Tilt Table Testing — CPB 0299 | AETNA Coverage Update

Aetna modified CPB 0299 covering tilt table testing under CPT 93660, effective September 26, 2025. Here's what billing teams need to do.

Aetna, a CVS Health company, updated its tilt table testing coverage policy under CPB 0299 in Aetna's clinical policy bulletin system. The policy now explicitly covers CPT 93660 for two clinical indications: recurrent unexplained syncope and suspected postural orthostatic tachycardia syndrome (POTS). If your practice bills tilt table testing for Aetna members, verify your documentation maps directly to one of these two pathways before submitting claims.

Aetna Tilt Table Testing Coverage Criteria and Medical Necessity Requirements 2025

CPB 0299 in the Aetna system covers tilt table testing under two conditions. Both require that selection criteria are met before Aetna considers the procedure medically necessary.

Indication 1: Recurrent Unexplained Syncope

Aetna covers CPT 93660 when a member has recurrent unexplained syncope. Three documentation requirements must all be present: an inconclusive history and physical examination, and negative non-invasive tests of cardiac structure and function.

All three must be documented. Missing any one of them creates a medical necessity gap — and that gap becomes a claim denial. Make sure your ordering physicians are documenting the negative non-invasive workup explicitly, not just implied by the chart.

Indication 2: Suspected POTS

Aetna also covers tilt table testing as part of a diagnostic workup for suspected postural orthostatic tachycardia syndrome (POTS), coded as G90.A in ICD-10-CM. This is a distinct pathway from the syncope indication.

For POTS workups, the phrase "suspected" matters. You don't need a confirmed POTS diagnosis before ordering the test — that's the whole point of the workup. But your documentation needs to support why POTS is suspected. Symptoms like tachycardia on standing, dizziness (R42), and fatigue (R53.0–R83.8) should be documented before the test.

Provocative Agents (Isoproterenol)

The Aetna tilt table testing coverage policy also covers the use of provocative agents during the test. Specifically, isoproterenol administered alongside CPT 93660 is covered when criteria are met. The applicable HCPCS codes are J7657, J7658, J7659, and J7660 — covering both compounded and FDA-approved isoproterenol formulations in unit-dose and concentrated forms.

Bill the appropriate isoproterenol HCPCS code alongside CPT 93660 when the agent is used. Don't leave reimbursement for the drug component on the table by omitting the J code.

Prior Authorization

CPB 0299 does not explicitly state prior authorization requirements within the coverage criteria themselves. That said, Aetna plan-level prior authorization requirements vary by product. Check prior auth requirements at the individual plan level before scheduling, especially for POTS workups — which have seen increased utilization and scrutiny across payers.

Aetna Tilt Table Testing Billing Guidelines and Action Items 2025

1. Audit your open claims and upcoming orders before September 26, 2025.

The effective date is September 26, 2025. Any CPT 93660 claim hitting Aetna adjudication on or after that date is subject to the updated criteria. Pull your scheduled tilt table tests now and confirm each one maps to either syncope (with full documentation) or POTS workup.

2. Update your documentation checklist for the syncope pathway.

For the syncope indication, document three things explicitly: inconclusive history and physical, and negative non-invasive tests of cardiac structure and function. Build this into your pre-authorization and order review workflow. A claim denial under medical necessity is almost always a documentation problem — the test was appropriate, but the record didn't prove it.

3. Add ICD-10 specificity for POTS claims.

POTS has a dedicated ICD-10 code: G90.A. Use it. You also have I49.8 and R00.0 as supporting codes when applicable. Vague coding like R42 (dizziness) alone won't carry a medical necessity argument for tilt table testing. Code to the highest specificity the documentation supports.

4. Bill isoproterenol J codes when the drug is used.

If the performing provider uses isoproterenol during the tilt table test, bill the appropriate J code alongside CPT 93660. Use J7657 or J7660 for compounded formulations and J7658 or J7659 for FDA-approved non-compounded formulations. Check which formulation your facility uses and make sure it matches your charge capture setup.

5. Verify plan-level prior authorization requirements.

CPB 0299 sets coverage criteria — it doesn't override plan-level prior authorization rules. Before September 26, 2025, confirm your prior auth workflow accounts for Aetna product variations. Commercial, Medicare Advantage, and Medicaid managed care plans under the Aetna umbrella may have different requirements for tilt table testing billing.

6. Review the broader ICD-10 code set for POTS-adjacent conditions.

CPB 0299 supports a wide ICD-10 range, including Parkinson's disease (G20.A1–G20.C), multiple system atrophy (G96.810–G96.89), Chiari malformation (G93.5), and hypermobility syndrome (M35.7). These codes suggest Aetna recognizes autonomic dysfunction in neurological conditions as a legitimate clinical context for tilt table testing. If your patients present with these conditions alongside syncope or suspected POTS, make sure your ICD-10 coding reflects the full clinical picture.

If you're unsure how this policy applies to your specific Aetna plan mix, talk to your compliance officer before the September 26, 2025 effective date.

CPT, HCPCS, and ICD-10 Codes for Tilt Table Testing Under CPB 0299

Covered CPT Codes (When Selection Criteria Are Met)

Code	Type	Description Copy
93660	CPT	Evaluation of cardiovascular function with tilt table evaluation, with continuous ECG monitoring

Covered HCPCS Codes (When Selection Criteria Are Met)

Key ICD-10-CM Diagnosis Codes

A note on the Z79.890–Z79.899 codes: These codes cover long-term drug therapy and appear in CPB 0299 in the context of determining medication effectiveness in treating recurrent syncope. If your team bills tilt table testing to assess whether a current medication regimen is working, document that intent clearly in the clinical record and capture the appropriate Z79 code.

The breadth of this ICD-10 list — spanning autonomic neuropathy, Parkinson's, Chiari malformation, hypermobility syndrome, and multiple system atrophy — signals that Aetna views tilt table testing as appropriate across a wide range of autonomic and neurological conditions. That's genuinely useful for specialties beyond cardiology. Neurology practices billing CPT 93660 for patients with these diagnoses should confirm the documentation still meets the syncope or POTS pathway criteria, not assume the diagnosis code alone carries the claim.
