Summary & Overview
CPT 50200: Percutaneous Renal Aspiration for Diagnostic Biopsy
CPT code 50200 identifies a percutaneous renal aspiration procedure in which a physician inserts a collection needle into the kidney to obtain a sample for diagnostic biopsy. This code captures a focused, image-guided or bedside diagnostic intervention used to obtain tissue or fluid for pathological analysis and can be billed when the primary purpose is diagnostic sampling rather than therapeutic intervention. Nationally, renal biopsy and aspiration procedures are clinically important for diagnosis of intrinsic kidney diseases, transplant surveillance, and evaluation of unexplained renal masses or hematuria.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical indications and typical sites of service, common billing and coding considerations, payer coverage patterns, and where available, reimbursement benchmarks and claim-processing notes. The publication also summarizes relevant policy updates that affect preauthorization, site-of-service determinations, and documentation requirements.
This resource is intended to help coding and billing staff, practice managers, and policy analysts understand the clinical context of CPT code 50200, typical billing scenarios, and payer-relevant issues that influence claim adjudication and documentation expectations.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 55-year-old adult with a solitary renal mass identified on abdominal imaging (CT or ultrasound) or with unexplained hematuria and a suspicious focal lesion. The patient is evaluated by a urologist or interventional radiologist. After review of risks, benefits, and coagulation status, the patient is scheduled for a percutaneous kidney biopsy. On the day of the procedure the patient is placed prone or in a modified lateral decubitus position, local anesthesia is administered, and real-time imaging guidance (ultrasound or CT) is used to direct a percutaneous collection needle into the renal cortex to obtain tissue cores or aspirate for histopathology and microbiology when indicated. Post-procedure monitoring includes vital signs, observation for hematuria or flank pain, and follow-up imaging only when clinically indicated. The procedure may occur in an outpatient radiology suite, ambulatory surgery center, or inpatient setting depending on clinical status and comorbidities.
