ICD-10 code for renal stasis

The ICD-10-CM code for renal stasis is N19 (Unspecified kidney failure). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on N19.

Don't report N19 together with the conditions in its Excludes1 note: acute kidney failure (N17.-), chronic kidney disease (N18.-), chronic uremia (N18.9), extrarenal uremia (R39.2) and 3 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 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.
