Vesicoureter-reflux w reflux nephropathy w/o hydrourt, unsp

This code signifies kidney damage (nephropathy) resulting from the backward flow of urine from the bladder into the ureters and kidneys (vesicoureteral reflux), without an associated dilation of the ureter. It indicates a chronic kidney condition caused by this reflux, where the specific laterality or other details are not documented.

Use this code for patients diagnosed with reflux nephropathy due to vesicoureteral reflux when there is no mention of hydroureter. This diagnosis is typically supported by imaging studies (e.g., voiding cystourethrogram, renal ultrasound) demonstrating VUR and evidence of renal scarring or dysfunction. Documentation should explicitly state "reflux nephropathy" and confirm the absence of hydroureter.

• Ensure documentation specifies "without hydroureter" to differentiate from codes including hydroureter.
• This code is for unspecified laterality; if laterality (e.g., right, left, bilateral) is documented, a more specific code should be chosen.
• Consider sequencing this code after any underlying cause of the VUR if applicable and documented.
