(just to list a few) the dr has ordered several lab tests to be done and u am familiar with them all except: 1. ANA by IFA AND 2. SEDRATE. now i think...sedrate measures inflamation in the body??? am i right? so the arthritis diagnosis (looking for ICD-9 codes) shoul pass for the labs diagnosis so that medicare will pay for his bloodwork.
