Comprehensive Metabolic Panel (CMP, 14 Blood Tests)
CPT 80053 is one of the most commonly ordered lab panels in the United States, measuring 14 blood chemicals in a single draw. Medicare pays $10.33 for this test under the Clinical Laboratory Fee Schedule, but providers charge an average of $59.85 (a 5.8x markup). Direct-to-consumer labs offer the same CMP for $10 to $30, making this one of the biggest markup categories in all of healthcare.

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 CMP costs Medicare $10.33 whether the lab is in Manhattan or rural Mississippi.
| Metric | Value |
|---|---|
| Medicare CLFS Rate | $10.33 |
| Average Provider Charge | $59.85 |
| Markup Ratio | 5.8x |
| 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 Comprehensive Metabolic Panel Measure?
A CMP measures 14 blood chemicals in a single draw, covering kidney function, liver function, electrolyte balance, and blood sugar:
Metabolic and Kidney
- Glucose (blood sugar)
- BUN (blood urea nitrogen)
- Creatinine (kidney function)
- Calcium
- Sodium
- Potassium
- CO2 (carbon dioxide/bicarbonate)
- Chloride
Liver and Protein
- Albumin
- Total protein
- ALP (alkaline phosphatase)
- ALT (alanine aminotransferase)
- AST (aspartate aminotransferase)
- Bilirubin (total)
The CMP is one of the most commonly ordered panels because it provides a broad snapshot of organ function. It is often ordered at annual physicals, pre-surgical evaluations, and for monitoring patients on medications that affect the liver or kidneys.
Where to Get a CMP 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: $10 to $30
Services like Quest Diagnostics (walk-in), LabCorp patient service centers, Ulta Lab Tests, Jason Health, and Walk-In Lab allow you to order a CMP 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 $10 to $30 for a CMP.
Independent Labs (with doctor's order): $15 to $40
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: $40 to $100+
Hospital labs are the most expensive option. They often add facility fees on top of the test cost. A CMP at a hospital lab can cost $60 to $100 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 CMP
Insurance companies negotiate lab rates that are typically 50% to 100% of the Medicare CLFS rate. Your insurer may pay even less than Medicare for labs. What you owe depends on your plan:
| 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 $6 | 20% of negotiated rate ($5 to $30) |
| High-deductible plan (deductible NOT met) | $5 to $35 | Full negotiated rate applied to your deductible |
| Medicare Part B | $0 | Medicare covers clinical lab tests at 100% (no coinsurance) |
| ACA preventive screening | $0 | If ordered as screening for at-risk patients |
Common Billing Problems with CPT 80053
Unbundling: Panel plus individual component tests
The most common billing error with a CMP is being charged for the panel (80053) plus individual component tests that are already included in the panel. For example, a separate glucose charge (82947) or a separate creatinine charge (82570) on top of the CMP. All 14 analytes are included in the panel price. If you see both the panel code and individual component codes on your bill, the individual charges should be removed.
CMP ordered when BMP was sufficient
A Basic Metabolic Panel (CPT 80048, $8.27 Medicare rate) includes 8 of the 14 CMP tests. If your doctor only needed to check kidney function and electrolytes (and not liver enzymes), a BMP would have been sufficient and cheaper. While the difference is small at Medicare rates ($10.33 vs $8.27), at provider charges the gap widens. Ask your doctor which panel is clinically necessary.
Hospital facility fee added to lab work
Some hospital outpatient labs add a facility fee or specimen collection fee on top of the test cost. Your bill may show a separate charge for venipuncture (CPT 36415) or specimen handling. While a small collection fee may be legitimate, a large facility fee on top of a $60 CMP charge is excessive. Compare with independent lab pricing.

Frequently Asked Questions
How much does a Comprehensive Metabolic Panel cost without insurance?
Without insurance, a CMP (CPT 80053) costs $30 to $100 at hospitals and clinics, with the national average at $59.85. However, direct-to-consumer labs like Quest, LabCorp walk-in, Ulta Lab Tests, and Jason Health offer a CMP for $10 to $30 without a doctor's order in many states. Medicare pays just $10.33 for this test.
What is the difference between a CMP and a BMP?
A Comprehensive Metabolic Panel (CPT 80053) includes 14 tests covering kidney function, liver function, electrolytes, and blood sugar. A Basic Metabolic Panel (CPT 80048) includes 8 of those tests, leaving out the liver function markers (ALP, ALT, AST, bilirubin, albumin, total protein). If your doctor only needs kidney and electrolyte values, a BMP is sufficient and slightly cheaper.
Can I order a CMP without a doctor?
In most states, yes. Direct-to-consumer lab services allow you to order blood tests without a physician's order. You pay online, visit a nearby lab location for the blood draw, and get results electronically. This is legal in most states, though a few (New York, New Jersey, Rhode Island) have restrictions on direct-to-consumer lab ordering.
Why is my CMP bill so much higher than the Medicare rate?
The provider's listed charge ($59.85 average) is not what most people actually pay. It is the "sticker price" that serves as a starting point for insurance negotiations. Medicare pays $10.33, and commercial insurers typically negotiate rates of $5 to $15 for a CMP. If you are uninsured and receive a bill for $60 or more, ask for the cash-pay rate or use a direct-to-consumer lab next time.
