Recur and perst IgA nephr with focal and seg glomerular lesn

This code signifies a chronic kidney disease characterized by the deposition of immunoglobulin A in the glomeruli, specifically presenting with recurrent episodes and persistent damage. The glomerular lesions are focal (affecting some glomeruli) and segmental (affecting parts of those glomeruli), indicating a specific pattern of kidney injury. This condition can lead to progressive kidney dysfunction.

Apply this code when documentation confirms a diagnosis of IgA nephropathy that is explicitly stated as recurrent and persistent, and a kidney biopsy report or pathology findings specify focal and segmental glomerular lesions. This code is appropriate for patients with ongoing disease activity and specific histological findings.

• Ensure documentation clearly distinguishes between recurrent/persistent IgA nephropathy and acute or resolving forms.
• Verify the presence of "focal and segmental" lesions from pathology reports; do not assume based on a general IgA nephropathy diagnosis.
• Consider sequencing this code with codes for associated chronic kidney disease stages if documented.
