Urine Culture with Colony Count
CPT 87086 is a urine culture ordered when a urinary tract infection (UTI) is suspected. It grows bacteria from your urine sample over 24 to 48 hours to identify the specific organism causing infection. Medicare pays approximately $8 to $10 for this test, but providers charge an average of $49.83. Understanding the difference between a urine culture and a basic urinalysis can save you money and unnecessary testing.

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. A urine culture costs Medicare the same amount regardless of where the lab is located.
| Metric | Value |
|---|---|
| Medicare CLFS Rate | ~$8 to $10 |
| Average Provider Charge | $49.83 |
| Markup Ratio | ~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 Urine Culture Test For?
A urine culture (CPT 87086) takes a urine sample and places it in a growth medium for 24 to 48 hours. If bacteria are present, they multiply into visible colonies. The lab then counts the colonies and identifies the species, most commonly E. coli, Klebsiella, or Proteus.
What the Culture Reveals
- Whether bacteria are present in the urine
- Colony count (how many bacteria per mL)
- Species identification (which bacteria)
- Often paired with sensitivity testing (which antibiotics will work)
When a Culture Is Most Valuable
- Recurrent UTIs (3+ per year)
- Complicated UTIs (male patients, pregnancy, diabetes)
- Failed initial antibiotic treatment
- Catheter-associated infections
- Atypical symptoms or unclear diagnosis
For a straightforward, uncomplicated UTI with classic symptoms (burning, urgency, frequency) in an otherwise healthy woman, many clinical guidelines support empiric antibiotic treatment based on urinalysis results alone. The culture adds cost and a 24 to 48 hour delay without changing treatment in most uncomplicated cases. If you are prescribed antibiotics immediately, the culture result usually arrives after treatment has already begun.
Where to Get a Urine Culture for Less
If you need a urine culture, where you get it tested matters significantly for cost. Here are your options from cheapest to most expensive:
Direct-to-Consumer Labs: $20 to $40
Services like Walk-In Lab and Ulta Lab Tests offer urine culture testing at a fraction of hospital pricing. You can order the test online and visit a local lab collection site. Results are typically available in 2 to 3 business days.
Independent Labs (with doctor's order): $15 to $30
If your doctor orders a urine culture, ask for the order to be sent to an independent lab (Quest or LabCorp) rather than the hospital's in-house lab. Independent labs charge significantly less for the same test.
Hospital Outpatient Labs: $40 to $80+
Hospital labs are the most expensive option. If you visit an ER or urgent care for a UTI, the urine culture is typically processed in-house and billed at the facility's rate. For non-urgent situations, ask if you can take the lab order to an independent lab instead.
What Insured Patients Actually Pay for a Urine Culture
Insurance companies negotiate lab rates that are typically close to or slightly above the Medicare CLFS rate. What you owe depends on your plan type:
| Your Situation | What You Likely Pay | How It Works |
|---|---|---|
| Copay plan (deductible met or N/A) | $0 to $10 | Many plans cover lab work at 100% after deductible |
| Coinsurance plan (deductible met) | $2 to $5 | 20% of negotiated rate ($8 to $25) |
| High-deductible plan (deductible NOT met) | $8 to $40 | Full negotiated rate applied to your deductible |
| Medicare Part B | $0 | Medicare covers clinical lab tests at 100% (no coinsurance) |
Common Billing Problems with CPT 87086
Double charge: urinalysis plus culture when only one was needed
It is standard practice to order both a urinalysis (81001, ~$5 to $10) and a culture (87086, ~$50) together. However, for a straightforward UTI with classic symptoms, the urinalysis alone may have been sufficient for diagnosis. If you see both charges and your symptoms were uncomplicated, ask whether the culture changed your treatment plan. If your doctor prescribed antibiotics before the culture results came back, the culture likely did not change your care.
Sensitivity testing added automatically
When a culture comes back positive, the lab often automatically runs antibiotic sensitivity testing (CPT 87181 or 87184), which generates an additional charge. While sensitivity testing is valuable for guiding antibiotic choice, it is sometimes run reflexively even when the patient is already responding to empiric treatment. Check your bill for sensitivity charges, especially if your initial antibiotics resolved the infection.
ER facility fee on top of lab charges
If you went to the ER for UTI symptoms, the urine culture charge is just one part of a much larger bill that includes facility fees, physician fees, and possibly other tests. The culture itself may be $50, but the total ER visit can be $500 to $2,000+. For uncomplicated UTI symptoms, urgent care or a telehealth visit is significantly cheaper and can prescribe the same antibiotics.

Frequently Asked Questions
How much does a urine culture (CPT 87086) cost without insurance?
Without insurance, a urine culture costs $30 to $80 at hospitals and clinics, with the national average at $49.83. Direct-to-consumer labs offer urine cultures for $20 to $40. Medicare pays approximately $8 to $10 for this test under the Clinical Laboratory Fee Schedule.
What is the difference between a urine culture and a urinalysis?
A urinalysis (CPT 81001) is a quick screening test that checks for signs of infection like white blood cells, nitrites, and bacteria. It costs $5 to $10 and gives results in minutes. A urine culture (CPT 87086) grows bacteria from the sample over 24 to 48 hours to identify the exact species causing infection. The culture is more expensive and slower, but provides definitive bacterial identification.
Do I always need a urine culture if I have UTI symptoms?
Not always. For uncomplicated UTIs with classic symptoms (burning, frequency, urgency) in otherwise healthy women, many clinical guidelines support empiric antibiotic treatment based on symptoms and urinalysis results alone. A culture is more important for recurrent UTIs, complicated infections, pregnant patients, men, or when initial treatment fails. Ask your doctor whether a culture will change your treatment plan.
Why was I charged for both a urinalysis and a urine culture?
A urinalysis (81001) and urine culture (87086) are two different tests that generate separate charges. The urinalysis screens for infection, and if positive, the culture identifies the specific bacteria. While ordering both is common, for straightforward UTIs the culture may not have been clinically necessary. If your doctor prescribed antibiotics before the culture results returned, the culture likely did not change your treatment.
