Vitamin B-12 Level
CPT 82607 measures Vitamin B-12 (cyanocobalamin) levels in your blood. It is one of the most frequently added tests during routine blood work, ordered for over 3.3 million Medicare beneficiaries in 2023. The $85.76 average provider charge for a single vitamin level is steep, especially since direct-to-consumer labs offer the same test for $15 to $30. B-12 is often ordered as a "just in case" add-on. Each extra test your doctor orders generates its own code, its own charge, and its own line on your bill.

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. Medicare pays the same rate for a B-12 test regardless of where the lab is located. The CLFS rate for CPT 82607 is approximately $11 to $15.
| Metric | Value |
|---|---|
| Medicare CLFS Rate | ~$11 to $15 |
| Average Provider Charge | $85.76 |
| Markup Ratio | 6x to 8x |
| 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 Vitamin B-12 Test Measure?
CPT 82607 measures the level of Vitamin B-12 (cyanocobalamin) in your blood. B-12 is essential for nerve function, red blood cell formation, and DNA synthesis. Deficiency can cause anemia, neurological symptoms, and fatigue.
Result Ranges
- Below 200 pg/mL: Deficient
- 200 to 300 pg/mL: Borderline (may need further testing)
- 300 to 900 pg/mL: Normal
- Above 900 pg/mL: Elevated (usually from supplements)
Who Should Be Tested
- Vegetarians and vegans (B-12 comes primarily from animal products)
- Adults over 65 (absorption decreases with age)
- Patients on metformin or proton pump inhibitors
- Patients with symptoms: fatigue, numbness, tingling, memory issues
- Patients with malabsorption conditions (celiac, Crohn's, gastric bypass)
Where to Get a B-12 Test for Less
The price difference between labs is dramatic for B-12 testing. Here are your options, ranked from cheapest to most expensive:
Direct-to-Consumer Labs: $15 to $30
Services like Quest Diagnostics (walk-in), LabCorp, Ulta Lab Tests, Jason Health, and Walk-In Lab allow you to order a B-12 test without a doctor's order in most states. You pay upfront, get your blood drawn at a local lab, and receive results online. This is the cheapest option for paying out of pocket.
Independent Labs (with doctor's order): $20 to $40
If your doctor orders the test, ask for the order to be sent to an independent lab (Quest or LabCorp) rather than the hospital's in-house lab. The same B-12 assay at an independent lab costs a fraction of the hospital price.
Hospital Outpatient Labs: $60 to $150+
Hospital labs are the most expensive option. The $85.76 national average charge reflects typical hospital pricing, and some charge well over $100. 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 B-12 Test
Most insurers cover B-12 testing when medically indicated. What you owe depends on your plan design:
| 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) | $1 to $5 | 20% of negotiated rate ($5 to $25) |
| High-deductible plan (deductible NOT met) | $8 to $30 | 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 82607
Ordered as a routine add-on without clinical indication
B-12 is frequently ordered alongside other routine blood work without a specific clinical reason. Some doctors add it as a "just in case" test, especially for older patients or vegetarians. While it is a legitimate test for those with risk factors, ordering it annually for every patient regardless of symptoms adds $86 per test. If you see B-12 on your lab order, ask your doctor whether there is a specific clinical reason for testing and whether it is necessary this year.
Stacking multiple vitamin and nutrient tests
It is common to see B-12 (82607) ordered alongside Vitamin D (82306), folate (82746), and iron studies (83540) in the same blood draw. Each generates a separate charge. A B-12 at $86, Vitamin D at $177, and folate at $60 adds $323 to your bill before you even count the metabolic panel and CBC. Review your lab order before the blood draw and ask which tests are truly necessary for your situation.
Hospital lab vs independent lab pricing
If your doctor is part of a hospital system, your lab order may automatically route to the hospital's outpatient lab. Hospital labs charge significantly more than independent labs for the same B-12 test. You can usually ask for the lab order to be sent to Quest or LabCorp instead, which can cut the cost by 50% to 75%.

Frequently Asked Questions
How much does a Vitamin B-12 test cost without insurance?
Without insurance, a B-12 test (CPT 82607) costs $40 to $150 at most hospitals and clinics, with the national average charge at $85.76. Direct-to-consumer labs like Quest, LabCorp, Ulta Lab Tests, and Jason Health offer the same test for $15 to $30 without a doctor's order in most states. Medicare pays approximately $11 to $15.
Is a Vitamin B-12 test necessary at my annual physical?
Not always. B-12 testing is appropriate for patients with risk factors: vegetarians and vegans, adults over 65, patients taking metformin or proton pump inhibitors long-term, and those with symptoms of deficiency (fatigue, numbness, tingling, memory problems). Routine annual screening for healthy, asymptomatic patients without risk factors is generally not recommended and adds $86 to your bill each time.
Why does each additional blood test generate a separate charge?
Every lab test has its own CPT code and its own price, even when drawn from the same blood sample at the same time. When your doctor says "we will add a few more tests," each add-on generates a separate line item on your bill. A B-12 adds $86, a Vitamin D adds $177, and a thyroid test adds $83 at average provider charges. Before your blood draw, ask to see the complete list of tests being ordered and discuss whether each one is clinically warranted.
Does Medicare cover the Vitamin B-12 test at 100%?
Yes. Medicare Part B covers clinical laboratory tests, including the B-12 level (CPT 82607), at 100% of the Clinical Laboratory Fee Schedule rate. There is no coinsurance or copay for lab tests under Medicare. You pay $0 out of pocket, as long as the test is medically necessary and ordered by your treating physician.
