A complete blood count (CBC) measures red blood cells, white blood cells, hemoglobin, hematocrit, and platelets from a single blood draw. Doctors order it to check for anemia, infection, clotting problems, and many other conditions, and it is one of the most common lab tests in the United States. In 2026 a CBC costs between $8 and $200 without insurance, a spread of more than 20 times for the same test on the same analyzer.
Price differences come from billing, not lab quality. A hospital bills from its chargemaster, the internal list price that almost no insurer or informed cash patient pays in full. Independent labs and direct-to-consumer ordering sites publish flat cash prices, often $10 to $40 in 2026. Patients who are uninsured or choose not to use insurance can ask any provider for a written Good Faith Estimate before the draw, a right created by the No Surprises Act on January 1, 2022.
CoveredUSA built this guide from the 2026 Medicare Clinical Laboratory Fee Schedule at CMS.gov, consumer price data from FAIR Health Consumer, and Medicare coverage rules at Medicare.gov. Below: cash prices by site and CBC type, what Medicare pays, how to request a Good Faith Estimate, and the billing errors that inflate lab bills.
CBC Test Cost by Site of Service in 2026
The biggest cost driver of CBC Test is the site of service: where the procedure is performed. 2026 CMS price transparency data confirms a 2-3x billing differential between independent centers and hospital outpatient departments.
CBC Test prices without insurance vs. 2026 Medicare rates| Site of Service | Range Without Insurance | 2026 Medicare Rate |
|---|
| Direct-to-consumer lab (online order, walk-in draw) | $8 to $45 | $8 (CLFS 2026) |
| Independent or commercial reference lab | $15 to $75 | $8 (CLFS 2026) |
| Physician office or urgent care (lab sent out) | $25 to $120 | $8 (CLFS 2026) |
| Hospital outpatient laboratory | $60 to $200 | $8 (CLFS 2026) |
| Emergency department | $80 to $200 plus facility fee | $8 lab plus ED visit payment |
2026 ranges are typical cash prices and vary by region and by whether a manual differential is added. Medicare rate shown is the approximate 2026 Clinical Laboratory Fee Schedule payment for an automated CBC with differential; Medicare does not apply a deductible or coinsurance to it. Draw fees and physician visit charges are billed separately.

Why the Same Procedure Is So Much More at a Hospital
The 2026 CBC cost gap between a direct-to-consumer lab and a hospital comes from billing structure. Hospitals bill from a chargemaster that is set to cover overhead across all departments, then negotiate commercial rates off that list. Independent labs run high-volume automated analyzers with low overhead and publish flat prices. The blood sample is analyzed on near-identical equipment either way, and results are reported in the same format.
Cash patients are the group most exposed to the chargemaster. Most hospitals publish a self-pay discount policy of 20 to 60 percent off list price, and federal hospital price transparency rules require posted prices. Asking for the cash price before the draw, and requesting a Good Faith Estimate in writing, often cuts a hospital CBC bill by half or more. When the test is not urgent, ordering through an independent lab is typically the lowest-cost route.
CBC test cost by type in 2026
CBC orders come in a few forms, and the form changes the 2026 price. A basic CBC reports cell counts only. A CBC with automated differential also breaks white cells into types and is the most common order. A manual differential adds a technologist's slide review when the analyzer flags abnormal cells.
Typical cost by variant| CBC type | What it reports | Cash price range (2026) |
|---|
| CBC without differential | Red cells, white cells total, hemoglobin, hematocrit, platelets | $8 to $35 |
| CBC with automated differential | All of the above plus white cell types | $10 to $60 |
| CBC with manual differential | Technologist slide review of flagged cells | $20 to $90 |
| CBC bundled in a panel | CBC plus metabolic panel or lipid panel | $30 to $120 |
2026 prices are typical direct-to-consumer and independent lab ranges. Hospital chargemaster prices for the same test can run higher, up to $200 in 2026.

What Medicare Pays for CBC Test
Original Medicare covers a CBC under Medicare Part B when a doctor orders it for a medical reason. Lab tests are paid under the Clinical Laboratory Fee Schedule, which sets the 2026 payment for an automated CBC with differential at about $8. Medicare Part B charges $0 for covered clinical lab tests: no 2026 Part B deductible ($283) and no 20% coinsurance apply. Medicare Advantage plans must cover the same tests but may require an in-network lab, and Medigap is not needed for this cost because there is no coinsurance to fill.
Commercial insurance works differently from Medicare. A CBC ordered for symptoms is not a USPSTF preventive service, so on an ACA-compliant plan the lab bills against your deductible in 2026 unless your plan covers labs at a flat copay. Members of high-deductible plans often pay the insurer's negotiated rate, commonly $10 to $50, until the deductible is met. Out-of-network labs can cost far more, and prior authorization is rarely required for a routine CBC. When the cash price is lower than your negotiated rate, paying cash is allowed, though the payment may not count toward your deductible.
The No Surprises Act, effective January 1, 2022, gives uninsured and self-pay patients the right to a written Good Faith Estimate from any provider or facility before a scheduled service. For a CBC scheduled at least 10 business days out, the provider must deliver the Good Faith Estimate at least 3 business days before service. For a CBC scheduled 3 to 9 business days out, the estimate is due at least 1 business day before service. Services scheduled less than 3 business days out do not require an advance estimate, but you can still ask for one. Full guidance is at cms.gov/nosurprisesact. Original Medicare and Medicaid enrollees have separate protections.
To request a Good Faith Estimate for a CBC in 2026, follow these steps: (1) Call the lab, hospital, or physician office and say you are self-pay or uninsured. (2) Ask for a written Good Faith Estimate listing the test code (CPT 85025 or 85027), the lab fee, the blood draw fee, and any physician or facility charge. (3) Give your ZIP code and any planned add-ons such as a metabolic panel or manual differential. (4) Confirm the timing: 3 business days before service if scheduled 10 or more business days out, 1 business day if scheduled 3 to 9 business days out. (5) Keep the written estimate; if the final bill exceeds it by $400 or more, you can file a patient-provider dispute within 120 days of the bill date.
A Good Faith Estimate for a CBC is not a guaranteed final bill. Common reasons actual charges exceed it include add-on tests the doctor orders after the draw, a manual differential triggered by abnormal cells, a separate blood draw or specimen handling fee, a hospital facility fee, and a pathologist review. If the final bill exceeds the Good Faith Estimate by $400 or more, the 2026 federal patient-provider dispute process at cms.gov/nosurprisesact accepts claims for 120 days after the bill date. Patients can also use the CoveredUSA medical bill analyzer to check line items.
What Factors Affect Cost
- Site of service: direct-to-consumer and independent labs charge $8 to $45 in 2026, while hospital outpatient labs bill $60 to $200 from the chargemaster for the same CBC.
- CBC type and add-ons: a manual differential, or a CBC bundled with a metabolic or lipid panel, raises the 2026 price by $10 to $60.
- Insurance status: uninsured cash price, in-network commercial rate (often $10 to $50 in 2026 until the deductible is met), and Original Medicare ($0 for covered lab tests) differ widely. Out-of-network labs can bill far above negotiated rates, and the No Surprises Act protects against some surprise lab bills.
- Self-pay programs at independent labs: direct-to-consumer ordering sites and national reference labs sell CBC tests at flat cash prices, typically 30 to 60 percent or more below hospital chargemaster cash prices, with no doctor visit needed in many states.
- Hospital chargemaster discount ask: most hospitals publish a self-pay discount of 20 to 60 percent off chargemaster; some apply it automatically for uninsured patients and some require you to ask, so request the cash price and a Good Faith Estimate before the draw.
- Sliding-scale FQHCs: Federally Qualified Health Centers charge by household size and income, and labs such as a CBC can cost $0 to a small fee for patients below 100 percent of the federal poverty level. See the CoveredUSA [federal poverty level](/federal-poverty-level) page for 2026 thresholds.
- Preventive status: a CBC is not a USPSTF preventive service on its own, so ACA-compliant plan cost-sharing follows your 2026 deductible, copay, or coinsurance. Original Medicare charges $0 for the test when a doctor orders it for a medical reason.
Common CBC Test Billing Errors
CBC bills are small, which makes errors easy to miss. Check for these before paying a 2026 lab bill:
- CBC billed with a manual differential when the analyzer produced an automated differential, adding $10 to $60 in 2026 for work not performed.
- Duplicate CBC codes (85025 and 85027 together) on the same draw date. Only one CBC should be billed per specimen.
- Medicare beneficiary charged coinsurance or the $283 Part B deductible for a covered clinical lab test, which should be $0.
- Out-of-network lab used by an in-network doctor's office without telling the patient, producing a surprise balance bill (the No Surprises Act may apply).
- Separate venipuncture or specimen handling fee added by a hospital on top of a bundled cash price.
- Hospital facility fee billed for a lab drawn at a hospital-owned clinic that is priced like an office.
Frequently Asked Questions
How much does a CBC test cost without insurance in 2026?
A CBC test costs $8 to $200 without insurance in 2026, with a national median near $30. Direct-to-consumer and independent labs typically charge $8 to $45, physician offices and urgent care $25 to $120, and hospital outpatient labs $60 to $200 from the chargemaster. A manual differential or a bundled panel can add $10 to $60. Prices vary by region, so check FAIR Health Consumer at fairhealthconsumer.org for your ZIP code and ask for the cash price before the blood draw.
What does Medicare pay for a CBC test in 2026?
Original Medicare pays about $8 for an automated CBC with differential under the 2026 Clinical Laboratory Fee Schedule at cms.gov. Medicare Part B covers medically necessary lab tests at 100 percent, so beneficiaries pay no 2026 deductible ($283) and no 20 percent coinsurance for the test itself. Medicare Advantage plans must cover the same test but may require an in-network lab. Medigap is not needed for CBC cost because there is no coinsurance. Office visit and draw-related charges can still carry normal cost-sharing.
How do I request a Good Faith Estimate for a CBC test?
Call the lab, hospital, or physician office and say you are self-pay or uninsured. Ask for a written Good Faith Estimate listing the test code (85025 or 85027), lab fee, draw fee, and facility charges. Give your ZIP code and planned add-ons. For a CBC scheduled 10 or more business days out, the estimate is due 3 business days before service; for 3 to 9 business days out, 1 business day before. Keep the document, and start at cms.gov/nosurprisesact if you need to dispute a bill that exceeds it by $400 or more.
What is the No Surprises Act and does it apply to me?
The No Surprises Act is a federal law effective January 1, 2022 that protects patients from surprise medical bills and requires providers to give uninsured and self-pay patients a written Good Faith Estimate before scheduled services. It applies to hospitals, independent labs, physician offices, and outpatient facilities. It does not cover Original Medicare or Medicaid enrollees, who have separate protections. If your final CBC bill exceeds the estimate by $400 or more, you can file a patient-provider dispute within 120 days at cms.gov/nosurprisesact.
How do I get a written cash-pay quote for a CBC test?
Call the lab before scheduling and ask, What is your self-pay cash price for a CBC with differential? Request the answer in writing or as a Good Faith Estimate. Ask whether the price includes the blood draw, the physician interpretation, and any facility fee, and whether a same-day payment discount applies. Direct-to-consumer labs usually list flat 2026 prices online, often $10 to $40. Hospitals must post prices under federal transparency rules, but their chargemaster rate is typically the highest option, so compare at least two sites.
Can I negotiate a CBC test bill after the fact?
Yes. Even after a bill arrives, patients can negotiate a CBC charge. Ask for an itemized bill, check the test code and modifiers, then ask for the self-pay discount, which many hospitals set at 20 to 60 percent off chargemaster. Offering to pay promptly often earns a 30 to 50 percent reduction. If you had a Good Faith Estimate and the final bill exceeds it by $400 or more, you can file a patient-provider dispute within 120 days of the bill date through cms.gov/nosurprisesact.
What is the difference between hospital and independent lab CBC cost?
In 2026 a hospital outpatient lab bills $60 to $200 for a CBC from its chargemaster, while an independent or direct-to-consumer lab charges $8 to $45. Original Medicare pays about $8 at either site because the Clinical Laboratory Fee Schedule is site-neutral for the test itself. The gap comes from hospital overhead and list pricing, not from a different test. Hospitals may also add a facility or draw fee. Ask for the cash price and a Good Faith Estimate from both before choosing.
Will my insurance cover a CBC test?
Usually yes when a doctor orders it for a medical reason, but a CBC is not a USPSTF preventive service on its own, so ACA-compliant plans apply your deductible, copay, or coinsurance in 2026. High-deductible plan members often pay the negotiated rate, commonly $10 to $50, until the deductible is met. Original Medicare charges $0 for covered lab tests. Check that the lab is in your network, because out-of-network labs can bill much more. Prior authorization is rarely required for a routine CBC.
What is the difference between a CBC and a comprehensive metabolic panel?
A CBC counts blood cells (red cells, white cells, platelets) and measures hemoglobin to screen for anemia, infection, and clotting problems. A comprehensive metabolic panel (CMP) measures blood chemistry: glucose, electrolytes, kidney function, and liver enzymes. They answer different questions and are often ordered together. In 2026 a CBC typically costs $8 to $45 at an independent lab and a CMP $10 to $50. Medicare pays about $8 for a CBC and about $11 for a CMP, with no deductible or coinsurance for covered lab tests.
