CPT code 44365 represents an upper small intestinal endoscopy that advances past the second portion of the duodenum but stops short of the ileum, with removal of one or more lesions using hot biopsy forceps or bipolar cautery. This code captures combined diagnostic visualization and therapeutic polypectomy/lesion excision in the proximal small bowel. Nationally, the code matters for procedural classification, facility and professional billing, and appropriate coding of combined diagnostic and destructive techniques during enteroscopy procedures.

Key payers addressed in analyses typically include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, guidance on typical sites of service, and where to expect claim activity for combined diagnostic and therapeutic enteroscopy. The publication also outlines common modifiers and coding relationships where available and highlights benchmarking and policy considerations relevant to payer coverage and claim adjudication. This summary serves clinicians, coding professionals, and reimbursement analysts seeking a clear description of CPT code 44365, its clinical application, and the payer landscape for national-level billing and policy alignment.
