Unbundled procedure

Billed for a lab panel — and its individual tests

A comprehensive metabolic panel (CMP) was ordered as a single blood draw. The bill lists the panel code, and then separately lists several of the individual component tests that the panel already includes.

Illustrative example built from BillMender's rules engine — not a real patient's bill, and not a claim about any specific hospital.

The bill

Comprehensive metabolic panelCPT 80053$145.00

Glucose test (component of CMP)CPT 82947$32.00

Potassium test (component of CMP)CPT 84132$28.00

Unbundled: component tests should be included in the panel code$60.00

CMS coding rules bundle the individual component tests into the panel code specifically so they can’t be billed twice. Charging the panel and its components separately — without a modifier documenting a genuinely distinct, separately-ordered test — is a textbook NCCI edit violation.

Basis: CMS National Correct Coding Initiative (NCCI) Procedure-to-Procedure edits, 42 CFR § 414.40.

Why this happens

Lab information systems often generate a line item per test performed, and if that feed isn’t reconciled against the panel code before billing, both show up on the statement.
