About coding urethra impervious
The ICD-10-CM code for urethra impervious is Q64.39 (Other atresia and stenosis of urethra and bladder neck).
Within Q64.3, choose Q64.39 (Other atresia and stenosis of urethra and bladder neck) only when documentation doesn't support a more specific option: congenital bladder neck obstruction (Q64.31), congenital stricture of urethra (Q64.32) and congenital stricture of urinary meatus (Q64.33).
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.
