ICD Code N13.9

ICD code N13.9 is obstructive and reflux uropathy, unspecified, which refers to a condition where urine flow is blocked or flows backward in the urinary tract, but the exact cause or location is not specified.

1. Evidence of urinary tract obstruction or reflux identified through imaging studies (e.g., ultrasound, CT scan, MRI) without a specified underlying cause

2. Clinical symptoms such as flank pain, lower abdominal pain, or urinary retention

3. Laboratory findings indicating impaired renal function (e.g., elevated serum creatinine, decreased glomerular filtration rate)

4. Absence of a more specific diagnosis for the cause of the obstruction or reflux after appropriate evaluation

5. Documentation of hydronephrosis or hydroureter without a clearly identified etiology

6. Recurrent urinary tract infections associated with evidence of urinary tract obstruction or reflux

7. No documentation of congenital, acquired, or anatomical abnormalities as the specific cause

Relevant CPT codes that may be used to treat ICD code N13.9 include:

- 52000 (Cystourethroscopy)

- 52332 (Cystourethroscopy, with insertion of indwelling ureteral stent)

- 50590 (Lithotripsy, extracorporeal shock wave)

- 50435 (Percutaneous nephrostolithotomy or pyelostolithotomy, with or without dilation)

- 50392 (Introduction of intracatheter or stent into ureter)

- 50605 (Ureterotomy, with exploration, drainage, or removal of calculus)

- 52310 (Cystourethroscopy with removal of foreign body, calculus, or ureteral stent from urethra or bladder)

- 52351 (Cystourethroscopy with ureteroscopy and/or pyeloscopy; diagnostic)

- 52352 (Cystourethroscopy with ureteroscopy and/or pyeloscopy; with biopsy)

- 52353 (Cystourethroscopy with ureteroscopy and/or pyeloscopy; with lithotripsy)

These CPT codes are commonly associated with the management and treatment of N13.9. Proper code selection should be based on the specific clinical scenario and procedures performed.
