The four DME MACs have revised a joint coding bulletin regarding the proper coding of custom fitted prefabricated orthoses versus off the shelf (OTS) orthoses. The revised bulletin reiterates the need for “substantial modification by a qualified individual” when billing for a custom fitted orthosis as opposed to an off the shelf orthosis. This is nothing new and is simply a re-statement of what has been existing policy for several years. The revised bulletin does add a new twist however. It states that if a HCPCS code is identified as prefabricated but does not have a corresponding code that describes the same product delivered as an OTS orthosis, it can only be used to bill orthoses that are supported by documentation of substantial modification to the orthosis performed by an individual with expertise in fitting. If this documentation does not exist, or the substantial modification was performed by a person without expertise in fitting, the orthosis must be billed with the appropriate miscellaneous code (L1499, L2999, L3999) and the supplier must indicate that the orthosis was delivered as an OTS item in the narrative field on the claim form.
The Medicare LCDs for spinal orthoses, AFOs/KAFOs, and knee orthoses have all been updated, effective May 1, 2015, to incorporate the language of the revised coding bulletin.
AOPA’s take on this issue is that this “clarification” represents a major shift in policy regarding the proper coding of custom fitted orthoses. If you are providing a custom fitted orthosis and expect to receive reimbursement from Medicare, you must ensure that documentation supports not only the need for whatever modifications were required to obtain a proper fit of the device but that the modifications were performed by a certified orthotist or other medical professional that is deemed qualified to perform the modifications. Failure to do so may lead to unnecessary and costly claim denials.
