Acute kidney injury icd 10

Acute kidney injury (AKI) is a serious condition caused when the kidneys stop working suddenly, over a very short period of time (usually 48 hours or less). Several U.S. studies have indicated an increasing incidence of dialysis-treated acute kidney injury since the late 1990s, making AKI a common diagnosis seen by Criteria for Validating a Diagnosis of AKI The three main criteria used to validate a diagnosis of AKI: RIFLE Classification-Risk, Injury, Failure, Loss and End-stage kidney disease. When using the RIFLE Classification system for staging of severity, AKI represents stage III. AKIN Classification-Acute Kidney Injury Network This modified version of the RIFLE criteria was established in 2007. KDIGO Classification-Kidney Disease Improving Global Outcomes. Released in 2012, this classification adds to the RIFLE and AKIN criteria already in use. ICD-10 Codes for AKI N17 Acute kidney failure N17.0 Acute kidney failure with tubular necrosis N17.1 Acute kidney failure with acute cortical necrosis N17.2 Acute kidney failure with medullary necrosis N17.8 Other acute kidney failure N17.9 Acute kidney failure, unspecified • N17.0-Acute kidney failure with tubular necrosis. If the AKI has progressed to acute tubular necrosis (ATN), assign code N17.0. The documentation should be checked for terms such as renal tubular necrosis or tubular necrosis which are also used to describe ATN could also described using terms such as. • N17.1-Acute kidney failure with acute cortical necr...

Common Clinical Indicators for Acute Kidney Injury/Failure: • Decreased urine production-less than 0.5 mL per kg per hour for more than 6 hours • Edema • Confusion • Fatigue/lethargy • Nausea/vomiting/diarrhea • Abdominal pain • Metal taste in mouth • Increased BUN • Increased serum creatinine level-increased in greater or equal to 0.3 mg per dL or greater than or equal to 1.5 to twice the patient’s baseline • Increased potassium • Anemia • Proteinuria • Metabolic acidosis • Seizures • Coma • Abnormal GFR • Chest pain/pressure Common Clinical Indicators for Acute Tubular Necrosis: As we learned in the other parts of this series, acute tubular necrosis (ATN) is the most common cause of SEVERE acute renal failure, more so than acute cortical necrosis or medullary necrosis. In addition to the clinical indicators above, the following would be considered for a diagnosis of ATN: • Prolonged reduced renal blood flow (ischemic ATN) • Exposures to nephrotoxins and medications such as gentamycin, vancomycin, cyclosporine, tacrolimus, ace inhibitors, ARBS, cisplatin • Oliguric or on-oliguric • May require dialysis • Rhabdomyolysis, hemoglobinuria, aminoglycosides in toxic ATN • Sepsis, cardiogenic shock, hypovolemia, hypotension, vasoconstriction and postoperative status in ischemic ATN • Hypoperfusion causing cell injury in ischemic ATN • Acute decrease in GFR from tubular epithelial cell death and obstruction from casts and debris in the tubule lumen accompanied by a sudden increas...

Coding AKI/ARF There are several different codes that can be used to report the diagnosis of acute kidney injury and/or acute renal failure. This is one example of why diagnoses should not be coded by the use of only the Alphabetic Index within ICD-10-CM. It is imperative that coders also use the tabular before final determination of the code is made. If the coder only looks in the Alphabetic Index under injury | kidney | acute, the index goes to N17.9 (acute renal kidney failure, unspecified). If the type or cause of the AKI/ARF is further specified then N17.9 would not be appropriate. However, if the coder begins the search with the term “failure” there will be several selections for further specificity under failure | renal | acute. 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-. • N17.0—Acute kidney failure with tubular necrosis. Coders see ATN (acute tubular necrosis) documented in patient records often. This is a common diagnosis that a query is necessary for clarification. If the AKI has progressed to ATN then the code N17.0 is reported and not the code default in the Alphabetic Index for AKI. Other terms that may be used to describe ATN could be renal tubular necrosis or tubular necrosis. These are terms that ...

As part of our free webinar series, we conducted a webinar in December 2020 clarifying the diagnostic criteria for acute kidney injury (AKI), acute tubular necrosis (ATN), and acute on chronic kidney disease (CKD). We present the highlights below, including case studies and coding tips. Over the past twenty years there have been several attempts to come up with diagnostic standards for AKI/renal failure, most notably in JAMA (2003), at the 2004 RIFLE conference, and in the Acute Kidney Injury Network (AKIN) report (2007). Finally, in 2012 the Kidney Disease: Improving Global Outcomes (KDIGO) Acute Kidney Injury Guidelines combined the best of these previous efforts, providing an authoritative diagnostic standard for AKI that is now accepted world-wide. Get our CDI Pocket Guide ® for help with applying the diagnostic criteria for Acute Kidney Injury. Acute Kidney Injury (AKI) Seemingly small changes in creatinine reflect a significant loss of renal function: a creatinine increase of 1.5 times the baseline level corresponds to a 25% loss of renal function, and an increase to twice the baseline level corresponds to a 50% loss of renal function. Identifying and treating acute kidney injury as early as possible is therefore crucial. KDIGO specifies three different criteria for AKI, any one of which is sufficient for diagnosis: • Increase in creatinine to ≥ 1.5 times baseline (within a 7-day period), or • Increase in creatinine of ≥ 0.3 mg/dL within 48 hours, or • Urine output ...

Acute kidney injury (AKI) is a clinical syndrome manifested by a rapid or abrupt decline in kidney function and subsequent dysregulation of the body electrolytes and volume, and abnormal retention of nitrogenous waste. The widely accepted Kidney Disease: Improving Global Outcome (KDIGO) definition of AKI is based on the change of serum creatinine and urine output, as follows [ • Symptoms and signs Most patients with AKI have no clinical symptoms related to AKI and are diagnosed on the basis of a routine laboratory blood test. Depending on the degree of kidney function impairment and the duration, however, they might have hypertension, edema, decreased urine output, shortness of breath, anorexia, nausea, sleep disturbances and altered mental status. When evaluating a patient with AKI, the signs listed below may help in identifying the etiology associated with AKI. Furthermore, a rise in serum creatinine might not always be related to a decrease in kidney function; certain medications (eg, cimetidine, trimethoprim, Poly ADP-ribose polymerase [PARP] inhibitors, and cyclin-dependent kinase 4 and 6 [CDK4/6] inhibitors) caninhibit the kidney’s tubular secretion of creatinine independent of glomerular filtration rate (GFR). Arise in the BUN level can also occur without renal injury, as a result of gastrointestinal (GI) or mucosal bleeding, steroid use, or protein loading. Therefore, a careful inventory must be taken before concluding that a kidney injury is present. (See Oliguric...
