HCPCS Level II code C9734 denotes MR-guided focused ultrasound ablation or therapeutic intervention for indications other than uterine leiomyomata. The code captures a specialized, image-guided, noninvasive ablative technique that has grown in clinical relevance as MR-guided focused ultrasound is applied to a range of benign and malignant targets. Nationally, the code matters because it identifies high-technology, capital-intensive procedures that require MR-compatible treatment suites, multidisciplinary teams, and specific documentation to support medical necessity and appropriate billing.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will gain a concise view of what C9734 represents clinically and operationally, plus a roadmap to typical coverage considerations and billing contexts to expect across major commercial payers and Medicare. The publication outlines reimbursement benchmarks where available, policy and coverage themes relevant to MR-guided focused ultrasound, and the typical clinical scenarios and service settings where the code is used. Additional sections provide common modifiers, related codes, and guidance on documentation and claim submission practices.

This summary is written for a national audience and provides the essential clinical and billing context for healthcare administrators, coders, and clinicians working with MR-guided focused ultrasound services.
