SAMPLE LETTER OF MEDICAL NECESSITY
Payers may require prior authorization or supporting documentation in order to process and
cover a claim for the requested therapy. A prior authorization allows the payer to review the
reason for the requested therapy and to determine medical appropriateness. A patient-specic
letter of medical necessity will help to explain the physician’s rationale and clinical decision
making in choosing a therapy. Please see page 2 for a sample letter of medical necessity with
llable elds that can be customized based on your patient’s medical history and demographic
information and then printed. Please note that some payers may have specic forms that must be
completed in order to request prior authorization or to document medical necessity.
