CPT code 19288 denotes an add-on magnetic resonance image (MRI) guidance procedure used to place an additional localization device for breast lesions — for example, a clip, metallic pellet, wire/needle, or radioactive seed — when placed during the same session as an initial device. As an add-on code, it is reported in conjunction with a primary breast localization or image-guided procedure and is relevant for facilities and radiology or breast surgery providers who perform image-guided interventions.

This publication addresses national reimbursement and operational context across major payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of how the service is defined clinically, typical sites of service, and what to expect in claims submissions for an add-on MRI-guided localization. The report summarizes payer coverage trends, common billing modifiers observed in practice, and considerations for coding when multiple localization devices are placed in one session.

The briefing provides actionable benchmarking and policy context: it explains clinical indications for MRI-guided localization, how the add-on nature of 19288 affects reporting, typical settings where the procedure is performed, and areas where payer policies or documentation requirements commonly vary. Data not available in the input is noted where applicable.
