Do all products require a Letter of Medical Necessity?Updated 9 days ago

No. Some products are auto-substantiated, meaning they are pre-approved for HSA/FSA purchase without a LOMN (for example, sunscreen SPF 15+, first aid supplies, and certain medical-grade skincare products). For these items, you simply pay with your HSA/FSA card at checkout — no consultation is required. Flex automatically determines which products need a LOMN and which do not.
