Interpretive Data: Patients with higher hs-CRP concentrations are more likely to develop stroke, myocardial infarction, and severe peripheral vascular disease. 

hs-CRP results are used to assign risk as follows:
< 1.0 mg/L lowest tertile, lowest risk.
1.0-3.0 mg/L middle tertile, average risk.
> 3.0 mg/L highest tertile, highest risk.

CRP is a nonspecific marker of inflammation and a variety of conditions other than atherosclerosis may cause elevated levels.
CPT Code(s): 86141
