2025 CPT code 50240

Partial nephrectomy; removal of only a diseased or infected portion of the kidney.

Adhere to the current CPT coding guidelines and any payer-specific coding instructions.Proper documentation is essential for accurate coding and reimbursement.

Modifiers may be applicable depending on the circumstances of the procedure (e.g., 51 for multiple procedures, 59 for distinct procedural service, 22 for increased procedural services etc.).Consult the CPT manual for specific modifier guidelines.

Medical necessity for a partial nephrectomy is established when a patient has a localized renal mass or area of infection that can be safely removed without compromising renal function. The procedure is generally preferred over radical nephrectomy when possible, to preserve renal function and reduce the risk of complications.

The surgeon is responsible for performing the partial nephrectomy, including making the incision, exposing the kidney, identifying and removing the diseased tissue, and repairing the kidney and closing the incision. Anesthesiologist provides anesthesia during the procedure.

IMPORTANT:For laparoscopic partial nephrectomy, use 50543.For excision of retroperitoneal tumor or cyst, see 49203-49205. For laparoscopic ablation of renal mass lesion(s), use 50542.Use CPT® code 50225 if the same surgery has been performed on the same kidney in the past. Use CPT® code 50230 if radical nephrectomy has been performed. Use CPT® code 50234 if nephrectomy was performed with total removal of ureter and bladder cuff through the same incision. Use CPT® code 50236 if nephrectomy was performed with total removal of ureter and bladder cuff through separate incisions. Use CPT® codes 5030050320 for donor nephrectomy. Use CPT® code 50340 for recipient nephrectomy.

In simple words: This surgery removes only the sick part of a kidney, leaving the healthy part intact.It's done to preserve kidney function as much as possible.

Partial nephrectomy involves the surgical removal of a diseased or infected portion of the kidney, preserving the remaining healthy kidney tissue.The procedure is typically performed under general anesthesia. An incision is made, the kidney exposed, and the affected area identified using ultrasound or other imaging techniques.The diseased tissue is then carefully excised, and the remaining kidney tissue is repaired and the incision closed. This approach is preferred when possible to maintain renal function.

Example 1: A 60-year-old male patient presents with a small renal tumor (less than 4cm) detected during a routine ultrasound.A partial nephrectomy is performed to remove the tumor while preserving renal function., A 45-year-old female patient with a history of kidney infection and localized kidney damage undergoes a partial nephrectomy to remove the infected portion of the kidney., A 72-year-old male patient with a solitary kidney and a small renal tumor is a candidate for partial nephrectomy to remove the tumor and preserve as much renal function as possible.

* Preoperative imaging studies (ultrasound, CT scan) showing the location and size of the affected renal tissue.* Operative report detailing the surgical technique, tissue removed, and assessment of the remaining kidney.* Pathology report confirming the diagnosis and extent of resection.* Postoperative imaging (optional, depending on payer requirements) to assess for complications.* Clinical notes documenting the patient's clinical presentation, medical history, and response to treatment.
