Code Description

ICD-10 N13.739 is a billable code used to indicate a diagnosis of vesicoureteral-reflux with reflux nephropathy with hydroureter, unspecified.

Key Diagnostic Point:

Vesicoureteral reflux (VUR) is a condition where urine flows backward from the bladder into the ureters and potentially into the kidneys. This can lead to recurrent urinary tract infections (UTIs) and can cause reflux nephropathy, which is characterized by kidney damage due to the backflow of urine. In cases where VUR is associated with hydroureter, there is dilation of the ureter due to the increased pressure from the refluxed urine. This condition can lead to pyelonephritis, an infection of the kidney, and interstitial nephritis, which is inflammation of the kidney's interstitial tissue. Patients may present with symptoms such as flank pain, fever, and dysuria. Management often includes antibiotic therapy to prevent UTIs and surgical interventions in severe cases. Drug-induced nephropathy may also be a concern, particularly if nephrotoxic medications are used in patients with compromised renal function. Accurate coding is essential for proper treatment and reimbursement.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between types of nephropathy and their causes
  • Understanding the relationship between VUR and recurrent UTIs
  • Identifying the presence of hydroureter and its implications
  • Navigating the documentation requirements for multiple specialties

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings
  • Failure to document the relationship between VUR and nephropathy
  • Misclassification of the severity of the condition
  • Lack of follow-up documentation for recurrent infections

Frequently Asked Questions

What is the primary cause of vesicoureteral reflux?

The primary cause of vesicoureteral reflux is a congenital defect in the ureterovesical junction, which fails to close properly during bladder contraction, allowing urine to flow back into the ureters.
