CPT code 93312: Transesophageal echo billing and 2026 rates

Key takeaways

CPT code 93312 covers a complete diagnostic transesophageal echocardiogram, including probe placement, real-time 2D acquisition, and a written interpretation.

Continuous intraoperative monitoring with no separate formal report belongs under CPT 93318, not under 93312.

One physician cannot bill 93312 alongside 93313 or 93314, because NCCI edits bundle the component codes together.

CY2026 Medicare pays roughly $105 for the professional component, $135 for the technical component, and $241 for the global service.

Practice management software like Pabau pre-fills 93312 claim details from the client record and submits them through the Claim.MD clearinghouse.

CPT code 93312 reports a complete diagnostic transesophageal echocardiogram, or TEE, performed and interpreted by one physician. One fact decides most of these claims. The study needs a formal written report, and without one the service usually belongs under 93318 instead.

That single line trips up cardiology and anesthesia billers constantly, because intraoperative TEE often involves two physicians and two separate codes. Pick the wrong one and the rework takes weeks.

Below you will find the AMA descriptor, the split-service rules, and the modifiers that apply. The CY2026 Medicare rates and the documentation an auditor asks for come after that.

What 93312 covers, component by component

CPT code 93312 covers a complete, discrete transesophageal echocardiography study performed by one physician.

The American Medical Association’s CPT codebook describes it as real-time transesophageal echocardiography with 2D image documentation, with or without M-mode recording. It then names three inclusions.

Those are probe placement, image acquisition, and interpretation with a written report.

All three components sit inside one code, so a single physician has to perform all of them. Surgical settings often split the work. An anesthesiologist places the probe while a cardiologist reads the images, and the component codes 93313 and 93314 apply instead.

TEE sees what a chest-wall probe cannot

TEE differs from transthoracic echocardiography, code 93306, in one respect. The ultrasound probe travels down the esophagus instead of resting on the chest wall.

That position removes lung and rib interference, so the physician gets a clearer view of posterior structures. The left atrium, the aortic valve, and the descending aorta all read better this way.

Three settings account for most 93312 studies:

• Discrete diagnostic assessment during cardiac surgery: the cardiologist performs a complete study, such as a pre-bypass baseline or a post-bypass check on a valve repair. Each study gets its own written report. Continuous surveillance across the whole case is reported separately, under CPT 93318.
• Non-cardiac surgery in high-risk patients: used when the team expects hemodynamic instability and the surgical position makes transthoracic access impractical.
• Critical care: occasionally used in ICU patients when transthoracic image quality is too poor to guide a management decision.

So the formal written report is what separates 93312 from continuous monitoring under 93318. Code selection follows the purpose of the service, not the technical steps at the bedside.

Medical necessity must name the patient, not the surgery

Medical necessity for 93312 lives in the record, and it has to be specific. Coverage runs through each Medicare Administrative Contractor’s local coverage determination for echocardiography, alongside CMS coverage article A56505.

The indications below appear most often in MAC policies. Check your own jurisdiction before you submit.

• A discrete intraoperative diagnostic TEE during cardiac or major vascular surgery, such as a pre-bypass or post-bypass assessment with a formal report
• A discrete diagnostic TEE during non-cardiac surgery, when a specific hemodynamic or structural question arises and needs a formal interpretation
• Evaluation of valvular function, including regurgitation severity and repair adequacy, during cardiac surgical procedures
• Assessment of left and right ventricular function when transthoracic imaging is unavailable or inadequate
• Detection of intracardiac thrombus, air, or foreign material during a surgical procedure
• Evaluation of aortic pathology such as dissection or aneurysm, when intraoperative surveillance is required
• A diagnostic study performed around a structural heart procedure, where the TEE is not the imaging guidance for the intervention itself

When TEE guides a transcatheter structural intervention, such as TAVR or mitral repair, the guidance service is 93355 rather than 93312. A separate diagnostic study can still stand on its own alongside it.

Documentation should state why this patient needed this study on this day. A generic indication such as “cardiac surgery” is a standing audit finding.

Modifiers decide who gets paid for what

Modifier choice is where most 93312 billing errors begin. The split-service pattern is routine in teaching hospitals and large cardiac centers. An anesthesiologist places the probe, a cardiologist reads the images, and the modifiers have to match who did what.

The split-service rule: when two physicians each perform part of what would be 93312, neither one bills 93312. The probe-placing physician bills 93313, and the interpreting physician bills 93314. A single physician also cannot bill 93312 with 93313 or 93314, because NCCI bundles them.

The written report carries the whole claim

The most common reason a 93312 claim fails on audit is a missing or thin written report. The claim itself is only a summary. Behind it, the medical record has to carry every element CMS and the MAC policies ask for.

• Clinical indication: a patient-specific reason for the study, not a generic procedure description
• Probe placement note: confirmation that the performing physician placed the esophageal probe and that the patient tolerated insertion
• Image acquisition note: a record of the real-time 2D acquisition, including the phase of the case, for example pre-bypass or post-bypass
• Written interpretation: a distinct report giving ventricular function, valvular status, any abnormality found, and a clinical impression
• Ordering physician: who ordered the study and the clinical context behind the request
• Physician identity: under split-service billing, each record has to show which component that physician performed

Template reports that repeat the same boilerplate without patient-specific findings draw attention fast. Each report has to reflect what the physician saw in that patient, on that date.

What Medicare pays for 93312 in 2026

Payment for 93312 depends on where the service happens and on which components you bill. A hospital or ambulatory surgery center splits it, so the physician bills the professional component and the facility is paid separately. In an office, one global charge covers the work and the overhead.

Rates shift every year and by locality, so verify before you submit. The CMS Physician Fee Schedule Look-Up Tool returns the current figure for your carrier area.

How the 2026 RVUs add up

Medicare builds the payment from three relative value unit components, then multiplies the total by the annual conversion factor. For CY2026 that factor is $33.4009, rising to $33.5675 for clinicians who qualify as advanced APM participants.

The practice expense figure above is the balance of the global total after work and malpractice. Geographic practice cost index adjustments then move the dollar amount by locality, so treat these as national values.

Professional, technical and global rates side by side

Use place of service 21 or 22 on a hospital claim and 11 on an office claim. The professional component is the usual physician charge, because most TEE studies happen in a facility that bills the technical side itself.

Five errors that get 93312 denied

Billing teams see the same five failures over and over. Each one is preventable at the point of claim creation. Fixing it there costs far less than reworking a denial three weeks later.

• No written report on file. This is the top denial trigger. The interpretation has to exist as a distinct, patient-specific document before the claim goes out.
• 93312 billed with 93313 or 93314 by the same physician. NCCI bundles them. A physician bills the complete code or the component codes, never both.
• A modifier used to paper over a split service. When two physicians share the work, each bills their own component code. Attaching a modifier to 93312 does not clear the bundle.
• A place-of-service code that contradicts the operative note. Billing the global rate for a hospital procedure overstates the claim and reads as a compliance risk.
• Add-on codes appended without support. 93320 and 93325 may be reported with 93312 when Doppler is performed. Check current NCCI status, and document the medical necessity of each.

Four things have to line up before a 93312 claim counts as a clean claim submission. The right code and the right modifier come first. You also need a place of service that matches the note, and a written report already on file.

Sorting rejections by denial codes tells you which of the four broke. Track those patterns quarterly. You will soon see whether the problem sits with one surgeon, one payer, or one documentation habit.

Choosing the right code in the TEE family

The codes sitting around 93312 are close neighbors, and picking the wrong one costs more than most coding slips. Bundling rules between them are strict and audit detection is high.

The American Society of Echocardiography publishes detailed guidance on the family. Work down the ladder below and stop at the first row that matches your service.

One note on 93318, because it is the code coders reach for last. When an anesthesiologist runs TEE purely for hemodynamic surveillance and writes no structured report, 93318 is correct. Billing 93312 for that service claims a report that does not exist, which is exactly what an auditor looks for.

93312 and 93306 answer different clinical questions

Coders mix up 93312 and 93306 more often than any other pair in this family. The approach differs, and so does the billing profile. Reading both correctly protects the practice when one patient record shows a TTE and a TEE within days.

Run this check before you submit

Before a 93312 claim leaves the practice, walk the same six questions every time. Each one maps to a denial pattern from the sections above.

1. Did one physician perform placement, acquisition and interpretation? If two shared the work, bill 93313 and 93314.
2. Is the written report signed and filed, with findings and a clinical impression?
3. Does the indication name this patient’s clinical question, rather than the surgery?
4. Was this a diagnostic study, or guidance for a transcatheter intervention? Guidance is 93355.
5. Does the place-of-service code match the operative note, and does the modifier match it too?
6. Are 93320, 93325 or 93319 supported by work the report describes?

Six questions take about a minute. A denied 93312 claim takes three weeks and a rebill.

How claims management software supports 93312 billing

Cardiology teams that bill high volumes of intraoperative TEE run into the same friction. The documentation sits in the anesthesia record, the coding sits with a biller, and the two rarely meet before the claim goes out. Most 93312 errors get caught at claim creation or not at all.

Practice management software like Pabau closes that distance. Pabau’s claims management software pre-fills the claim form from the client record. The CPT code attached to the service lands on the charge line, and the recorded diagnoses seed the ICD-10 fields.

Built-in CPT and ICD-10 lookup libraries sit behind a search icon, refreshed with each official release. Before the send button unlocks, the system checks that claim-required fields are complete.

On the US pipeline, claims go out through Claim.MD, with real-time eligibility checks, remittance posting and claim-status tracking.

It will not choose your modifier for 93312, and it will not read the operative note for you. What it does is stop a claim leaving with a field missing. It also gives the billing team one place to watch what came back. A pattern of 93312 denials then shows up in a week rather than a quarter.

Conclusion

93312 rewards a practice that has one clear protocol, and punishes one that improvises. The deciding facts sit outside the coder’s reach, in the operative record and in who did what in the room.

So settle three questions in advance and the rest follows. Decide who performs each component, who writes the report, and how quickly that report reaches the chart. Apply the same answers to every TEE case, and the denial rate falls without anyone chasing individual claims.
