Your doctor or other provider may be asked to provide a “Letter of Medical Necessity” to your health plan as part of a “certification” or “utilization review” process. This process allows the health plan to review requested medical services to determine whether there is coverage for the requested service.

You must be enrolled in a FEHB with a Health Savings Account (HSA), or have a spouse who is enrolled in a non-FEHB HSA-qualified HDHP and has an HSA, to enroll in a LEX HCFSA.

The money contributed to your FSAFEDS account is set aside before taxes are deducted, so in most cases you save about 30% on your Federal taxes. The average tax savings for a person earning $50,000 who contributes $2,000 into an FSA account is approximately $600.

The letter often includes relevant patient history, medical needs, and the duration of the treatment. You may need a letter of medical necessity for reimbursements of medical procedures, supplies, or equipment when you use a health savings account (HSA) or flexible spending account (FSA).

"Medically Necessary" or "Medical Necessity" means health care services that a physician, exercising prudent clinical judgment, would provide to a patient. The service must be: For the purpose of evaluating, diagnosing, or treating an illness, injury, disease, or its symptoms.

A Letter of Medical Necessity is the same as a Doctor's Statement. It's a letter written by your doctor, verifying that the medication you are buying with your Healthcare FSA is for a diagnosis, treatment, or prevention of a disease. This letter is required by the IRS for certain eligible expenses.
