50220

Nephrectomy, including partial ureterectomy, any open approach including rib resection

CPT code 50220 describes an open surgical procedure for the removal of a kidney (nephrectomy), which may also include the removal of a portion of the ipsilateral ureter (partial ureterectomy). This procedure can be performed using any open surgical approach, such as a flank, subcostal, or thoracoabdominal incision, and may involve rib resection to facilitate adequate surgical access to the kidney. The service encompasses the full removal of the kidney and any associated partial ureterectomy, and is typically indicated for a diseased or severely damaged kidney that requires excision.

Clinical Indications

  • Malignant neoplasm of the kidney (e.g., renal cell carcinoma) not amenable to partial nephrectomy.
  • Severe, irreparable kidney trauma.
  • Non-functional kidney causing symptoms (e.g., pain, hypertension) or recurrent infections.
  • End-stage hydronephrosis with loss of renal function.
  • Xanthogranulomatous pyelonephritis or other severe, refractory kidney infections.
  • Large, symptomatic benign renal tumors (e.g., angiomyolipoma) not amenable to kidney-sparing surgery.
  • Irreversibly damaged kidney due to renovascular disease or severe congenital anomalies.

Procedure Steps

  1. Patient positioning (e.g., lateral decubitus for flank approach, supine for anterior approach).
  2. Preparation and sterile draping of the surgical field.
  3. Creation of an open incision (e.g., flank, subcostal, thoracoabdominal), potentially involving rib resection for optimal exposure.
  4. Dissection through muscle and fascia layers to expose the retroperitoneal space and Gerota's fascia surrounding the kidney.
  5. Identification and meticulous dissection of the renal hilum, including the renal artery and renal vein.
  6. Ligation and division of the renal artery and vein.
  7. Identification, mobilization, ligation, and division of the ureter (with partial ureterectomy if indicated).
  8. Mobilization and removal of the entire kidney.
  9. Thorough hemostasis and irrigation of the surgical site.
  10. Placement of a surgical drain, if deemed necessary by the surgeon.
  11. Layered closure of the incision.

Coding Guidelines

  • This code has a 90-day global surgical period, covering all routine pre-operative, intra-operative, and post-operative care within that timeframe.
  • The descriptor explicitly includes 'partial ureterectomy' and 'any open approach including rib resection,' therefore, these components are integral to the procedure and should not be coded separately.
  • For bilateral nephrectomy (rare for therapeutic purposes, more common in specific scenarios like prior to kidney transplant in polycystic kidney disease patients), append Modifier 50 (Bilateral Procedure) to 50220.
  • If a radical nephrectomy is performed (removal of kidney, adrenal gland, perinephric fat, and regional lymph nodes), code 50230 should be used instead.
  • Documentation must clearly specify the medical necessity for the nephrectomy, the surgical approach, and the pathology or condition necessitating the procedure.
