Clinical & Coding Specifications
Clinical Context
A typical patient is a 62-year-old adult presenting with a renal mass identified incidentally on abdominal imaging or with hematuria and flank pain. After cross-sectional imaging (CT or MRI) and preoperative assessment, the patient is scheduled for a nephrectomy — either radical nephrectomy for suspected or confirmed renal cell carcinoma or partial nephrectomy for a small, localized tumor. The clinical workflow includes preoperative evaluation (history, labs, anesthesia assessment), imaging review, informed consent, perioperative antibiotics, general anesthesia with possible regional block, intraoperative removal of the kidney or portion of the kidney with hemostasis, possible lymph node sampling, placement of drains if needed, and postoperative monitoring in PACU with discharge planning or inpatient admission for postoperative care and pathology follow-up.
