when they are medically 
necessary for patients who have neuromuscular disease, thoracic restrictive diseases, and chronic respiratory 
failure due to chronic obstructive pulmonary disease (COPD). 
 
We asked our physician reviewer to carefully review the case file and apply the relevant Medicare rules to 
determine if the Plan was correct in denying the request to pre-approve a ventilator for 3 months. Our reviewer 
says that the services are medically necessary. Our physician reviewer found a home ventilator is not medically 
necessary, although the current device should be approved for an additional 3 months to allow time for 
transition to bilevel positive airway pressure (BiPAP). If this enrollee does have chronic carbon dioxide (CO2) 
retention, BiPAP with average volume-assured pressure support (AVAPS) should meet the enrollee's 
respiratory support needs. This has not been tried and demonstrated to fail. Medicare does not cover a home 
ventilator when used at settings that can be provided with BiPAP. The current device should be approved for an 
additional 3 months to allow time for transition to BiPAP with AVAPS. 
 
We looked at this physician's review, the file, and Medicare rules. Based on this information, we decided that 
Medicare rules for coverage of a ventilator for 3 months have been met. Therefore, we decided that the Plan 
has to pre-approve a ventilator for 3 months.  
 
We also decided that the Plan does not have to pre-approve a ventilator for 6 months.

If the Plan does not agree with our decision, they can ask us to open a case again. We only open a case again 
if we believe there was a mistake or if there is new information to review. The Plan has to show us the mistake 
and/or send us the new information. This does not happen often. If we decide to open the case again, we will 
send you a letter.
