About coding Vesicourethral orifice stenosis
The ICD-10-CM code for Vesicourethral orifice stenosis is Q64.31 (Congenital bladder neck obstruction).
Within Q64.3 (other atresia and stenosis of urethra and bladder neck), Q64.31 is specifically for congenital bladder neck obstruction. Related codes cover congenital stricture of urethra (Q64.32), congenital stricture of urinary meatus (Q64.33) and other atresia and stenosis of urethra and bladder neck (Q64.39).
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.
