Assessing the Impact of the Center for Medicare and Medicaid Services Policy Guidance on Part D Prescriptions Among Hospice Patients.

Hospice care facilities are required to provide prescription drugs related to a hospice patient's terminal illness. From October 2010 to present, the Center for Medicare and Medicaid Services (CMS) has issued a series of communications regarding Medicare paying for hospice patients' prescription drugs under Part D that should be covered under the hospice Medicare Part A benefit. On April 4, 2011, CMS issued specific policy guidance to providers aimed at preventing inappropriate billing. While CMS has documented Part D prescription decreases in hospice patients, no research exists that connects these decreases and the policy guidance. This study aims to evaluate the effect of the April 4, 2011, policy guidance on hospice patients' Part D prescriptions. This study employed generalized estimating equations to assess (1) total monthly average prescriptions of all medications and (2) four categories of commonly prescribed hospice medications in pre-and-post policy guidance. This research used the Medicare claims of 113,260 Part D-enrolled Medicare male patients aged 66 and older between April 2009 and March 2013, including 110,547 non-hospice patients and 2713 hospice patients. Hospice patients' monthly average total Part D prescriptions decreased from 7.3 pre-policy guidance to 6.5 medications following the issuing of the guidance, while the four categories of hospice-specific medications decreased from .57 to .49. The findings of this study show that CMS's guidance issued to providers to prevent the inappropriate billing of hospice patients' prescriptions to the Part D benefit may lead to Part D prescription decreases as observed in this sample.
