Recur and perst hematur w diffus mesangial prolif glomrlneph

This code describes a specific type of kidney disease characterized by the presence of blood in the urine that repeatedly occurs and persists, coupled with inflammation and proliferation of mesangial cells throughout the glomeruli. This condition often indicates an underlying autoimmune or inflammatory process affecting the kidneys.

Use this code when documentation clearly states recurrent and persistent hematuria in conjunction with a biopsy-confirmed diagnosis of diffuse mesangial proliferative glomerulonephritis. This diagnosis is typically made by a nephrologist following renal biopsy and microscopic examination.

• Ensure the documentation specifies "diffuse" mesangial proliferative glomerulonephritis, as other forms exist.
• Do not use this code for isolated hematuria without a confirmed glomerular pathology.
• Consider sequencing this code as a primary diagnosis when it is the main reason for the encounter or admission.
