About coding bladder disease
The ICD-10-CM code for bladder disease is N32.9 (Bladder disorder, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N32.9.
Within N32, choose N32.9 (Bladder disorder, unspecified) only when documentation doesn't support a more specific option: Bladder-neck obstruction (N32.0), Vesicointestinal fistula (N32.1), Vesical fistula, not elsewhere classified (N32.2), diverticulum of bladder (N32.3) and other specified disorders of bladder (N32.8).
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.
