# CPT 85045

> Not at a published national rate. CPT 85045 carries status X (statutory exclusion) in the Q2 2015 release. The statutory definition of physician services does not include this item. Treat the blank amount as unpriced, not as $0.

## What it is

Counts reticulocytes - the youngest red blood cells, still carrying leftover traces of RNA - as a share of the red cells in a sample. The number reveals how hard the bone marrow is working to replace red cells, which is the pivotal question when sorting out the cause of anemia. This code covers the automated instrument count rather than a technologist counting stained cells on a slide.
