Methodology
- Intra-abdominal voiding pressure (51797) is an add-on. It cannot stand alone. It only attaches to 51728 or 51729. It does not take a multiple-procedure reduction.
- Uroflowmetry (51741) is separate from the pressure-flow study. Billable only when run on separate equipment. It is not 'included' in the combined study.
- Combined studies (51728, 51729) already include the cystometrogram. Billing 51726 alongside them duplicates the CMG.
- If the patient did not void: do not code voiding pressure studies, uroflowmetry, the intra-abdominal add-on, or the companion voiding cystourethrogram. Ordered is not performed.
- Only one EMG variant per session. Surface (patch) and needle are not both billable.
- Medicare applies multiple-procedure reduction to most diagnostic tests billed on the same date, except the add-on 51797.
- Modifier 25 goes on the E/M, never on the procedure, when a significant and separately identifiable evaluation occurs on the same day.
