About R80.2

R80.2 is the ICD-10-CM diagnosis code for orthostatic proteinuria, unspecified. It belongs to category R80 (proteinuria), block R80-R82 (abnormal findings on examination of urine, without diagnosis) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within R80, choose R80.2 (Orthostatic proteinuria, unspecified) only when documentation doesn't support a more specific option: isolated proteinuria (R80.0), persistent proteinuria, unspecified (R80.1), Bence Jones proteinuria (R80.3), other proteinuria (R80.8) and unspecified (R80.9).

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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 593.6 (postural proteinuria).
