About coding congenital orthotopic ureterocele
The ICD-10-CM code for congenital orthotopic ureterocele is Q62.31 (Congenital ureterocele, orthotopic). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Q62.31.
Within Q62.3 (other obstructive defects of renal pelvis and ureter), Q62.31 is specifically for congenital ureterocele, orthotopic. Related codes cover Cecoureterocele (Q62.32) and other obstructive defects of renal pelvis and ureter (Q62.39).
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.
