  • Projections assume that 2019 Endocrine Society guidelines recommendations are fully implemented (i.e., all older adults with prediabetic HbA1c or FPG are screened with an OGTT). The costs of low-, medium-, and high-cost visits are based on Current Procedural Terminology codes 99212, 99213, and 99214, respectively, and come from the 2019 Medicare physician fee schedule. Costs for an OGTT come from the 2019 Medicare clinical laboratory fee schedule.
