Billing tips

Verify medical necessity documentation explicitly states syncope or presyncope as the indication, with documentation that basic cardiac workup (ECG, possibly echocardiogram) was inconclusive
Impact: Prevents 40-60% of medical necessity denials which are the most common reason for 93660 claim rejections
Document total test duration and all phases (baseline supine, tilt phase with degree of tilt, any pharmacologic challenge, and recovery), as incomplete documentation triggers audits
Impact: Reduces audit risk and recoupment exposure; ensures full $159.14 reimbursement rather than partial payment or denial
Bill 93660 as a global code when performed in physician-owned facilities; split into 26 and TC modifiers only when technical and professional components are provided by different entities
Impact: Improper modifier use can result in 50% underpayment if global service is incorrectly split
Do not bill 93660 on the same day as comprehensive cardiac stress testing (93015-93018) without modifier 59 and clear documentation of separate medical necessity
Impact: Prevents NCCI bundling edits that result in automatic denial of the tilt table service
Ensure continuous ECG monitoring and blood pressure measurements at defined intervals (typically every 2-3 minutes) are documented in the report
Impact: Meets Medicare LCD requirements; absence of this documentation can trigger $159.14 recoupment in post-payment audits
For commercial payers, obtain prior authorization when required, as many private insurers classify tilt table testing as requiring pre-certification

Frequently asked questions

What is the Medicare reimbursement rate for CPT 93660 in 2025?

The 2025 Medicare national average reimbursement for CPT 93660 is $159.14 for both facility and non-facility settings, based on 4.92 total RVUs (1.89 work RVU, 2.95 PE RVU, 0.08 MP RVU) and the 2025 conversion factor of 32.3465.

Can CPT 93660 be billed with an office visit on the same day?

Yes, CPT 93660 can be billed with an E/M service on the same day if the E/M service is separately identifiable and significant, typically requiring modifier 25 on the E/M code. However, the decision to order the tilt table test alone does not qualify as a separate E/M service; there must be additional evaluation and management beyond what's necessary to perform the tilt table evaluation.

What diagnosis codes support medical necessity for tilt table testing?

Primary covered diagnoses include R55 (syncope and collapse), R42 (dizziness and giddiness), I95.1 (orthostatic hypotension), G90.A (postural orthostatic tachycardia syndrome), and R53.83 (other fatigue). Documentation must show the patient has experienced syncopal or presyncopal episodes and that basic cardiac evaluation has been performed or is non-diagnostic.

How long does a tilt table test need to be to bill CPT 93660?

While CPT 93660 does not specify a minimum duration, standard protocols typically require 20-45 minutes of tilt time at 60-80 degrees, plus baseline and recovery periods. The total procedure usually lasts 30-60 minutes. Documentation must show adequate test duration to assess hemodynamic response and symptom reproduction; very brief tests may not meet payer coverage requirements.

What is the difference between CPT 93660 and cardiac stress testing codes?

CPT 93660 (tilt table evaluation) assesses autonomic nervous system response to postural changes and is used for syncope evaluation, while cardiac stress testing (93015-93018) evaluates cardiac function during exercise or pharmacologic stress to diagnose coronary artery disease. These are distinct diagnostic procedures with different clinical indications and should not typically be performed on the same day unless separate medical necessity is documented.

Do I need to split CPT 93660 into professional and technical components?

Split billing with modifier 26 (professional) and TC (technical) is only required when different entities provide the interpretation versus the technical service. If the same physician practice or facility provides both components, bill 93660 as a global service without modifiers. Improper splitting when providing global service results in underpayment.

Is prior authorization required for CPT code 93660?

Medicare typically does not require prior authorization for 93660, but many commercial payers and Medicare Advantage plans do require pre-certification for tilt table testing as it's considered an advanced diagnostic procedure. Always verify authorization requirements with the specific payer before scheduling to avoid denial. Authorization requirements vary significantly by payer and plan.
