Clinical & Coding Specifications
Clinical Context
A patient undergoing organ transplantation (for example, kidney, liver, heart, or lung transplant) and their designated caregiver require temporary lodging, meals, and transportation near the transplant center for the perioperative and immediate postoperative period. Typical workflow: the transplant coordinator verifies eligibility for transplant-related ancillary benefits and arranges per diem lodging and meal support beginning on the day of admission for the transplant procedure and continuing through the required post-transplant observation period. Transportation support is arranged for pre-transplant evaluations (laboratory and imaging visits), transport to the tertiary transplant center on the day of surgery, and outpatient follow-up visits during the early post-discharge period. Documentation in the patient chart includes the transplant indication, transplant date, dates of lodging/meals/transportation provided, names of recipient and caregiver if lodging covers both, and authorization reference from the payer when required. Billing uses S9975 reported as a per diem for combined lodging, meals, and transportation; charges are supported by itemized dates and a facility or vendor invoice where applicable.
