OTS Orthotics-Minimal Self Adjustment

In today’s orthotic world we are getting blasted with the term “OTS-Minimal Self Adjustment.” By now most of us are up to speed on its definition and scope, but just for a refresher, here you go: CMS regulations 42 CFR 414.402 define Minimal Self-Adjustment (MSA) to mean an adjustment that the beneficiary, caretaker for the beneficiary, or a supplier of the device can perform and that does not require the services of a certified Orthotist (that is, an individual who is certified by the American Board for Certification in Orthotics and Prosthetics, Inc., or by the Board for Orthotist/Prosthetist Certification) or an individual who has specialized training.

OTS codes that fall under these guidelines include, but are not limited to L0120 through L4398 and K-Codes-K0901 and K0902. Please refer to the Medicare Fee for Service website at www.cms.gov for a complete list. It is important to note that in some cases there are two codes in the HCPCS that may both describe a particular prefabricated orthotic product. One code is allocated to the device that is designated as Off-the-Shelf (OTS) and a second for when the device is furnished for custom fitting. In these cases, the code that describes a custom fitted orthotic cannot be used unless the custom fitting has been performed and the supplier is in compliance with Appendix C of the DMEPOS quality standards. This is also the case for any code for a prefabricated orthotic that requires more than minimal self-adjustment and requires expertise in fitting or customizing.
