Letter of Medical Necessity Overview


The 'Letter of Medical Necessity' is a letter written after your wheelchair assessment to the insurance company paying for your wheelchair that justifies your need for the specific chair requested.  This letter is very descriptive and tells all about what equipment is recommended for you and why. Very often this letter must also include specialists' support and research to back up the medical need for a particular type of wheelchair. 


The clinician or therapist who did your wheelchair evaluation will write the letter of medical necessity, which is addressed to the third party payer or insurance company. Typically, your doctor who wrote your prescription for an assessment co-signs the letter as the 'ordering physician' to support the assessment's findings. 

In addition to the ordering physician, supporting documentation may come from several other specialists who are involved in your care. For example, if you are being treated for a wound or pressure sore, it is good to have documentation from your wound care specialist. This specialist can support your need for pressure relieving features on your wheelchair such as particular seat cushions, power tilt, custom armrests or a standing feature. 


This letter will be written after your wheelchair assessment and submitted to the third party, usually your insurance company, who is paying for the wheelchair.
