About coding congenital megaureter
The ICD-10-CM code for congenital megaureter is Q62.2 (Congenital megaureter).
Within Q62 (congenital obstructive defects of renal pelvis and congenital malformations of ureter), Q62.2 is specifically for congenital megaureter. Related codes cover congenital hydronephrosis (Q62.0), congenital occlusion of ureter (Q62.1), other obstructive defects of renal pelvis and ureter (Q62.3), agenesis of ureter (Q62.4), duplication of ureter (Q62.5), malposition of ureter (Q62.6), congenital vesico-uretero-renal reflux (Q62.7) and other congenital malformations of ureter (Q62.8).
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 698 (Other Kidney and Urinary Tract Diagnoses with MCC, relative weight 1.6398), DRG 699 (Other Kidney and Urinary Tract Diagnoses with CC, relative weight 1.0003) and DRG 700 (Other Kidney and Urinary Tract Diagnoses without CC/MCC, relative weight 0.6741), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
