Billing tips

Never bill 93307 with Doppler codes (93320-93325) for the same session - if Doppler is performed, use comprehensive codes 93303-93304 instead
Impact: Prevents automatic denials and potential fraud flags; proper code selection increases clean claim rate by 35-40%
Document all required cardiac views (parasternal long/short axis, apical 4/2/3 chamber, subcostal) to support 'complete' designation
Impact: Incomplete documentation may result in downcoding to limited study (93308) with $29-40 lower reimbursement
Bill professional (26) and technical (TC) components separately only when performed in different locations or by different entities
Impact: Improper splitting can trigger recoupment; correct component billing ensures full $131 payment is properly distributed
Verify medical necessity with appropriate ICD-10 codes (I50.x for heart failure, I48.x for atrial fibrillation, R94.31 for abnormal ECG) before performing study
Impact: Pre-authorization compliance reduces denial rate by 60%; lack of medical necessity is #1 denial reason for echocardiography
When billing same-day as E/M service, ensure separate documentation justifies medical necessity of immediate echocardiogram versus scheduled outpatient study
Impact: Prevents bundling denials; proper documentation with modifier 25 on E/M maintains full reimbursement for both services
For Medicare patients, confirm study meets appropriate use criteria (AUC) and submit CEHRT G-codes when required
Impact: AUC consultation requirement began 2020; non-compliance may trigger payment holds or denials starting in enforcement phases

Frequently asked questions

What is the difference between CPT 93307 and 93306?

CPT 93307 is a complete transthoracic echo without Doppler, while 93306 is the complete study WITH Doppler. Code 93306 has been deleted and replaced by 93303-93304 in current CPT. If any Doppler (color flow, spectral, or continuous wave) is performed, you cannot bill 93307 - you must use the comprehensive codes instead.

How much does Medicare pay for CPT 93307 in 2025?

Medicare pays $131 for CPT 93307 in 2025 based on the national average rate. This represents 4.05 total RVUs (0.92 work RVU, 3.08 practice expense RVU, 0.05 malpractice RVU) multiplied by the 2025 conversion factor of 32.3465. Actual payment may vary by geographic locality.

Can you bill 93307 and 93320 together on the same date?

No, you cannot bill 93307 (echo without Doppler) and 93320 (Doppler add-on) together. If Doppler is performed during the same session, you must bill a comprehensive echocardiography code (93303 or 93304) instead. Billing both will result in denial for unbundling or incorrect coding.

What diagnosis codes are typically used with CPT 93307?

Common ICD-10 codes include I50.9 (heart failure), I48.91 (atrial fibrillation), I51.9 (heart disease unspecified), R94.31 (abnormal ECG), I25.10 (coronary artery disease), I11.9 (hypertensive heart disease), and Z95.1 (cardiac device status). The diagnosis must support medical necessity for the echocardiogram.

When should I use modifier 26 vs TC with CPT 93307?

Use modifier 26 when billing only the physician interpretation (professional component), typically when the hospital or imaging center owns the equipment. Use modifier TC when billing only the technical component (equipment, staff, supplies). In physician offices owning their equipment, bill 93307 without modifiers for the complete global service receiving the full $131.

Is CPT 93307 a complete or limited echocardiogram?

CPT 93307 is a complete transthoracic echocardiogram without Doppler. It requires evaluation of all cardiac structures with comprehensive 2D and M-mode imaging. CPT 93308 is the limited/follow-up echo code. Documentation must support that all required anatomical views and structures were evaluated to bill 93307.

How many times can CPT 93307 be billed per year for the same patient?

There is no specific Medicare limit on frequency, but medical necessity must be documented for each study. Commercial payers may have coverage policies limiting frequency (e.g., one routine echo per year). Repeat studies require documentation of clinical change, new symptoms, post-intervention monitoring, or acute condition assessment to justify medical necessity.
