About C68.8
C68.8 is the ICD-10-CM diagnosis code for malignant neoplasm of overlapping sites of urinary organs. It belongs to category C68 (malignant neoplasm of other and unspecified urinary organs), block C64-C68 (malignant neoplasms of urinary tract) and chapter 2 (neoplasms). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within C68 (malignant neoplasm of other and unspecified urinary organs), C68.8 is specifically for malignant neoplasm of overlapping sites of urinary organs. Related codes cover urethra (C68.0), paraurethral glands (C68.1) and urinary organ, unspecified (C68.9).
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 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.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 189.8 (malignant neoplasm of other specified sites of urinary organs).
