Other and unspecified hydronephrosis
ICD-10 N13.3 is a billable code used to indicate a diagnosis of other and unspecified hydronephrosis.
Hydronephrosis is a condition characterized by the swelling of a kidney due to a build-up of urine. This occurs when there is an obstruction in the urinary tract that prevents urine from draining properly from the kidney to the bladder. Other and unspecified hydronephrosis (ICD-10 code N13.3) encompasses cases where the specific cause of the hydronephrosis is not clearly defined or documented. It can be associated with various underlying conditions, including pyelonephritis, interstitial nephritis, and urinary tract infections (UTIs). Pyelonephritis, an infection of the kidney, can lead to hydronephrosis if the infection causes swelling and obstruction. Interstitial nephritis, which involves inflammation of the kidney's interstitial tissue, can also contribute to urinary obstruction. Drug-induced nephropathy, often resulting from medications that affect kidney function, may lead to hydronephrosis as well. Effective management often includes antibiotic therapy for infections, addressing the underlying cause of obstruction, and monitoring kidney function to prevent further complications.
Detailed history of renal function, imaging studies, and lab results.
Patients presenting with flank pain, hematuria, or recurrent UTIs.
Ensure clear documentation of any imaging findings and the rationale for diagnosis.
Surgical notes, imaging results, and post-operative follow-up.
Patients with obstructive uropathy requiring surgical intervention.
Document any interventions performed to relieve obstruction.
Used to evaluate hydronephrosis in patients with flank pain.
Document indications for ultrasound and findings.
Nephrology and urology may require specific imaging protocols.
Common causes include kidney stones, tumors, strictures, and urinary tract infections. Each of these can lead to obstruction and subsequent hydronephrosis.
Diagnosis typically involves imaging studies such as ultrasound or CT scans, along with a thorough clinical history and physical examination.
