The workflow includes patient education and device selection during an outpatient visit, demonstration of insertion technique, provision of the single-use or reusable rectal catheter with or without balloon, and documentation of device model, laterality if applicable, and quantity. Training may occur in clinic or at bedside; home use is common after initial supervised sessions. The product is typically supplied by a durable medical equipment vendor or pharmacy, billed under HCPCS Level II code A4453. Typical sites of service are outpatient clinic, ambulatory surgery center for initial teaching if combined with other procedures, inpatient hospital for initiation in complex cases, or home health settings for ongoing therapy.
