ICD-10 code for bladder cancer

The ICD-10-CM code for bladder cancer is C67.9 (Malignant neoplasm of bladder, unspecified). The official index lists 9 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on C67.9.

Within C67, choose C67.9 (unspecified) only when documentation doesn't support a more specific option: trigone of bladder (C67.0), dome of bladder (C67.1), lateral wall of bladder (C67.2), anterior wall of bladder (C67.3), posterior wall of bladder (C67.4), neck (C67.5), ureteric orifice (C67.6), urachus (C67.7) and 1 more.

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 656 (Kidney and Ureter Procedures for Neoplasm with MCC, relative weight 3.2786), DRG 657 (Kidney and Ureter Procedures for Neoplasm with CC, relative weight 1.8365), DRG 658 (Kidney and Ureter Procedures for Neoplasm without CC/MCC, relative weight 1.538), DRG 686 (Kidney and Urinary Tract Neoplasms with MCC, relative weight 1.7237), DRG 687 (Kidney and Urinary Tract Neoplasms with CC, relative weight 0.9957) and DRG 688 (Kidney and Urinary Tract Neoplasms without CC/MCC, relative weight 0.7333), 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.
