Code Description

ICD-10 N13.71 is a billable code used to indicate a diagnosis of vesicoureteral-reflux without reflux nephropathy.

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 abnormal flow can lead to recurrent urinary tract infections (UTIs), pyelonephritis, and hydronephrosis, particularly in pediatric populations. In cases of VUR without reflux nephropathy, the kidneys remain functionally intact, and there is no evidence of kidney damage. The condition is often diagnosed through imaging studies such as a voiding cystourethrogram (VCUG) or renal ultrasound. Management typically involves monitoring, antibiotic prophylaxis to prevent UTIs, and in some cases, surgical intervention to correct the reflux. The absence of reflux nephropathy distinguishes this code from other related codes, emphasizing the importance of accurate diagnosis and documentation in coding practices.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between VUR with and without nephropathy
  • Need for precise documentation of imaging studies
  • Management plans that may vary significantly based on severity
  • Potential for co-existing conditions like pyelonephritis or hydronephrosis

Audit Risk Factors

  • Inadequate documentation of imaging results
  • Failure to specify the absence of nephropathy
  • Incorrect coding of associated conditions like pyelonephritis
  • Lack of clarity in treatment plans
