CPT code 50045 denotes a surgical intervention to relieve urinary outflow obstruction that prevents urine from draining into the kidneys. Such obstructions commonly arise from malignancies (for example ovarian or colon cancer), nephrolithiasis (kidney stones), or severe infections like pyonephrosis. The code is relevant nationally because urinary obstruction can lead to renal damage, sepsis, and significant downstream costs if not managed promptly.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context for when the procedure is used, typical settings of care, and the payer landscape that affects coverage and claims processing. The publication provides benchmarks where available, identifies common billing modifiers associated with this type of surgical service, and summarizes implications for utilization and coding practice.

The content is organized to give clinicians, coders, and policy professionals a concise reference: what the code represents, why it matters for patient outcomes and system costs, how payers commonly approach coverage, and where to look for further coding or policy updates. Data not available in the input is noted where applicable.
