Top Medical Necessity Denial Reasons

  • The medical record documentation does not support the need for the specific quantity of supplies that exceeds the usual utilization amounts described. Refer to Local Coverage Determination L33822 & Policy Article A52464.
  • The medical record does not include documentation to support the beneficiary is testing at a frequency that corroborates the quantity of supplies dispensed (e.g., a specific narrative statement that adequately documents the frequency at which the beneficiary is actually testing or a copy of the beneficiary's log). Refer to Local Coverage Determination L33822 & Policy Article A52464.
  • Lancets, reagent strips, and other supplies necessary for the proper functioning of the device are also covered for patients for whom the device is indicated.
