Diagnosis requirements for glucagon-like peptide-1 (GLP-1) agonists:

Effective June 1, 2023, Humana will require pharmacies to enter a diagnosis code for a medically accepted indication supplied by the prescriber when processing a prescription claim for a GLP-1 receptor agonist for Humana-covered patients. Beginning on the above date, please include the diagnosis on the GLP-1 prescription to minimize delays in dispensing the medication.

GLP-1 agonists are indicated for type 2 diabetes treatment. They also have shown benefits for obesity and weight management treatment. However, weight loss is excluded from coverage on Humana commercial and MAPD/PDP plans, so GLP-1 agonists will not be covered for this use.

GLP-1 agonists currently approved by the U.S. Food and Drug Administration (FDA) for type 2 diabetes mellitus treatment as an adjunct to diet and exercise include:

  • Adlyxin® (lixisenatide)
  • Bydureon® (exenatide)
  • Byetta® (exenatide)
  • Mounjaro® (tirzepatide)
  • Ozempic® (semaglutide)
  • Rybelsus® (semaglutide)
  • Trulicity® (dulaglutide)
  • Victoza® (liraglutide)

GLP-1 agonists currently approved by the FDA for obesity and chronic weight management treatment as an adjunct to a reduced-calorie diet and increased physical activity include:

  • Saxenda® (liraglutide)
  • Wegovy® (semaglutide)
