About coding cystectomy status
The ICD-10-CM code for cystectomy status is Z90.6 (Acquired absence of other parts of urinary tract).
Within Z90, choose Z90.6 (other parts of urinary tract) only when documentation doesn't support a more specific option: part of head and neck (Z90.0), breast and nipple (Z90.1), lung [part of] (Z90.2), stomach [part of] (Z90.3), other specified parts of digestive tract (Z90.4), kidney (Z90.5), genital organ(s) (Z90.7) and other organs (Z90.8).
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.
