Check a contract rate as a % of Medicare · 76940 nationwide

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 76940 covers

This service uses ultrasound to guide the ablation target and monitor treatment of parenchymal tissue. It may accompany image-guided treatment of solid-organ lesions, including liver or kidney lesions. The procedural physician or an imaging specialist may perform the ultrasound portion in a hospital or outpatient setting. The ablation treatment itself is reported separately with the applicable procedure code.

Medicare assigns this CPT code carrier-priced status: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. Medicare treats it as a diagnostic test with professional and technical components. Modifier 26 identifies the interpretation; modifier TC identifies the equipment and staff portion. Reporting the code without either modifier represents the global service. The contractor also sets the global period. The code is not dose-based; documentation should support ultrasound guidance and monitoring during tissue ablation.
