About coding Ischuria
The ICD-10-CM code for Ischuria is R34 (Anuria and oliguria).
Don't report R34 together with the conditions in its Excludes1 note: anuria and oliguria complicating abortion or ectopic or molar pregnancy (O00-O07, O08.4), anuria and oliguria complicating pregnancy (O26.83-) and anuria and oliguria complicating the puerperium (O90.49).
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 673 (Other Kidney and Urinary Tract Procedures with MCC, relative weight 4.2525), DRG 674 (Other Kidney and Urinary Tract Procedures with CC, relative weight 2.2504), DRG 675 (Other Kidney and Urinary Tract Procedures without CC/MCC, relative weight 1.5887), DRG 682 (Renal Failure with MCC, relative weight 1.4656), DRG 683 (Renal Failure with CC, relative weight 0.8647) and DRG 684 (Renal Failure without CC/MCC, relative weight 0.6003), 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.
Don't confuse with (Excludes1 for R34)
