By: Jeffrey Maser  Mar. 26, 2018

A Dexur study of inpatient Medicare claims data from CMS indicates that Dr. Margaret Laughlin Winkler of North Oaks Medical Center in Hammond accounted for 28 discharges with pneumonia in 2016, the most of any physician in Louisiana. Furthermore, Dr. Winkler accounted for 106 pneumonia discharges between 2013-2016, ranking 4th. In 2016, the 2nd highest volume physician was Dr. Kirit Patel of Willis - Knighton Medical Center in Shreveport with 27 discharges followed by Dr. Wen Liu, who also practices at Willis - Knighton, with 26 discharges. Dr. Cesar Ramirez-Astacio ranked 4th with 25 discharges, while splitting time between Iberia Medical Center in New Iberia and AMG Specialty Hospital - Lafayette. Five physicians had 22 discharges to tied for 5th in the rankings with three of these physicians practicing at Terrebonne General Medical Center in Houma.

Physicians were included in the rankings if they accounted for 11 or more pneumonia discharges between January - December 2016. Pneumonia is divided into three diagnosis related groups (DRG-193, DRG-194, and DRG-195) where DRG-193 and DRG-194 each accounted for nearly triple the national inpatient volume compared to DRG-195 in 2016. However, in the state of Louisiana, the discharges for DRG-193 and DRG-194 were only about double the volume of DRG-195 during this same year.
