ICD-10 code for bladder exstrophy

The ICD-10-CM code for bladder exstrophy is Q64.10 (Exstrophy of urinary bladder, unspecified). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Q64.10.

Within Q64.1, choose Q64.10 (unspecified) only when documentation doesn't support a more specific option: Supravesical fissure of urinary bladder (Q64.11), cloacal exstrophy of urinary bladder (Q64.12) and other exstrophy of urinary bladder (Q64.19).

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.
