Billing tips

Bill 76998 only when ultrasound guidance is performed in addition to a primary surgical procedure, not when it is already included in the surgical code descriptor
Impact: Prevents denials for services already bundled; reviewing NCCI edits prevents 30-40% of common rejections for this code
Ensure separate documentation of the ultrasound guidance distinct from the operative note, including images saved to the medical record or detailed description of imaging findings
Impact: Absence of documentation is the leading cause of denials; proper documentation protects the full $44.96 reimbursement
Verify that 76998 is not bundled with the primary procedure code using current NCCI edits before billing; many payers have specific bundling rules for intraoperative imaging
Impact: Pre-verification prevents claim rejections and reduces accounts receivable days by 15-20 days on average
Code 76998 is time-based only in that it represents guidance during the intraoperative period; do not bill multiple units unless multiple distinct operative sessions occur
Impact: Billing multiple units inappropriately can trigger audits; single unit billing at $44.96 is standard regardless of imaging duration
When both ultrasound and another imaging modality (e.g., fluoroscopy) are used intraoperatively, append modifier 59 or XU to the less commonly bundled code
Impact: Proper modifier use can capture additional $40-150 in imaging guidance fees that would otherwise be denied
Confirm the performing physician is the same as the surgeon; if a radiologist provides the guidance, separate billing rules and documentation requirements apply

Frequently asked questions

What is CPT code 76998 used for?

CPT code 76998 is used to bill for ultrasound imaging guidance performed during a surgical procedure in the operating room. It represents real-time ultrasound imaging that helps the surgeon visualize anatomical structures, guide instrument placement, or confirm lesion removal while the surgery is in progress.

How much does Medicare pay for CPT 76998 in 2025?

Medicare pays $44.96 for CPT code 76998 in 2025 under the national average rate. Both the facility and non-facility rates are identical at $44.96, with a total RVU of 1.39 (work RVU 0.91, PE RVU 0.32, MP RVU 0.16).

Can CPT 76998 be billed alone or does it require a primary procedure?

CPT 76998 cannot be billed alone; it is an add-on service that must be reported with a primary surgical procedure. The ultrasound guidance is performed during another operative procedure and is billed in addition to the primary surgery code.

What documentation is required to bill CPT 76998?

Documentation must include medical necessity for intraoperative imaging, proof that ultrasound was performed in real-time during surgery, description of structures visualized, how the imaging guided the procedure, and either saved images or detailed written findings. The operative note must clearly distinguish the ultrasound service from the primary surgical procedure.

Is CPT 76998 bundled with other surgical codes?

Yes, CPT 76998 is frequently bundled with certain surgical procedures under NCCI edits. Billers must check current NCCI edits before submitting claims. When bundling exists, modifier 59 or XU may be required to indicate a distinct service, but only when documentation supports separate reporting.

Who can bill CPT 76998 - the surgeon or radiologist?

Either the operating surgeon or a radiologist can bill CPT 76998, depending on who performs and interprets the intraoperative ultrasound. The physician billing must document their personal performance of the imaging and interpretation. If performed by the surgeon, it is typically included in their surgical billing.

What are common reasons for CPT 76998 claim denials?

Common denials include bundling with the primary procedure without appropriate modifiers, insufficient documentation of separate ultrasound service, lack of medical necessity justification, missing ultrasound images or detailed findings description, and billing with procedures that inherently include imaging guidance in their code descriptors.
