Recur and perst IgA nephr with diffus membranous glomrlneph

This code signifies a specific and severe form of kidney disease characterized by the deposition of immunoglobulin A in the glomeruli, which has returned after treatment or continues despite intervention, and is accompanied by widespread thickening of the glomerular basement membrane. This indicates a complex and often progressive renal pathology.

Use this code when documentation explicitly states recurrent or persistent IgA nephropathy co-occurring with diffuse membranous glomerulonephritis, typically confirmed by renal biopsy. This applies to patients experiencing ongoing or relapsing disease activity with both histological features present.

• Ensure documentation clearly specifies both "recurrent and persistent" and "diffuse membranous glomerulonephritis" in conjunction with IgA nephropathy.
• Do not use this code if only one of the conditions (IgA nephropathy or membranous glomerulonephritis) is present, or if the IgA nephropathy is not explicitly recurrent/persistent.
• Review biopsy reports and nephrology notes for precise histological findings and disease activity status.
