Hi guest!
Great questions. Palmetto GBA - JM Part B released the following statement a few years back, and has reposted it to their site as April 2015 as well. Here is a link to the statement:
http://www.palmettogba.com/palmetto/providers.nsf/DocsCat/Providers~JM%20Part%20B~Browse%20by%20Topic~DMEPOS~96ESLW3556?openThe statement reads:
"HCPCS codes E0485 and E0486 describe oral devices or appliances used to reduce upper airway collapsibility, adjustable or non adjustable, prefabricated (E0485) or custom fabricated (E0486). These devices are typically used to treat obstructive sleep apnea. Both codes include all fitting and adjustment. These are codes reimbursed as Durable Medical Equipment by the Durable Medical Equipment Medicare Administrative Contractor (DME MAC). Medicare claims related to the fitting, initial/subsequent adjustments, and repairs of an oral device should be submitted to the appropriate DME MAC and not as Evaluation & Management (E/M) services to the AB MAC. Additionally, any radiological or other services performed in order to guide the adjustments of the oral device should not be submitted separately to the AB MAC, as the Medicare Program payment associated with HCPC Codes E0485 and E0486 already includes any required adjustments to ensure a properly fitted device.
After considerable internal study, and with agreement by dental experts at CMS Central Office, Palmetto GBA has confirmed that all services related to the codes - including initial patient evaluation, any required imaging, all fitting and post fabrication adjustments - are contained in the codes and payable only by the DME Medicare Administrative Contractor."
Hope this helps, have a great day!
