80053 — Comprehensive metabolic panel
A standard 14-test blood panel — one of the most-billed lab codes. Common errors include duplicate charges and unbundled tests.
- Typical setting: Lab / outpatient
- National avg charge (illustrative): Insurance allowed $9–$30; cash $30–$200 depending on facility.
- Most-disputed reason: Duplicate billed alongside individual tests (unbundling).
What it means
What 80053 actually means
CPT 80053 is the Comprehensive Metabolic Panel — a single blood draw that tests 14 specific values (electrolytes, kidney function, liver function, glucose, calcium, etc.). Because it's a bundled code, none of those individual tests should be separately billed.
If you see 80053 on the bill alongside line items like 'BUN,' 'creatinine,' 'glucose,' or 'sodium,' that's an unbundling error and should be removed.
Common errors with this code
What goes wrong on real bills.
Most bills that look correct still contain at least one of these issues. Up to 49% of medical bills contain errors (CFPB).
- Unbundling — individual component tests billed separately on top of 80053.
- Duplicate 80053 charges from the same blood draw on the same date of service.
- Hospital outpatient lab pricing 5–10x higher than reference labs (LabCorp, Quest) for the identical test.
- Coded with a diagnosis that doesn't justify medical necessity, leading to insurer denial that gets passed to the patient.

2. Cross-check against the EOB. Compare what your insurer's Explanation of Benefits says you owe versus what the hospital is asking. They disagree more often than people think. Read the bill-vs-EOB guide →

How do I tell if my 80053 was unbundled?
On the itemized bill, look for line items with names like sodium, potassium, BUN, creatinine, glucose, calcium, total protein, albumin, ALT, AST, alkaline phosphatase, bilirubin, chloride, CO2. If any of those appear with their own charges next to 80053, that's an unbundling flag.
