# CPT 83690

> Not at a published national rate. CPT 83690 carries status X (statutory exclusion) in the Q4 2018 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 lipase, the fat-digesting enzyme produced by the pancreas, in a blood sample. When the pancreas becomes inflamed the enzyme leaks into the bloodstream and the level rises sharply. It stays elevated longer than amylase does, which is why it has become the preferred blood test for pancreatitis, especially in patients who present a day or two after their pain started.
