Most cost guides on this site price one thing. This one has to price a stack, because that is what urodynamics actually is: a set of separate bladder measurements done in a single appointment, each with its own CPT code and its own price.
That single fact is the most useful thing a cash payer can know about this test. Two people can walk into the same clinic on the same day for what a scheduler calls “urodynamics” and leave with bills that differ by ten times, because one of them got four codes on the claim and the other got one. The tables below show what each component adds at 2026 Medicare rates and what the cash market charges for the whole thing. All figures were verified on September 3, 2026.
What Does Urodynamic Testing Cost Without Insurance?
Medicare office rates come from the CY 2026 Physician Fee Schedule (RVU26C, released June 30, 2026), calculated using the standard 2026 conversion factor of $33.4009. Hospital outpatient rates come from the July 2026 Outpatient Prospective Payment System Addendum B. Cash prices come from MDsave and HEALTHdrum listings read September 3, 2026, and marketplace prices move between reads.
| Component (CPT code) | Office rate | Hospital outpatient rate | What it adds |
|---|---|---|---|
| Complex uroflowmetry (51741) | $15.36 | $220.60 | Measures flow rate during one void |
| Post-void residual by ultrasound (51798) | $12.69 | $60.27 | Bladder scan after voiding |
| Temporary bladder catheter (51702) | $65.47 | $135.93 | Needed to fill and measure |
| Sphincter EMG, non-needle (51784) | $66.47 | $131.46 | Muscle activity during voiding |
| Complex cystometrogram (51726) | $270.88 | $255.26 | Bladder pressure during filling |
| Cystometrogram plus urethral pressure profile (51727) | $331.00 | $712.40 | Adds urethral pressure |
| Cystometrogram plus voiding pressure (51728) | $336.68 | $712.40 | Adds pressure-flow study |
| Cystometrogram plus voiding pressure and urethral profile (51729) | $354.05 | $712.40 | The most complete single code |
| Intra-abdominal voiding pressure add-on (51797) | $154.98 | Packaged, $0 separate | Abdominal pressure via rectal catheter |
| Needle sphincter EMG (51785) | $392.46 | $255.26 | Needle electrode version |
| Whole study | Low | Average | High |
|---|---|---|---|
| Simple uroflow with bladder scan, office (51741 + 51798) | $28.05 | $28.05 | $28.05 |
| Complete study, office, Medicare benchmark (51729 + 51797 + 51741 + 51784 + 51702) | $656.33 | $656.33 | $656.33 |
| Cystometrogram, cash marketplace (MDsave) | $409 | $601 | $783 |
| Urinary muscle study, cash marketplace (MDsave) | $152 | $459 | $778 |
| Urodynamics, published provider cash prices (one Florida metro) | $600 | $750 | $1,400 |
Sources disagree about the top of the range, and the disagreement is real rather than a rounding issue. MDsave puts the estimated national average for a cystometrogram at $1,194 against its own $601 marketplace average. The provider-published cash prices in the HEALTHdrum listing for the Coral Springs, Florida area cluster at $600 and $750 for urology practices but jump to $1,400 for OB/GYN practices doing the same testing. The honest cross-source range for a complete study is $400 to $1,400.
The stack is the story
Look at the office column again. A complex cystometrogram with voiding pressure and a urethral pressure profile (51729) pays $354.05 on its own. Add the intra-abdominal pressure catheter (51797) and you add $154.98, a 44% increase from one add-on code. Add sphincter EMG (51784) for $66.47, catheter insertion (51702) for $65.47, and uroflowmetry (51741) for $15.36, and the total reaches $656.33.
Now compare that to the floor. Complex uroflowmetry plus a post-void bladder scan is $28.05 at the same rates. That is the same clinic, the same equipment room, and the same staff. The 23-fold difference is entirely a function of how many codes go on the claim.
This is why “how much does urodynamic testing cost” has no single answer, and why the useful question to ask your clinic is not “what does it cost” but “which codes are you planning to bill.”
What Drives the Price
How many codes are on the claim. Covered above, and it is the dominant factor. A complete study is five codes. A screening-level workup can be one or two.
Office versus hospital outpatient. In a hospital outpatient department, the complex cystometrogram codes 51727, 51728 and 51729 all map to the same comprehensive ambulatory payment classification, which pays the hospital $712.40 for the whole encounter under 2026 rates. The physician then bills a separate professional fee, about $125.92 for 51729. So the hospital route runs roughly $838 in Medicare terms against $656 in an office, and the add-on codes get packaged rather than paid separately.
The simple tests are where the hospital markup is worst. Complex uroflowmetry pays $15.36 in an office and $220.60 in a hospital outpatient department. That is more than fourteen times the price for an identical measurement. If a clinic offers to do the simple flow study in the office rather than sending you to the hospital lab, take it.
Who is doing it. In the one metro area with published provider cash prices, urology practices charged $600 to $750 and OB/GYN practices charged $1,400 for urodynamics. Specialty matters to the price even when the test does not change.
Whether the study is needed at this stage at all. The AUA and the Society of Urodynamics, Female Pelvic Medicine and Urogenital Reconstruction publish a joint guideline on the surgical treatment of female stress urinary incontinence, published in 2017 and amended in 2023. Its Statement 5 says clinicians may omit urodynamic testing for the index patient seeking treatment when stress incontinence is clearly demonstrated, citing a 630-patient trial that found no difference in surgical outcomes between office evaluation alone and office evaluation plus urodynamics. Statement 6 says urodynamics may be performed in non-index patients, meaning those with prior surgery, voiding dysfunction, significant urgency, elevated post-void residuals, or an unconfirmed diagnosis. Asking which category you are in is a legitimate cost question, not a challenge to anyone’s judgment.
Cash Price vs. Insurance
Urodynamics sits in an awkward spot for insured patients: it is diagnostic, not preventive, so it lands against the deductible almost every time. That means a large share of insured patients pay something close to the full negotiated rate anyway, which narrows the gap between having coverage and not having it.
For a self-pay patient, the practical consequence is that a cash quote is often competitive with what an insured patient’s deductible would absorb. The MDsave marketplace average of $601 for a cystometrogram is below the estimated national average of $1,194 that the same page cites, and prepaid cash bundles usually cover facility and professional fees in one number instead of arriving as two or three separate bills.
The tradeoff is the standard one. Cash payments do not count toward a deductible or an out-of-pocket maximum, and if the urodynamic study is the first step toward surgery later in the same plan year, that credit can matter. If a bladder workup is likely to lead to a procedure, price the whole pathway before you decide, including our guides to cystoscopy cost and UroLift cost.

How to Pay Less
-
Ask which CPT codes will be billed, in advance. This is the single highest-leverage question on this page. A clinic that will tell you “51729, 51741, 51784, 51797 and 51702” has just handed you the ability to price the study exactly, and to ask whether every one of those is necessary.
-
Ask whether a uroflow answers the question first. A flow study with a bladder scan is $28.05 at 2026 Medicare office rates against $656.33 for a complete study. In some workups the simple test is the appropriate first step, and it is a fair question to raise.
-
Have it done in an office rather than a hospital outpatient department. Under 2026 Medicare rates the office is cheaper for every component in the stack, and dramatically cheaper for uroflowmetry ($15.36 versus $220.60) and the bladder scan ($12.69 versus $60.27).
-
Price a prepaid cash bundle. MDsave listed cystometrograms nationally from $409 to $783 with a $601 average on September 3, 2026, against an estimated national average of $1,194. Prepaid bundles also eliminate the split-bill problem where the facility and the physician invoice separately.
-
Compare a urology practice against an OB/GYN practice. The published cash prices in the one metro with provider-level data differed by roughly two times for the same testing depending on specialty. Both settings do this study competently, so it is worth calling both.
-
Look up the hospital’s posted cash rate yourself. Every hospital has to publish a machine-readable file with discounted cash prices. Our guide to hospital price transparency files explains how to find the entry for CPT 51728 or 51729 at a specific facility before you book.
-
Get itemized and negotiate if the bill has already arrived. A urodynamics bill with five line items is exactly the kind of claim where a code you did not need can be questioned. Request an itemized hospital bill, then work through our medical bill negotiation guide with the negotiation script. If the bill is from a nonprofit hospital, check charity care eligibility first, because that can wipe the balance rather than discount it.
Bottom Line
Budget $400 to $1,400 for a complete urodynamic study without insurance, and expect to land near $600 to $750 if you use a cash marketplace or a urology practice that publishes its price. Budget under $50 if what you actually need is a flow study and a bladder scan.
The difference between those two numbers is not quality of care and it is not geography. It is the number of CPT codes on the claim. Urodynamics is one of the few tests where a single question asked at scheduling (“which codes will you bill?”) can change the bill by several hundred dollars, and it works whether the patient is a man being evaluated for obstruction or a woman being worked up for stress incontinence. If a PSA or a prostate workup is what brought you here, our PSA test cost guide covers the lab side of the same evaluation.
