ICD-10 code for urethra malformation

The ICD-10-CM code for urethra malformation is Q64.79 (Other congenital malformations of bladder and urethra). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Q64.79.

Within Q64.7, choose Q64.79 (Other congenital malformations of bladder and urethra) only when documentation doesn't support a more specific option: unspecified congenital malformation of bladder and urethra (Q64.70), congenital prolapse of urethra (Q64.71), congenital prolapse of urinary meatus (Q64.72), congenital urethrorectal fistula (Q64.73), Double urethra (Q64.74) and Double urinary meatus (Q64.75).

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.
