TL;DR: Cigna Healthcare modified MM 0350, its vagus nerve stimulation coverage policy, effective February 14, 2026. Here's what billing teams need to do.
Cigna Healthcare updated Coverage Policy MM 0350 for implantable vagus nerve stimulation (VNS), effective February 14, 2026. The policy governs medical necessity criteria for CPT codes 64568, 64553, 61886, and 0908T, plus 14 HCPCS device codes including C1767, C1778, L8679, and L8680. One HCPCS code — C1607 — is explicitly classified as not medically necessary for implantable integrated neurostimulator systems. If you bill VNS procedures for Cigna members, this coverage policy warrants a full review before claims go out the door.

Cigna Vagus Nerve Stimulation Coverage Criteria and Medical Necessity Requirements 2026
The core of MM 0350 is straightforward: Cigna covers implantable vagus nerve stimulation when specific medical necessity criteria are met. The policy centers on medically intractable seizures as the primary covered indication. "Medically intractable" means the patient has failed adequate trials of appropriate antiepileptic drug therapy — not just one medication, and not medications abandoned for tolerability alone.
Cigna's coverage position applies to implantation, electrode placement, and pulse generator insertion or replacement. CPT 64568 covers open implantation of a cranial nerve (vagus nerve) neurostimulator electrode array and pulse generator. CPT 64553 covers percutaneous implantation of a neurostimulator electrode array at the cranial nerve. CPT 61886 covers insertion or replacement of a cranial neurostimulator pulse generator or receiver, whether direct or inductive coupling. CPT 0908T covers open implantation of an integrated neurostimulation system at the vagus nerve, including analysis and programming.
All four CPT codes are considered medically necessary when the applicable criteria in MM 0350 are met. This is not a blanket approval. The criteria exist, and Cigna will look for them in the medical record when a claim comes in — or before the procedure, if prior authorization is required.
Speaking of prior authorization: VNS implantation is a surgical procedure with substantial reimbursement attached. Do not assume prior auth isn't required for your Cigna contracts. Check plan-specific requirements before scheduling implantation. A claim denial on a procedure this expensive is a significant revenue cycle problem, not just a paperwork nuisance.
The policy also addresses other indications beyond epilepsy. The language "and other indications" in the policy title matters. What those indications are and whether they meet Cigna's criteria is something your clinical and billing teams need to confirm against the full MM 0350 document. If your practice bills VNS for depression or other off-label uses, verify the specific coverage position for each indication before billing.
Cigna Vagus Nerve Stimulation Exclusions and Non-Covered Indications
One HCPCS code stands out in this policy as explicitly not medically necessary: C1607.
C1607 describes a neurostimulator, integrated (implantable), rechargeable, with all implantable and external components. Cigna has classified this code as not medically necessary when used to report an implantable integrated neurostimulation system for vagus nerve stimulation.
This is a meaningful distinction. If your practice has adopted newer integrated VNS platforms — the kind that bundle the generator, lead, and external components into a single device system — and you're billing C1607 to Cigna, expect denials. The code is explicitly excluded under this coverage policy.
The practical takeaway: map your device to the correct HCPCS code before submission. C1767 (non-rechargeable implantable neurostimulator generator), C1820 (generator with rechargeable battery and charging system), and L8679 (implantable neurostimulator pulse generator, any type) are all in the covered column when criteria are met. C1607 is not. That's not a gray area — that's a denial waiting to happen.
If your device vendor markets a product that maps to C1607, flag this immediately with your billing team and your compliance officer. You may need to reclassify how you're coding the device component, or you may need to confirm with Cigna whether coverage exists under any other mechanism.

Cigna Vagus Nerve Stimulation Billing Guidelines and Action Items 2026
The effective date is February 14, 2026. For dates of service on or after that date, MM 0350 as modified governs. Here's what your billing team needs to do now.
| # | Action Item |
|---|---|
| 1 | Pull every open VNS claim and confirm device code accuracy. Cross-reference each HCPCS code against the covered and non-covered lists in MM 0350. If you see C1607 on any active Cigna claim, pull it before submission and determine the correct replacement code. Submitting C1607 to Cigna for VNS is a guaranteed denial under this coverage policy. |
| 2 | Confirm prior authorization requirements for all scheduled VNS implantations. Contact Cigna provider relations or check your contract for PA requirements on CPT 64568 and 0908T specifically. These are high-dollar surgical procedures. A missing prior auth on an implantable neurostimulator case is not a simple fix — it can trigger a full write-off. |
| 3 | Audit your charge capture for CPT code mapping. Make sure your charge capture system maps VNS open implantation to CPT 64568 or 0908T correctly. These two codes are not interchangeable — 0908T specifically covers an integrated neurostimulation system with analysis and programming included. If your facility uses 0908T, confirm that the device and service components match what's described in that code before you bill. |
| 4 | Verify indication documentation in the medical record before billing. Cigna's VNS coverage is criteria-based. The record must support medically intractable epilepsy — or whatever other indication is being claimed. Document failed antiepileptic drug trials explicitly. Vague documentation is the fastest path to a medical necessity denial on VNS cases. |
| 5 | Flag any non-epilepsy VNS cases for secondary review. The policy covers "other indications," but does not spell them out in the summary. If your practice implants VNS for treatment-resistant depression or another non-epilepsy indication, get explicit coverage confirmation from Cigna before billing. Talk to your compliance officer if you're unsure whether your documentation supports the indication under MM 0350. |
| 6 | Update your denial management workflow to catch C1607. Add C1607 as a flagged code in your remittance review process. If Cigna denies a claim citing MM 0350 and C1607 is on it, the path forward is reclassification — not an appeal arguing medical necessity, since Cigna has explicitly excluded this code. |
