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

Our weekly documentation tip for clinicians.

By Timothy Brundage, MD

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”
