About coding Albuminuria
The ICD-10-CM code for Albuminuria is R80.9 (Proteinuria, unspecified). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R80.9.
Within R80, choose R80.9 (unspecified) only when documentation doesn't support a more specific option: isolated proteinuria (R80.0), persistent proteinuria, unspecified (R80.1), orthostatic proteinuria, unspecified (R80.2), Bence Jones proteinuria (R80.3) and other proteinuria (R80.8).
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 695 (Kidney and Urinary Tract Signs and Symptoms with MCC, relative weight 1.1139) and DRG 696 (Kidney and Urinary Tract Signs and Symptoms without MCC, relative weight 0.6679), 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.
