Acute kidney failure with tubular necrosis. N17.0 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2019 edition of ICD-10-CM N17.0 became effective on October 1, 2018.
When coding AKI/ARF, there are instructional notes within the ICD-10-CM Index for coders to follow as well as Exclude1 and Excludes2 notes. When a cause for the AKI/ARF has been identified the underlying condition/cause should be reported also. Traumatic kidney injuries are reported with codes from S37.0-.
Acute drug induced tubulointerstitial nephritis; Acute interstitial nephritis; Acute pyelonephritis (kidney infection); Acute infectious interstitial nephritis; Acute pyelitis; Acute tubulo-interstitial nephritis; Hemoglobin nephrosis; Myoglobin nephrosis; code (B95-B97), to identify infectious agent.
N17.1—Acute kidney failure with acute cortical necrosis. This isn’t as commonly documented as ATN but coders will see this. If the AKI has progressed to acute cortical necrosis then N17.1 is reported and not the code default in the Alphabetic Index for AKI.

Acute tubular necrosis (ATN) is the most common cause of acute kidney injury (AKI) in the renal category (that is, AKI in which the pathology lies within the kidney itself). The term ATN is actually a misnomer, as there is minimal cell necrosis and the damage is not limited to tubules.
What is acute tubular necrosis? Acute tubular necrosis is a condition that causes the lack of oxygen and blood flow to the kidneys, damaging them. Tube-shaped structures in the kidneys, called tubules, filter out waste products and fluid. These structures are damaged in acute tubular necrosis.
Etiologically, this common condition can be categorized as prerenal, intrinsic or postrenal. Most patients have pre-renal acute renal failure or acute tubular necrosis (a type of intrinsic acute renal failure that is usually caused by ischemia or toxins).
Because necrosis is often not present, the term acute tubular injury (ATI) is preferred by pathologists over the older name acute tubular necrosis (ATN). ATN presents with acute kidney injury (AKI) and is one of the most common causes of AKI....Acute tubular necrosisSpecialtyNephrology
As a clinical condition characterized by an acute onset of kidney injury, the principal differential diagnosis of AIN is its differentiation from ATN.
The two major causes of AKI that occur in the hospital are prerenal disease and acute tubular necrosis (ATN). Together, they account for approximately 65 to 75 percent of cases of AKI. (See 'Frequency of prerenal disease and acute tubular necrosis as a cause of AKI' below.)
Acute tubular necrosis is kidney injury caused by damage to the kidney tubule cells (kidney cells that reabsorb fluid and minerals from urine as it forms). Common causes are low blood flow to the kidneys (such as caused by low blood pressure), drugs that damage the kidneys, and severe bodywide infections.
Acute tubular necrosis causes injury to the renal tubular cells, resulting in sloughing of cells into the lumen. One mechanism leading to AKI is the obstruction of tubules by these sloughed cells.
Post-renal AKI occurs after acute obstruction of the urinary flow, which increases intra-tubular pressure and thus decreases GFR. 63. In addition, acute urinary tract obstruction can lead to impaired renal blood flow and inflammatory processes that also contribute to diminished GFR.
Acute tubular necrosis (ATN) is a medical condition involving the death of tubular epithelial cells that form the renal tubules of the kidneys. ATN presents with acute kidney injury (AKI) and is one of the most common causes of AKI. Common causes of ATN include low blood pressure and use of nephrotoxic drugs.

This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 584.5 was previously used, N17.0 is the appropriate modern ICD10 code.
This is caused by infarction involving the medulla and referred to as necrotizing papillitis. N17.8—Other acute kidney failure.
Other terms that may be used to describe acute cortical necrosis can be cortical necrosis and renal cortical necrosis. This is a rare cause of AKI and is due to ischemic necrosis of the renal cortex. This is typically caused by diminished/reduced renal arterial perfusion. Intravascular coagulation, vascular spasm and microvascular injury are ...
ATN occurs when there is damage to the kidney tubule cells. These are the cells that reabsorb fluid and minerals in the kidney from urine as it is forming. When this occurs, there is a lack of oxygen reaching the cells of your kidneys. N17.1—Acute kidney failure with acute cortical necrosis.
Other terms that may be used to describe ATN could be renal tubular necrosis or tubular necrosis. These are terms that should be searched for when AKI is documented to see if there could be further specificity in code assignment. ATN occurs when there is damage to the kidney tubule cells.
