CPT® Code 51725

A cystometrogram (CMG) is a diagnostic procedure utilized to assess the functional capacity of the bladder, specifically measuring bladder capacity and storage pressures. This evaluation is crucial for diagnosing various urological conditions, including urinary incontinence, difficulties with urination, and neurogenic bladder disorders. The procedure begins with the patient emptying their bladder, after which the volume of urine is recorded. Following this, the urethra is prepared by cleansing it with an antiseptic solution to minimize the risk of infection. A sterile catheter equipped with a sensor is then carefully inserted through the urethra into the bladder. Once in place, the bladder is filled with sterile saline, and the physician engages the patient in a dialogue to assess their sensations during the filling process, including feelings of fullness, pain, urgency, and any instances of leakage. The simple cystometrogram (CPT® Code 51725) specifically employs a spinal manometer or relies on visual observation of the fluid column entering the bladder to measure these parameters. During the procedure, the patient may be instructed to cough or strain, which helps the physician evaluate any potential stress incontinence by increasing abdominal pressure. It is important to note that while the simple CMG focuses on bladder capacity and storage pressures, it does not measure emptying pressures, which are not assessed in either simple or complex CMG procedures.
