Sjogren syndrome with glomerular disease

This code identifies Sjögren syndrome, a chronic autoimmune disorder characterized by dry eyes and mouth, when it is complicated by kidney involvement specifically affecting the glomeruli. Glomerular disease in this context refers to inflammation or damage to the tiny filtering units of the kidneys.

Apply this code when documentation clearly states a diagnosis of Sjögren syndrome with co-occurring glomerular disease, such as glomerulonephritis or membranoproliferative glomerulonephritis, confirmed by renal biopsy or other diagnostic studies. This code is appropriate for patients experiencing renal manifestations directly attributed to their underlying Sjögren syndrome.

• Ensure documentation specifies glomerular involvement, not just general kidney disease, to support this specific code.
• Code any specific type of glomerular disease (e.g., M05.89 for other specified rheumatoid arthritis with other specified systemic involvement) as a secondary diagnosis if further detail is provided.
• Do not use this code for Sjögren syndrome without documented renal involvement or for kidney disease from other etiologies.
