ICD Code N20.9

ICD code N20.9 is a diagnosis for a urinary stone (calculus) located somewhere in the urinary tract, but the exact location is not specified.

1. Patient presents with symptoms of renal colic, such as sudden onset of severe flank pain, which may radiate to the lower abdomen or groin.

2. Hematuria is detected, either gross or microscopic, during urinalysis.

3. Imaging studies (e.g., ultrasound, CT scan, or X-ray) reveal the presence of a urinary stone, but the exact location within the urinary tract cannot be determined.

4. Patient reports dysuria, urinary frequency, or urgency without evidence of infection.

5. There is a history of previous urinary calculi, but current diagnostic workup cannot specify the anatomical site of the stone.

6. No evidence of infection or other underlying urinary tract pathology is found to explain the symptoms.

7. Clinical documentation supports the presence of a urinary calculus, but lacks sufficient detail to assign a more specific code.
