# CPT 83880

> Not at a published national rate. CPT 83880 carries status X (statutory exclusion) in the Q4 2022 release. The statutory definition of physician services does not include this item. Treat the blank amount as unpriced, not as $0.

## What it is

Measures a natriuretic peptide - either BNP or the related NT-proBNP fragment - a hormone the heart releases when its chambers are stretched by too much pressure or volume. A high level points toward heart failure, and a low level is very good at ruling it out. That makes it one of the fastest ways to tell whether someone's breathlessness is coming from the heart or from the lungs, a distinction that changes treatment immediately.
