ICD-10 code for idiopathic hematuria

The ICD-10-CM code for idiopathic hematuria is N02.9 (Recurrent and persistent hematuria with unspecified morphologic changes). The official index lists 14 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N02.9.

Within N02, choose N02.9 (with unspecified morphologic changes) only when documentation doesn't support a more specific option: with minor glomerular abnormality (N02.0), with focal and segmental glomerular lesions (N02.1), with diffuse membranous glomerulonephritis (N02.2), with diffuse mesangial proliferative glomerulonephritis (N02.3), with diffuse endocapillary proliferative glomerulonephritis (N02.4), with diffuse mesangiocapillary glomerulonephritis (N02.5), with dense deposit disease (N02.6), with diffuse crescentic glomerulonephritis (N02.7) and 3 more.

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 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.
