Acute pyelonephritis.
Medical necessity for N10 is established by the presence of signs, symptoms, and laboratory findings consistent with acute pyelonephritis. The documentation should support the diagnosis and the need for treatment to prevent or address complications such as sepsis or kidney damage. Specific payer guidelines may apply.
Clinicians responsible for diagnosing and managing N10 include primary care physicians, nephrologists (kidney specialists), and infectious disease specialists, depending on the severity and complexity of the case.
In simple words: Acute pyelonephritis is a sudden kidney infection that causes swelling and irritation.It's important to treat it to prevent serious complications.
Acute pyelonephritis is a bacterial infection causing inflammation of the kidneys.It affects the renal pelvis (where urine collects inside the kidney), as well as the kidney's functional tissue (parenchyma).
Example 1: A 30-year-old female presents with fever, chills, flank pain, and dysuria (painful urination). Urinalysis reveals white blood cells and bacteria, consistent with a urinary tract infection. The infection has ascended to the kidneys, resulting in acute pyelonephritis (N10)., A 65-year-old male with a history of diabetes and recurrent urinary tract infections develops acute pyelonephritis (N10) with sepsis.He requires hospitalization for intravenous antibiotics and supportive care., A 25-year-old pregnant woman experiencing flank pain and fever is diagnosed with acute pyelonephritis (N10).This requires careful management to protect both the mother and the developing fetus.
Documentation for N10 should include signs and symptoms (fever, chills, flank pain, dysuria), urinalysis results, and any imaging studies (such as ultrasound or CT scan) performed.The documentation should also include details regarding the severity of the infection, the causative organism (if identified), and any associated complications.
