Billing tips
Ensure documentation includes all required elements for 'complete' study: assessment of LV and RV function, all four valves, pericardium, great vessels, and comprehensive Doppler evaluation
Impact: Incomplete documentation forces downcoding to 93307 (without Doppler) or 93308 (follow-up/limited), reducing reimbursement by $60-$90 per study
Bill professional (26) and technical (TC) components separately when services are split between physician and facility to maximize appropriate reimbursement
Impact: Prevents revenue loss when split billing is appropriate; global billing in split scenarios results in underpayment to one party
Verify patient has not had another complete TTE within 30 days unless acute clinical change documented, as many payers consider repeat studies within this window not medically necessary
Impact: Prevents denials for frequency limitations; when repeat study is necessary, document specific clinical indication such as post-intervention assessment or acute decompensation
Do not bundle 93306 with limited or follow-up echo codes (93307, 93308) on same date of service; use appropriate single code that matches service performed
Impact: Unbundling attempts result in automatic denials and potential audit flags; select single most appropriate code
Document contrast administration separately with +93352 when ultrasound contrast agent is used for enhanced LV opacification
Impact: Additional $60-$80 reimbursement when appropriate; requires specific documentation of contrast type, dosage, and medical necessity
Ensure timely filing of claims within 12 months for Medicare and verify individual payer timely filing limits to avoid administrative denials
