"On behalf of the Endocrine Society, thank you for the opportunity to submit these comments on the Calendar Year (CY) 2025 Medicare Physician Fee Schedule (MPFS) proposed rule. Founded in 1916, the Endocrine Society represents approximately 18,000 physicians and scientists engaged in the treatment and research of endocrine disorders, such as diabetes, hypertension, obesity, osteoporosis, endocrine cancers (i.e., thyroid, adrenal, ovarian, pituitary) and thyroid disease. Many of the patients our members treat are Medicare beneficiaries. We also note that there is a shortage of endocrinologists; wait lists to see an endocrinologist can be many months long; diagnosis and treatment can be extremely complex; the amount of work outside of clinic time is increasing; and endocrinologists have some of the lowest salaries of medical subspecialists, yet they have not seen significant increases in Medicare payments in decades. Consequently, the payment policies and other revisions in the MPFS are of great importance to our members."
