CPT code 84484

What does CPT code 84484 mean on a medical bill?

Troponin is the blood test for heart muscle damage, and it is the reason chest pain visits take hours: it is usually drawn two or three times, spaced apart, to see whether the number is moving. Several lines for this test on one bill is normal and expected. What should match is the number of lines on the bill and the number of results in your record.

What does CPT code 84484 usually cost?

Billed per result, so a chest pain workup normally produces more than one line, and each draw may carry its own small collection charge. A high-sensitivity version exists and is billed under its own code, so check which one your report names.

What should I watch out for with CPT code 84484?

• More troponin lines than results in your lab report
• Both the standard and the high-sensitivity version billed from one sample
• Repeat troponins billed after you were already discharged
