Billing tips

Always verify whether facility or non-facility setting applies, though for 93312 both rates are identical at $225.46, this matters for many bundled services
Impact: Ensures correct claim submission and prevents processing delays
Document complete study including all required cardiac views and structures, or clearly specify why certain views were unobtainable; incomplete studies may require modifier 52 and reduced payment
Impact: Incomplete documentation can result in 25-50% payment reduction or denial
Bill 93312 separately from intraoperative monitoring codes (93318) - these are distinct services with different documentation requirements
Impact: Prevents bundling denials and preserves full $225.46 reimbursement for diagnostic TEE
When TEE is performed as part of cardioversion or ablation, ensure medical necessity is documented beyond the procedure itself; link to specific diagnostic indication
Impact: Lack of distinct medical necessity documentation results in 30-40% denial rate for same-day TEE
Submit claims within Medicare's timely filing limit (1 year from date of service) and verify secondary insurance timely filing requirements which may be shorter
Impact: Late submissions result in complete denial of $225.46 with no appeal rights
Code separately for conscious sedation when applicable and not included in facility fee; verify payer-specific policies as Medicare bundled moderate sedation into many procedures effective 2017
Impact: May capture additional $50-100 when sedation is separately billable and properly documented

Frequently asked questions

What is the Medicare reimbursement rate for CPT code 93312 in 2025?

The 2025 Medicare national average reimbursement rate for CPT 93312 is $225.46 for both facility and non-facility settings. This rate is based on a total RVU of 6.97 multiplied by the 2025 conversion factor of 32.3465. Actual payment may vary by geographic locality based on the Geographic Practice Cost Index (GPCI) adjustments.

Can CPT 93312 be billed with a cardioversion or ablation procedure on the same day?

Yes, but it requires careful documentation and may require modifier 59 to indicate a distinct procedural service. You must document that the TEE served a separate diagnostic purpose beyond routine procedural monitoring, such as pre-procedure thrombus exclusion or assessment of structural abnormalities that would alter the treatment approach. Without clear medical necessity for a separate diagnostic indication, payers may bundle the service.

What is the difference between CPT 93312 and 93318?

CPT 93312 is for diagnostic transesophageal echocardiography performed as a standalone procedure, while CPT 93318 is specifically for intraoperative or perioperative TEE monitoring during cardiac or thoracic surgery. Code 93318 includes real-time monitoring throughout the procedure, while 93312 is a diagnostic study performed at a specific point in time with complete documentation and interpretation.

Do I need modifier 26 or TC when billing CPT 93312?

Use modifier 26 if you are billing only for the professional component (physician interpretation and report) and did not provide the equipment or technical staff. Use modifier TC if billing only for the technical component (equipment, supplies, staff) without physician interpretation. Bill 93312 without modifiers only when providing both components. In hospital settings, the facility typically bills TC and the physician bills with modifier 26.

What are the RVU values for CPT 93312 in 2025?

The 2025 RVU values for CPT 93312 are: Work RVU 2.3, Practice Expense (PE) RVU 4.57 for both facility and non-facility settings, and Malpractice (MP) RVU 0.1, totaling 6.97 RVUs. These values reflect the physician work, practice overhead, and malpractice insurance costs associated with performing and interpreting a transesophageal echocardiogram.

How often can CPT 93312 be billed for the same patient?

There is no specific frequency limitation for CPT 93312, but each study must have distinct medical necessity documentation. Payers scrutinize repeat TEEs performed within short intervals and may deny as not medically necessary without documentation of interval clinical change, new symptoms, or specific need for reassessment. Serial TEEs for endocarditis treatment monitoring or post-surgical evaluation may be appropriate with proper justification.

What documentation is required to prevent denials for CPT 93312?

Required documentation includes: specific indication with clinical question, informed consent, systematic evaluation of all cardiac structures, quantitative measurements, description of abnormalities with severity grading, interpretation with clinical correlation, physician signature and credentials, and documentation explaining why TEE was chosen over transthoracic echo. Incomplete studies must document reasons certain views were unobtainable and may require modifier 52.
