One of my providers saw a patient in the hospital at 11 AM for a UTI related to the patient's bladder cancer. At 3:50 in the afternoon of the same day, the patient's paperwork was signed admitting him to hospice services. Medicare is denying the service saying that the patient was in hospice on our date of service and the hospice provider is refusing to pay us because our services were provided prior to the "time" that the he was admitted to hospice care. It is my impression that hospice services are per day, not per hour, and that the hospice provider should be repsonsible for this charge. However, I am unable to find any documentation supporting this. Does any one have any advice?
