What is LMN eligible?
There are specific products and services that may be what is considered dual-purpose (can serve a medical purpose an an alternative purpose), at which point, FSA users may be able to cover the cost with a Letter of Medical Necessity (LMN) from a physician. This letter must outline how a product/service is necessary to treat a legitimate medical condition and how long it will last. LMNs are approved on a case-by-case basis by benefits administrators, so be sure to inquire with them first before seeking out an LMN from a doctor. Some administrators may have other requirements besides an LMN as well. The LMN designation is there to let you know to inquire with your benefits administrator, as the specific expense may or may not be considered eligible.
