Understand prerenal azotemia diagnosis, causes, and treatment. Find information on clinical documentation, medical coding, ICD-10 codes, and SNOMED CT codes related to prerenal acute kidney injury and renal failure. Learn about lab values like BUN creatinine ratio, elevated creatinine, and decreased GFR in prerenal azotemia. Explore resources for healthcare professionals, including clinical practice guidelines and differential diagnosis considerations for dehydration, hypovolemia, and reduced renal blood flow.

Coding Prerenal Azotemia as unspecified AKI when a specific underlying cause is documented leads to inaccurate severity and quality reporting.
Incorrectly coding dehydration as the sole cause without linking it to Prerenal Azotemia misses the acuity of renal dysfunction.
Failing to capture comorbidities like CHF or hypotension contributing to Prerenal Azotemia impacts risk adjustment and resource allocation.
Patient presents with prerenal azotemia, likely secondary to [documented cause, e.g., dehydration, heart failure, hypovolemia]. Symptoms include [list pertinent symptoms, e.g., decreased urine output, fatigue, dizziness]. Physical examination reveals [document relevant findings, e.g., hypotension, tachycardia, dry mucous membranes]. Laboratory findings demonstrate elevated blood urea nitrogen (BUN) and creatinine, with a BUNcreatinine ratio greater than 201. Urinalysis shows [describe findings, e.g., high urine specific gravity, low fractional excretion of sodium]. These findings are consistent with decreased renal perfusion. Differential diagnosis includes intrinsic acute kidney injury and postrenal azotemia. However, the clinical picture and laboratory data support the diagnosis of prerenal acute kidney injury (AKI). Treatment plan includes aggressive fluid resuscitation with [specify fluid type and rate], monitoring of urine output, and correction of the underlying cause. Patient education provided regarding the importance of hydration and follow-up care. Prognosis is generally favorable with prompt treatment and restoration of renal perfusion. ICD-10 code N17.8, acute kidney failure, unspecified, is used for prerenal azotemia until the underlying cause is addressed and a more specific code can be applied. Monitoring for progression to acute tubular necrosis is crucial.
