To whom it may concern:

This is a request for (choose one: appeal of your denial, pre-authorization, reimbursement) of a cooling vest for my patient, (patient name), who lives with (type) Multiple Sclerosis.  I prescribed this specialized garment to help manage and/or relieve the patient of the various symptoms induced or exacerbated by warm environments, including ____________________________________________________________________________________________________________________________.

(Patient name) has sought medical care due to heat-related symptoms on the following occasions: ____________________________________________________________________________________________________________________________________________.

The ability of heat to aggravate symptoms in patients with definitive MS is well-established.

Cooling studies as early as 1959 have revealed positive symptomatic outcomes for patients with MS. Cooling can result in objective clinical improvements in several functional systems of heat-sensitive MS patients, according to a clinical study performed by P.K. Coyle, M.D. and colleagues1. The effects of cooling reinstate energy in heat-blocked axons, allowing neural activity restoration, enabling remyelination to provide protection for axons from further degeneration; and potentially slowing the destructive progression of MS.

In a double-blind, randomized study to determine the effect of daily cooling garment use, 84 patients with definite MS received either high-dose or low-dose cooling for one hour per day for one month. The high-dose cooling group demonstrated a small but significant improvement in function and reported less fatigue on standardized, objective measures in comparison to the lower-dose group2.

Therefore, after careful consideration of (patient’s name)’s needs, functional capability and symptoms including (fill in specific details of relevant symptomatology and personal complaints), it is my conclusion that a cooling device would assist in improving (patient’s name)’s overall quality of life as well as functional abilities.

I hope this information is helpful to you and others, and encourages you to think about the beneficial outcome for (patient’s name) by (choose one: reconsidering/authorizing) (him/her) as a recipient of a cooling garment.

I look forward to, and appreciate, your prompt response in this pressing matter.

Very Truly Yours,
