CPT code 49186 designates an open surgical procedure to excise or destroy one or more abdominal tumors or cysts with a combined maximum length of 5 cm or less. This code captures a specific, limited-size lesion burden and signals an open abdominal operative approach rather than laparoscopic or percutaneous techniques. Nationally, accurate use of this code affects surgical case classification, facility billing, and clinical quality reporting for small intra-abdominal mass management.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a concise overview of expected coding scope, typical sites of service (operating room, ambulatory surgery center, or hospital inpatient setting), and the clinical context in which an open approach for small abdominal lesions is reported.

Readers will learn: the clinical definition and limits that distinguish this code from other abdominal tumor excision codes; payer coverage landscape and common billing modifiers used with surgical CPT codes (listed separately); and operational considerations relevant to facility and professional service lines. Data not available in the input for payer-specific reimbursement rates, ICD-10 pairings, taxonomies, and related codes are noted as unavailable where applicable.
