Unspecified hydronephrosis
ICD-10 N13.30 is a billable code used to indicate a diagnosis of unspecified hydronephrosis.
Unspecified hydronephrosis refers to the dilation of the renal pelvis and calyces due to the accumulation of urine, which can occur when there is an obstruction in the urinary tract. This condition can arise from various causes, including urinary tract infections (UTIs), kidney stones, or anatomical abnormalities. In some cases, hydronephrosis may be associated with pyelonephritis, an infection of the kidney that can lead to interstitial nephritis, characterized by inflammation of the kidney's interstitial tissue. Drug-induced nephropathy can also contribute to hydronephrosis, particularly when medications affect renal function or urinary flow. The management of hydronephrosis often involves addressing the underlying cause, which may include the use of antibiotics for UTIs or surgical interventions for obstructions. Accurate diagnosis and treatment are crucial to prevent complications such as renal damage or chronic kidney disease. Clinicians must carefully evaluate symptoms, imaging studies, and laboratory results to determine the appropriate course of action.
Detailed history of urinary symptoms, imaging results, and treatment plans.
Patients presenting with flank pain, hematuria, or recurrent UTIs.
Ensure documentation reflects the cause of hydronephrosis and any interventions performed.
Comprehensive renal function tests, imaging studies, and assessment of kidney function.
Patients with chronic kidney disease or acute kidney injury related to hydronephrosis.
Document any renal impairment and the impact of hydronephrosis on kidney function.
Used to evaluate hydronephrosis in patients with flank pain.
Document indications for the ultrasound and findings.
Urologists may frequently order this imaging for diagnosis.
Use N13.30 when the cause of hydronephrosis is not documented or cannot be determined. Ensure that all clinical information supports the use of this unspecified code.
