Preoperative Diagnosis:

Right [left] renal mass — [clear cell / papillary / chromophobe] renal cell carcinoma, clinical stage [T1b–T3], not amenable to partial nephrectomy

Postoperative Diagnosis:

Same

Procedure Performed:

Right [left] laparoscopic [/ robotic] radical nephrectomy [with adrenalectomy]

Attending Surgeon:

[Attending name], MD/DO

First Assistant:

[Resident/PA name]

Anesthesia:

General endotracheal

Indications:

The patient is a [age]-year-old [male/female] with a [X]-cm right [left] renal mass on CT, clinically staged as [T2/T3] RCC [/ indeterminate mass requiring pathologic diagnosis]. The mass was not amenable to partial nephrectomy given [central location / tumor thrombus / size]. Contralateral kidney function was adequate. The risks, benefits, and alternatives were discussed and informed consent was obtained.

Findings:

The kidney was [mobile / with minimal perinephric fat stranding]. The renal hilum was [defined / with enlarged hilar lymph nodes]. The mass was [X] cm at the [upper / lower / mid] pole. The adrenal gland was [adherent / separate — spared / resected given [ipsilateral adrenal mass / tumor involvement]]. The ureter was divided at [the pelvic brim / iliac vessels]. The renal vein and artery were ligated.

Description of Procedure:

The patient was positioned in the lateral decubitus position with the operative side up, flexed at the waist. A [12-mm] port was placed at the umbilicus via [Veress needle / optical trocar / Hasson open technique]. Additional [5-mm] ports were placed in standard configuration. The kidney was mobilized in the retroperitoneal fat.

[RIGHT SIDE:]
The colon was reflected medially by incising the white line of Toldt. The duodenum was mobilized (Kocher). The renal vein was identified and dissected. The renal artery was identified posterior to the vein and [doubly clipped and divided / stapled with a [30-mm] vascular load]. The renal vein was [clipped / stapled]. The ureter was clipped and divided distally.

[LEFT SIDE:]
The descending colon was reflected medially. The gonadal vein was clipped and divided. The adrenal vein was [identified and preserved / clipped and divided for adrenalectomy]. The renal artery was clipped posterior to the vein. The renal vein was clipped and divided.

The kidney was [dissected from Gerota's fascia / kept within Gerota's fascia]. The adrenal gland was [spared / removed en bloc]. The specimen was placed in a 15-mm Endocatch bag and extracted through a [Pfannenstiel / extension of umbilical] incision. The fascia was closed with [0-Vicryl]. Skin was closed with [4-0 Monocryl].

Complications:

None

Specimens:

Right [left] kidney — sent to pathology. [Adrenal gland — sent separately.]

Estimated Blood Loss:

[X] mL

Drains:

None / [Jackson-Pratt drain in renal fossa]

Disposition:

The patient was taken to the PACU in stable condition. Ambulation was initiated on postoperative day 1. Diet was advanced as tolerated.

Robotic Partial Nephrectomy

For a [T1a/T1b] tumor amenable to nephron-sparing, robotic partial nephrectomy was performed. After hilar vessel identification, the renal artery was controlled with a bulldog clamp — warm ischemia time was [X] minutes. The tumor was excised with [5–10]-mm margins using cold scissors. The pelvicalyceal system was [entered / not entered — repaired with 3-0 Vicryl]. The renorrhaphy was performed in two layers with [2-0 Vicryl] horizontal mattress sutures bolstered with Surgicel and [Hem-o-lok clips for sliding clip technique]. The bulldog clamp was removed and hemostasis confirmed. Warm ischemia time <25 minutes is the target. Document ischemia time in the note.

Charting Tips
  • Document adrenal management and rationale. The ipsilateral adrenal gland is typically spared unless there is a separate adrenal mass, direct tumor invasion, or an upper pole tumor abutting the adrenal. Document whether the adrenal was resected and the reason.
  • Document hilar vessel control sequence. The renal artery must be controlled before the vein to prevent venous engorgement and bleeding. Document 'renal artery was identified and ligated first, followed by the renal vein.'
  • Document specimen extraction method. For oncologic cases, the specimen must be extracted intact in an impermeable retrieval bag without morcellation. Document the bag used and that the specimen was extracted intact.
Billing Tips
  • Laparoscopic radical nephrectomy: 50545 (24.43 wRVU); laparoscopic simple nephrectomy: 50546 (21.32 wRVU). Radical vs simple is determined by perifascial vs perinephric dissection plane, not tumor size.
  • Open simple nephrectomy: 50220 (18.21 wRVU); open complex (prior surgery, adhesions, large tumor): 50225 (21.33 wRVU). Use 50225 for documented increased complexity; modifier -22 alone is insufficient.
  • Partial nephrectomy: 50240 open (23.60 wRVU) vs 50543 laparoscopic (26.72 wRVU). Laparoscopic partial is higher-weighted due to technical complexity.
  • Adrenalectomy performed en bloc is separately billable (60540/60650) with modifier -51; document that ipsilateral adrenalectomy was separately performed and indicate its indication.
  • Lymph node dissection (38780 retroperitoneal) performed for staging is separately billable when performed as a distinct dissection. Document templates and stations.
  • Global period is 90 days. Post-op drain management and routine wound care are bundled. Delayed hemorrhage or urinoma requiring intervention uses modifier -78.
  • Robot-assisted procedures use the same CPT codes as laparoscopic; append no robotic modifier. Document robotic approach in the operative note for facility billing purposes.
