Clinical Context
A typical patient scenario involves an adult enrolled in a sponsored clinical trial receiving study-related meals while attending an on-site visit. The participant arrives for a multi-hour study visit that includes informed consent review, baseline assessments, specimen collection, and imaging. The participant’s primary caregiver accompanies them to assist with transportation and decision support. The clinical workflow: registration and verification of trial enrollment; confirmation of eligibility and required fasting or dietary restrictions; provision of meals per the trial protocol to the participant and one caregiver/companion; documentation in the research visit record including date/time, meal type, and that the meal was provided as part of the study; capture of the billing entry using HCPCS Level II code S9996 linked to the visit charge. Typical site of service is a clinical research facility, hospital outpatient research unit, or affiliated clinic where research visits are conducted. Service type: non-invasive ancillary support service (participant support — meal provision).
