About coding bladder papilloma

The ICD-10-CM code for bladder papilloma is D41.4 (Neoplasm of uncertain behavior of bladder).

Within D41 (neoplasm of uncertain behavior of urinary organs), D41.4 is specifically for neoplasm of uncertain behavior of bladder. Related codes cover kidney (D41.0), renal pelvis (D41.1), ureter (D41.2), urethra (D41.3), other specified urinary organs (D41.8) and unspecified urinary organ (D41.9).

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.
