Echo transesophageal
CPT 93316 covers the physician's interpretation and written report of a transesophageal echocardiogram (TEE), where an ultrasound probe inserted through the esophagus creates detailed images of the heart. This is the professional component only, representing the doctor's expertise in reading and analyzing the images.

Billing tips
Always bill 93316 as an add-on to the primary TEE procedure code (93312, 93313, 93314, or 93315) - it cannot be billed alone
Impact: Failure to bill with primary code results in 100% denial; proper pairing ensures $24.26 payment
Verify the primary TEE code includes probe placement and image acquisition - 93316 is only for the additional interpretation component
Impact: Incorrect primary code selection leads to bundling denials and loss of separate reimbursement
Document the separate interpretation and report in the medical record with time, date, and distinct physician signature if different from the performing physician
Impact: Missing documentation is the #1 audit trigger; proper documentation protects $24.26 payment in post-payment reviews
Bill 93316 only once per encounter regardless of how many times the images are reviewed during the same session
Impact: Multiple units on same date will be denied; proper unit billing prevents overpayment recovery
Ensure the written interpretation includes all required elements: indication, technical quality, complete anatomic findings, measurements, and clinical correlation
Impact: Incomplete reports are frequently downcoded or denied on review; comprehensive documentation secures full payment
For intraoperative TEE, verify payer-specific policies as some require different coding or consider it bundled into surgical fees
Impact: Commercial payers may bundle intraoperative TEE interpretation into global surgical payment; verify policies to avoid 100% denial
Common denials
Billed without a primary TEE procedure code (add-on code requirement not met)
How to appeal: Submit appeal with operative/procedure report showing primary TEE service was performed and documented; provide CPT coding guidelines showing 93316 is an add-on code requiring base procedure; resubmit claim with correct primary code
Bundled or considered inclusive of the primary TEE service by the payer
How to appeal: Reference CPT guidelines that specifically designate 93316 as separately reportable; provide Medicare's NCCI edits showing no bundling; cite payer's own fee schedule listing 93316 as a payable service; include documentation showing distinct professional interpretation
Insufficient or missing interpretation report documentation
How to appeal: Submit complete signed and dated interpretation report showing all required elements; provide attestation from performing physician; reference Medicare documentation requirements for diagnostic tests requiring physician interpretation
Duplicate billing - multiple units or billing by multiple physicians without appropriate modifiers
How to appeal: Provide documentation showing medical necessity for repeat study (use modifier 76) or separate interpretations by different physicians (use modifier 77); include clinical notes explaining why second interpretation was required; demonstrate distinct services
Frequently asked questions
What is CPT code 93316 used for?
CPT 93316 is used to report the physician's professional interpretation and written report of a transesophageal echocardiogram (TEE). It is an add-on code that must be billed with a primary TEE procedure code and represents only the cognitive work of analyzing images and documenting findings, not the probe placement or image acquisition.
How much does Medicare pay for CPT 93316 in 2025?
Medicare pays $24.26 for CPT 93316 in 2025 (national average for both facility and non-facility settings). This is based on 0.75 total RVUs (0.6 work RVU + 0.11 PE RVU + 0.04 MP RVU) multiplied by the 2025 conversion factor of 32.3465.
Can CPT 93316 be billed alone?
No, CPT 93316 cannot be billed alone. It is designated as an add-on code (indicated by the '+' symbol in CPT) and must be reported with a primary transesophageal echocardiography procedure code such as 93312, 93313, 93314, or 93315. Billing 93316 without a qualifying primary code will result in denial.
What is the difference between CPT 93316 and 93315?
CPT 93315 is a complete transesophageal echocardiography procedure code that includes probe placement, image acquisition, and interpretation. CPT 93316 is an add-on code used for additional interpretation work beyond what is included in the base TEE codes. They serve different purposes and 93316 would be used in conjunction with, not instead of, primary TEE codes.
Do I need modifier 26 for CPT 93316?
Generally no. CPT 93316 is inherently a professional component code representing only physician interpretation work. However, some payers may request modifier 26 for clarity or have specific billing requirements, so verify with individual payer policies. The code descriptor itself indicates it is for professional services only.
How many times can I bill 93316 per day?
CPT 93316 should typically be billed only once per encounter/date of service, regardless of how many times the images are reviewed during that session. If a repeat TEE study with separate interpretation is medically necessary on the same day, use modifier 76 (same physician) or 77 (different physician) with strong documentation justifying the medical necessity.
What documentation is required to bill CPT 93316?
Required documentation includes a separate signed and dated interpretation report containing: indication for TEE, image quality statement, comprehensive cardiac structure descriptions, quantitative measurements, comparison to prior studies, clinical impression, and physician signature. The interpretation must be documented as distinct from the technical performance of the TEE procedure.
