Cigna modified MM 0270 for tilt table testing, effective December 16, 2025. Here's what billing teams need to do.
Cigna Healthcare updated its coverage policy for tilt table testing under policy code MM 0270. This change affects CPT 93660, the code used for cardiovascular function evaluation with tilt table testing and continuous ECG monitoring. If your practice bills 93660 for patients with syncope, pay attention to what this update requires before you submit another claim.

Cigna Tilt Table Testing Coverage Criteria and Medical Necessity Requirements 2025
The Cigna tilt table testing coverage policy under MM 0270 covers CPT 93660 for a specific and narrow population: individuals with syncope where the cause has not been identified through standard evaluation. The ICD-10 diagnosis code that drives this claim is R55 — syncope and collapse.
Medical necessity under this policy centers on the diagnostic workup for unexplained syncope. Tilt table testing is not a first-line test. Cigna's position is that 93660 is appropriate after a standard evaluation has failed to identify the cause of the patient's syncopal episodes.
What does "standard evaluation" mean in practice? Think of it as the workup most electrophysiologists and cardiologists already order: history and physical, ECG, and in many cases, echocardiography and Holter monitoring. The tilt table test comes after those steps, not instead of them.
For billing teams, the real issue here is documentation. Medical necessity for CPT 93660 under the Cigna tilt table testing coverage policy depends on the chart clearly showing that prior diagnostic steps were taken and failed to explain the syncope. If the documentation doesn't tell that story, the claim is exposed.
Prior authorization requirements should be verified directly with Cigna before scheduling, as authorization requirements can vary by plan type and market. Check whether the specific Cigna plan — commercial, Exchange, or employer-sponsored — requires prior auth for 93660. Don't assume the answer is the same across all Cigna products.
Reimbursement for CPT 93660 is also tied to the medical necessity standard. If Cigna's clinical reviewers determine the indication wasn't met, expect a claim denial — and that denial will be difficult to overturn without thorough pre-service documentation. Build that documentation standard into your workflow now, before the effective date.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Unexplained syncope after standard evaluation | Covered | CPT 93660, ICD-10 R55 | Medical necessity documentation required; prior authorization may apply depending on plan |
| Syncope with identified cause (prior to tilt table testing) | Not Covered | CPT 93660 | If the cause is already established, tilt table testing does not meet medical necessity |
Cigna Tilt Table Testing Exclusions and Non-Covered Indications
Cigna's policy is clear on this: tilt table testing is not appropriate when the cause of syncope has already been identified. If the patient's workup has already established a diagnosis — say, a documented arrhythmia on Holter monitoring — billing CPT 93660 will not meet medical necessity under MM 0270.
The policy also limits coverage to syncope specifically. Billing 93660 with a diagnosis code outside R55 is a claim denial waiting to happen. Don't use tilt table testing charges to evaluate dizziness, presyncope without a documented syncopal event, or other symptoms that don't map to R55.
If your physicians are ordering tilt table tests for indications beyond unexplained syncope — as part of dysautonomia workups, for example, or POTS evaluations — check those cases carefully. The MM 0270 Cigna system coverage policy does not address those uses, and billing 93660 with a diagnosis outside R55 puts those claims at high risk.
Cigna Tilt Table Testing Billing Guidelines and Action Items 2025
| # | Action Item |
|---|---|
| 1 | Audit your CPT 93660 charge capture before December 16, 2025. Pull claims from the past 12 months. Confirm every 93660 submitted to Cigna carried ICD-10 R55 as the primary diagnosis. Any claim without R55 is a red flag — review those cases and determine whether an amendment or additional documentation is warranted. |
| 2 | Review documentation templates for pre-test workup evidence. The medical necessity standard for tilt table testing billing under MM 0270 requires evidence that standard evaluation failed to explain the syncope. Update your documentation templates — whether in your EHR or pre-authorization request forms — to include a structured summary of the prior workup. This one step prevents the most common denial scenario. |
| 3 | Confirm prior authorization requirements by Cigna plan type. Call your Cigna provider relations contact or check the Cigna provider portal to verify whether each relevant plan — commercial, Exchange, ASO — requires prior auth for CPT 93660. Build a plan-level reference sheet so your schedulers know what to do before the test is performed, not after. |
| 4 | Train your clinical staff on the covered indication. Physicians and APPs ordering tilt table tests need to understand that Cigna's coverage policy under MM 0270 is narrowly tied to unexplained syncope with a completed standard evaluation. Schedule a brief case-review session before the effective date of December 16, 2025. Walk through two or three real cases to illustrate what documentation does and doesn't support medical necessity. |
| 5 | Set up a denial tracking flag for CPT 93660. If your revenue cycle management system allows custom denial tracking, flag every 93660 denial from Cigna after December 16, 2025. Aggregate those denials monthly. If a pattern emerges — specific ordering providers, missing documentation elements, wrong diagnosis codes — you'll catch it early and fix it before it compounds. |
| 6 | If you bill for multiple syncope-related diagnoses, talk to your compliance officer. Some practices bill tilt table testing under broader dysautonomia or near-syncope presentations. If your clinical mix includes anything beyond clear R55 cases, loop in your compliance officer before the effective date. The MM 0270 Cigna system is specific. Billing outside its boundaries without compliance review is a real risk. |

CPT, HCPCS, and ICD-10 Codes for Tilt Table Testing Under MM 0270
Covered CPT Codes (When Selection Criteria Are Met)
| Code | Type | Description |

| 93660 | CPT | Evaluation of cardiovascular function with tilt table evaluation, with continuous ECG monitoring |
Key ICD-10-CM Diagnosis Codes
| Code | Description |
|---|---|
| R55 | Syncope and collapse |
A note on code pairing: CPT 93660 must link to R55 for the claim to align with Cigna's medical necessity standard under MM 0270. Claims submitted with 93660 paired to other diagnosis codes — without strong clinical justification and supporting documentation — are likely to face denial.
The CPT descriptor for 93660 includes continuous ECG monitoring as part of the procedure. Make sure your documentation confirms that monitoring occurred during the test. Missing that clinical detail in the procedure note is a simple fix, but it creates a significant vulnerability if Cigna requests records during a claim review.
Also check your facility's charge description master if you perform tilt table testing in a hospital outpatient or ambulatory setting. The 93660 code and its pairing with R55 need to be accurate in the CDM — not just in the physician billing workflow. Disconnects between facility and professional claims are a common source of confusion during Cigna audits.
