Hemorrhagic nephrosonephritis

This code represents a severe inflammatory condition of the kidneys characterized by both inflammation (nephritis) and bleeding (hemorrhage) within the renal tissue. It indicates a specific type of kidney disease where blood is present in the urine due to glomerular damage.

Use this code when documentation clearly indicates acute or chronic kidney inflammation accompanied by gross or microscopic hematuria, often associated with conditions like post-streptococcal glomerulonephritis or other immune-mediated renal diseases. Supporting documentation should specify both the inflammatory and hemorrhagic components of the renal involvement.

• Ensure documentation explicitly states "hemorrhagic" in conjunction with "nephritis" or "glomerulonephritis."
• Do not use for simple hematuria without evidence of underlying renal inflammation.
• Sequence this code as the primary diagnosis when it is the reason for the encounter, and code any underlying cause or associated systemic conditions secondarily.
