About coding ureter ectopic
The ICD-10-CM code for ureter ectopic is Q62.63 (Anomalous implantation of ureter).
Within Q62.6 (malposition of ureter), Q62.63 is specifically for anomalous implantation of ureter. Related codes cover unspecified (Q62.60), deviation of ureter (Q62.61), displacement of ureter (Q62.62) and other malposition of ureter (Q62.69).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
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.
