Medicare Hospital Discharge 99238 and Nursing Facility Admit on the Same Day

Medicare guidelines allow for a hospital discharge and Nursing Facility admit on the same day according to their Processing Manual. However, Medicare continually denies payment for one of the visits stating it was partially paid on a previous claim for the same date of service. Is anyone else having issues with this? I don't see that there needs to be a modifier etc attached. Thanks for your feedback.
