How to Make the R&N Determination

  2. Review clinical justification: Does the treating doctor's documentation explain why Saxagliptin is necessary for this specific injury?
  3. Assess duration: Is the prescribing duration within clinical guidelines?
  4. Check for alternatives: Have safer or more appropriate treatments been trialled first?
  5. Review interactions: Is Saxagliptin being combined with other medications that create additional risk?
  6. Document your determination: Record the R&N decision, rationale, and any actions taken in the claim file.
