Documentation Tip of the Week: Acute Tubular Necrosis (ATN)

Documentation which captures ATN adds to the severity of illness of your patient. Consider documenting ATN when acute renal failure lasts > 3 days after fluid resuscitation.

Causes of ATN:

  • Contrast nephropathy (following CT scan, cardiac catheterization)
  • Medications (Gentamicin, Aminoglycosides)
  • Prolonged ischemia, shock
  • Hypotension
  • Rhabdomyolysis
  • Hypovolemia

Documentation Examples:
  • “Acute renal failure secondary to probable ATN”
