About coding glomerular in disorder
The ICD-10-CM code for glomerular in disorder is N05.9 (Unspecified nephritic syndrome with unspecified morphologic changes). The official index lists 22 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N05.9.
Within N05, choose N05.9 (with unspecified morphologic changes) only when documentation doesn't support a more specific option: with minor glomerular abnormality (N05.0), with focal and segmental glomerular lesions (N05.1), with diffuse membranous glomerulonephritis (N05.2), with diffuse mesangial proliferative glomerulonephritis (N05.3), with diffuse endocapillary proliferative glomerulonephritis (N05.4), with diffuse mesangiocapillary glomerulonephritis (N05.5), with dense deposit disease (N05.6), with diffuse crescentic glomerulonephritis (N05.7) and 2 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 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.
