51792 Urinary reflex study Medicare reimbursement rates in Missouri

A urinary reflex study evaluates the reflex response involved in urinary control, rather than simply measuring urine flow or bladder filling pressure. The clinician stimulates a relevant reflex pathway and records the physiologic response to assess neuromuscular function. Urologists and other clinicians evaluating urinary dysfunction may order the test when neurologic involvement is suspected; it is commonly performed in an office urodynamics setting by trained staff, with physician interpretation.

Select this service when the documented test is a urinary reflex study, not a cystometrogram, uroflow measurement, or sphincter electromyography study. The record should identify the reflex testing performed, the clinical indication, and the findings supporting the interpretation. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. The service may be billed globally or split into professional interpretation with modifier 26 and technical equipment and staff with modifier TC. When multiple procedures occur in one session, the highest-valued is paid in full and other procedures are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate; assistant-at-surgery payment requires documented medical necessity, and co-surgeons and team surgery are not permitted.
