About coding bridge
The ICD-10-CM code for bridge is Q24.5 (Malformation of coronary vessels).
Within Q24 (other congenital malformations of heart), Q24.5 is specifically for malformation of coronary vessels. Related codes cover Dextrocardia (Q24.0), Levocardia (Q24.1), cor triatriatum (Q24.2), pulmonary infundibular stenosis (Q24.3), congenital subaortic stenosis (Q24.4), congenital heart block (Q24.6), other specified congenital malformations of heart (Q24.8) and congenital malformation of heart, unspecified (Q24.9).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 306 (Cardiac Congenital and Valvular Disorders with MCC, relative weight 1.546) and DRG 307 (Cardiac Congenital and Valvular Disorders without MCC, relative weight 0.9148), in MDC 05 (Diseases and Disorders of the Circulatory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
