Updated estimates for the burden of chronic limb-threatening ischemia in the Medicare population: Presented at the Forty-ninth Annual Symposium of the Society for Clinical Vascular Surgery, Las Vegas, Nevada, March 19-23, 2022.

Abstract

Objective: Estimates of chronic limb-threatening ischemia (CLTI) based on diagnosis codes of the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) suggest a prevalence of 0.23%-0.32% and incidence of 0.20%-0.26% among Medicare patients. ICD-10-CM includes 144 CLTI diagnosis codes, allowing improved specificity in identifying affected patients. We sought to use ICD-10-CM diagnosis codes to determine the prevalence of CLTI among Medicare patients and describe the patient cohort affected by this condition.
