The patient is unable to travel due to severe osteoarthritis and limited mobility; diagnoses may include chronic heart failure, diabetes mellitus with peripheral neuropathy, or end-stage chronic obstructive pulmonary disease. The workflow begins with a physician order, insurance verification, and scheduling. The phlebotomist documents the visit, specimen collection, chain-of-custody if required, and returns the specimen to the laboratory. The billed item P9604 represents a prorated one-way travel allowance associated with performing the specimen collection for a homebound or nursing home–bound patient; it is billed in conjunction with the laboratory collection service and appropriate specimen handling codes.
