PSA Test (Prostate Specific Antigen)
CPT 84153 is a PSA blood test used to screen for prostate cancer. Medicare pays $17.98 for this test under the Clinical Laboratory Fee Schedule, but providers charge an average of $99.45 (a 5.5x markup). The same test, same blood draw, can cost you nothing or $99 depending on the diagnosis code your provider uses. Direct-to-consumer labs offer PSA tests for $30 to $60.

How Lab Pricing Works (Clinical Laboratory Fee Schedule)
Unlike physician services that use RVUs and geographic adjustments, lab tests are priced under the Medicare Clinical Laboratory Fee Schedule (CLFS). The CLFS sets a single national rate for each lab test. There are no RVU components and no geographic cost adjustments. The same PSA test costs Medicare $17.98 whether drawn in New York City or rural Alabama.
| Metric | Value |
|---|---|
| Medicare CLFS Rate | $17.98 |
| Average Provider Charge | $99.45 |
| Markup Ratio | 5.5x |
| Pricing Method | National rate (CLFS), no geographic variation |
Lab tests are priced under the Clinical Laboratory Fee Schedule, not the Physician Fee Schedule. Medicare lab rates are set nationally and do not vary by geographic location.
What Does a PSA Test Measure?
Prostate Specific Antigen (PSA) is a protein produced by the prostate gland. A blood test measures the level of PSA in your blood. Elevated PSA levels can indicate prostate cancer, but they can also be caused by benign conditions like an enlarged prostate (BPH) or prostatitis.
PSA screening is controversial. The USPSTF recommends shared decision-making between men ages 55 to 69 and their doctors about whether to get screened. For men under 55 or over 69, routine screening is generally not recommended unless there are specific risk factors. Medicare covers annual PSA screening for men 50 and older.
If your PSA is elevated, your doctor may order a free PSA test (CPT 84154) to help distinguish between prostate cancer and benign conditions. The ratio of free to total PSA provides additional diagnostic information.
Screening vs. Diagnostic: Same Test, Different Cost
This is the single most important thing to understand about PSA billing. The same blood test, same blood draw, same lab analysis can cost you nothing or $99 depending on the diagnosis code your provider attaches to the order.
| Coding | ICD-10 Code | What It Means | Your Cost |
|---|---|---|---|
| Screening | Z12.5 | Encounter for screening for prostate cancer | $0 (preventive) |
| Diagnostic | R97.20 | Elevated prostate specific antigen | Subject to cost-sharing |
Where to Get a PSA Test for Less
You do not have to use your hospital's lab. Lab pricing varies dramatically depending on where you go. Here are your options, ranked from cheapest to most expensive:
Direct-to-Consumer Labs: $30 to $60
Services like Quest Diagnostics (walk-in), LabCorp patient service centers, Ulta Lab Tests, and Jason Health allow you to order a PSA test without a doctor's order in most states. You pay upfront, get your blood drawn at a local lab, and receive results online. Prices range from $30 to $60 for a PSA test.
Independent Labs (with doctor's order): $20 to $50
If your doctor sends you for lab work, ask for the order to be sent to an independent lab (Quest or LabCorp) rather than the hospital's in-house lab. Independent labs typically charge 50% to 80% less than hospital outpatient labs for the same test.
Hospital Outpatient Labs: $80 to $150+
Hospital labs are the most expensive option. They often add facility fees on top of the test cost. A PSA at a hospital lab can cost $80 to $150 or more. If your doctor is part of a hospital system, the lab order may automatically route to the hospital lab. Ask if you can use an independent lab instead.
What Insured Patients Actually Pay for a PSA Test
What you owe depends on your insurance plan and, critically, whether the test is coded as screening or diagnostic:
| Your Situation | What You Likely Pay | How It Works |
|---|---|---|
| Medicare Part B (screening, men 50+) | $0 | Annual screening PSA covered at 100%, no coinsurance |
| ACA plan (screening, coded Z12.5) | $0 | Preventive screening covered with no cost-sharing |
| Diagnostic (deductible met) | $0 to $10 | Many plans cover lab work at 100% after deductible |
| HDHP (diagnostic, deductible NOT met) | $10 to $50 | Full negotiated rate applied to your deductible |
| Uninsured (hospital lab) | $50 to $150 | Full provider charge, ask for cash-pay rate |

Frequently Asked Questions
How much does a PSA test cost without insurance?
Without insurance, a PSA test (CPT 84153) costs $50 to $150 at most hospitals and clinics, with the national average charge at $99.45. Direct-to-consumer labs offer PSA tests for $30 to $60 without a doctor's order. Medicare pays $17.98 for this test.
Is a PSA test free under preventive care?
It depends on how it is coded. If your PSA is ordered as screening (ICD-10 Z12.5), it may be covered at no cost under ACA preventive care rules. If coded as diagnostic (e.g., R97.20 for elevated PSA), cost-sharing applies. Medicare covers annual PSA screening for men 50 and older at no cost. The same blood draw can cost you nothing or $99 depending on the diagnosis code your provider uses.
How often should men get a PSA test?
The USPSTF recommends shared decision-making between men ages 55 to 69 and their doctors about PSA screening. Medicare covers annual PSA screening for men 50 and older. For men under 55 or over 69, routine screening is generally not recommended unless there are specific risk factors. Discuss with your doctor.
What is the difference between CPT 84153 and CPT 84154?
CPT 84153 is the total PSA test, which is the standard screening test. CPT 84154 is the free PSA test, which measures the unbound portion of PSA. Free PSA is typically ordered when total PSA is elevated (between 4 and 10 ng/mL) to help distinguish between prostate cancer and benign conditions like BPH (benign prostatic hyperplasia).
