Glomerular disease in systemic lupus erythematosus

This code signifies kidney involvement, specifically glomerular disease, as a manifestation of systemic lupus erythematosus (SLE). It indicates that the patient's lupus has affected the filtering units of their kidneys, leading to various forms of glomerulonephritis.

Use this code when a patient with a confirmed diagnosis of SLE presents with documented evidence of glomerular disease, such as proteinuria, hematuria, or impaired renal function attributable to lupus nephritis. Supporting documentation should include pathology reports from kidney biopsies, urinalysis results, and physician notes detailing the diagnosis and management of lupus nephritis.

• Always sequence the underlying systemic lupus erythematosus (M32.10-M32.19) first, followed by this code to indicate the renal manifestation.
• Specify the type of lupus nephritis (e.g., diffuse proliferative, membranous) if documented, using more specific codes when available (e.g., N08.5 for glomerular disorders in systemic connective tissue disorders).
• Ensure documentation clearly links the glomerular disease to the systemic lupus erythematosus; avoid using this code for other causes of glomerular disease in a patient with SLE.
