ICD-10 code for ureter atresia

The ICD-10-CM code for ureter atresia is Q62.10 (Congenital occlusion of ureter, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Q62.10.

Within Q62.1, choose Q62.10 (unspecified) only when documentation doesn't support a more specific option: opelvic junction (Q62.11) and ovesical orifice (Q62.12).

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.
