CPT organ or disease-oriented panels, such as the basic metabolic panel 80048, list a fixed set of component tests. When a laboratory performs every test named in a panel on one date of service, how does CPT direct the coder to report the work?
80048 Basic metabolic panel
component example: 82947 Glucose, 84520 Urea nitrogen, 82565 Creatinine- AReport each component test with its individual code and append modifier 59 to show the tests were distinct.
- BReport the panel code and also report each component test individually to capture the full laboratory work.
- CReport the single panel code, because CPT lists the panel code once every named component test is performed on that date. Correct
- DReport the component test carrying the highest relative value and list the remaining tests as add-on codes.
Why A is wrong: This looks correct because modifier 59 does separate bundled services, but billing the components individually to unbundle a completed panel is exactly what CPT panel rules forbid.
Why B is wrong: Reporting both double counts the same tests; the panel code already includes every component, so adding them again is duplicate billing, not fuller capture.
Why C is correct: Correct: CPT panel definitions require the panel code when all listed components are performed, which prevents unbundling and reflects the intended bundled reimbursement.
Why D is wrong: Panel components are not structured as a primary test plus add-on codes, so this misapplies add-on logic and would omit the correct single panel code.
