To Whom It May Concern:

This letter serves as a Prescription and Letter of Medical Necessity for the above referenced patient for an insulin pump and related diabetic supplies.

The following prerequisites have been met:

  • Patient has demonstrated ability to self monitor blood glucose levels (>4X/day).
  • Patient is motivated to achieve and maintain improved glycemic control.
  • Patient/significant other is physically and intellectually able to operate the pump.
  • Patient demonstrates compliance with dietary and insulin regimen consisting of 3 injections per day and a total of 57 units per day.

Patient exhibits one or more of the following:

  • Glycosylated hemoglobin level of 7.8 %.
  • History of severe glycemic excursions
  • Wide fluctuations in blood glucose levels
  • Dawn phenomenon

Day to day variations in work schedule, mealtimes, and/or activity level, which confound the degree of regimentation required to self-manage glycemia with multiple daily injections. I certify that this information is correct. The insulin pump has been proven to lower HbA1c resulting in improved diabetes control [1], lower the risk of hypoglycemia [2], [3], reduce hospitalizations due to treatment of extremes in blood glucose [4], improve quality of life [5], prevent or delay diabetes complications and increase life expectancy [6].
