ICD-10 code for ureter malformation

The ICD-10-CM code for ureter malformation is Q62.8 (Other congenital malformations of ureter). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Q62.8.

Within Q62, choose Q62.8 (Other congenital malformations of ureter) only when documentation doesn't support a more specific option: congenital hydronephrosis (Q62.0), congenital occlusion of ureter (Q62.1), congenital megaureter (Q62.2), 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) and congenital vesico-uretero-renal reflux (Q62.7).

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.
