ICD Code N20.0

ICD code N20.0 is a medical classification used to specify a diagnosis of kidney stones, also known as renal calculi. This code is used by healthcare providers to document and communicate the presence of stones in the kidney, which can cause significant pain and potential complications if not treated.

When using the ICD code for Calculus of Kidney, consider the following diagnostic criteria and symptoms:

1. Flank Pain: Persistent or severe pain in the side and back, typically below the ribs, which may radiate to the lower abdomen and groin.

2. Hematuria: Presence of blood in the urine, which may be visible to the naked eye (gross hematuria) or detectable only under a microscope (microscopic hematuria).

3. Nausea and Vomiting: Episodes of nausea and vomiting that may accompany the pain.

4. Frequent Urination: An increased urge to urinate, often accompanied by discomfort or pain during urination.

5. Urinary Tract Infection (UTI) Symptoms: Symptoms such as burning sensation during urination, cloudy or foul-smelling urine, which may indicate a concurrent infection.

6. Imaging Confirmation: Evidence of kidney stones through imaging studies such as an ultrasound, CT scan, or X-ray.

7. Past Medical History: A history of kidney stones or conditions that predispose to stone formation, such as hyperparathyroidism or certain metabolic disorders.

8. Laboratory Findings: Abnormalities in blood or urine tests that suggest stone formation, such as elevated calcium or oxalate levels.

9. Family History: A family history of kidney stones, which may increase the likelihood of stone formation.

10. Dietary and Lifestyle Factors: Consideration of dietary habits, fluid intake, and lifestyle factors that may contribute to stone formation, such as high sodium or protein intake.

These criteria should be evaluated in conjunction with a healthcare provider's clinical judgment to determine the appropriate use of the ICD code for Calculus of Kidney.

For the ICD code N20.0, which pertains to calculus of kidney, the relevant CPT codes that may be applicable for treatment include:

1. 50080 - Percutaneous nephrolithotomy or pyelolithotomy, with or without dilation, endoscopy, lithotripsy, stenting, or basket extraction; up to 2 cm.

2. 50081 - Percutaneous nephrolithotomy or pyelolithotomy, with or without dilation, endoscopy, lithotripsy, stenting, or basket extraction; over 2 cm.

3. 50590 - Lithotripsy, extracorporeal shock wave.

4. 52356 - Cystourethroscopy, with ureteroscopy and/or pyeloscopy; with lithotripsy (ureteral catheterization is included).

5. 52353 - Cystourethroscopy, with ureteroscopy and/or pyeloscopy; with lithotripsy (ureteral catheterization is included).

6. 50561 - Laparoscopy, surgical; with removal of calculus/calculi from kidney, pelvis, or ureter.

These CPT codes represent various procedures that healthcare providers might use to treat kidney stones, depending on the size, location, and complexity of the stones. It's important for healthcare providers to select the appropriate CPT code based on the specific procedure performed.
