Summary & Overview
CPT 51725: Cystometrogram — Bladder Pressure and Capacity Test
CPT code 51725 represents a cystometrogram, an urodynamic procedure that measures bladder capacity and intravesical pressure to evaluate bladder contraction and emptying. This test is central to diagnosing urinary incontinence, neurogenic bladder, and other lower urinary tract dysfunctions, making it an important procedure in urology and pelvic floor care nationwide. The code signals specialized diagnostic evaluation beyond basic office assessment and typically involves instrumentation and monitoring in outpatient facilities.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for CPT code 51725, typical sites of service, and the role of urodynamic testing in diagnostic pathways. The publication outlines common billing modifiers associated with the procedure and highlights the payer landscape relevant to reimbursement and coverage policy. It also summarizes related service lines and practical considerations for coding and billing workflows. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 51725 describes a cystometrogram, a procedure that measures bladder capacity and pressure to evaluate bladder contraction and expulsion function. It is used to diagnose urinary storage and voiding disorders by recording bladder behavior during filling and voiding.

Clinical & Coding Specifications
Clinical Context
A 62-year-old female with progressive urinary urgency, frequency, nocturia, and episodes of urge incontinence is referred to the urology clinic after conservative measures fail. The patient reports incomplete bladder emptying and intermittent dysuria. A focused history, physical exam, and bladder diary suggest lower urinary tract dysfunction. The clinician schedules a cystometrogram (51725) to quantify bladder capacity, compliance, detrusor overactivity, and voiding pressures.
The workflow: the patient presents to an outpatient urology procedure suite or an ambulatory surgery center. After informed consent and explanation of the study, a small transurethral catheter and a rectal or vaginal pressure-sensing device may be placed. Saline is instilled at a controlled rate while intravesical pressure is recorded to assess filling sensations, capacity, compliance, and involuntary contractions. The test may include leak point pressure measurements and provocation maneuvers. Results are reviewed by the urologist and used to guide management such as bladder retraining, medications, or targeted interventions.
