ICD-10 code for kidney shock

The ICD-10-CM code for kidney shock is N17.0 (Acute kidney failure with tubular necrosis). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on N17.0.

Within N17 (acute kidney failure), N17.0 is specifically for acute kidney failure with tubular necrosis. Related codes cover with acute cortical necrosis (N17.1), with medullary necrosis (N17.2), other acute kidney failure (N17.8) and unspecified (N17.9).

As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" 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 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), DRG 684 (Renal Failure without CC/MCC, relative weight 0.6003) and 2 more, in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
