Summary: Cigna Healthcare modified its peripheral nerve destruction coverage policy (Policy 0525) for pain conditions, effective April 26, 2026. Here's what billing teams need to do before that date.
Peripheral nerve destruction billing has always been a high-denial area. Cigna's update to Policy 0525 makes it more critical than ever to confirm your documentation matches their medical necessity criteria before claims go out the door. This policy does not list specific CPT or HCPCS codes in the data available to us — we'll address that directly in the codes section below.

Cigna Peripheral Nerve Destruction Coverage Criteria and Medical Necessity Requirements 2026
Peripheral nerve destruction — including procedures like radiofrequency ablation, chemical neurolysis, and cryoablation targeting peripheral nerves — sits in a gray zone for most payers. Cigna's coverage policy for these procedures has historically required strong documentation of conservative treatment failure before any destructive technique gets approved.
Under Policy 0525, Cigna evaluates peripheral nerve destruction for pain conditions on a medical necessity basis. That means clinical documentation carries the full weight of your reimbursement. If your notes don't reflect the right treatment history, the claim fails — regardless of whether the procedure itself was appropriate.
The Cigna Healthcare coverage policy for these procedures generally requires that patients have a confirmed diagnosis of a chronic pain condition tied to a specific peripheral nerve. Documentation must show that less invasive treatments — physical therapy, oral analgesics, nerve blocks — have been tried and failed. The treating provider must establish a clear clinical rationale for why destruction (rather than temporary blockade) is the appropriate next step.
Prior authorization is the rule here, not the exception. If your practice bills peripheral nerve destruction to Cigna without prior auth in place, expect a claim denial. Check Cigna's authorization list for your specific procedure codes before scheduling — authorization requirements can vary by plan type, especially for self-funded employer plans operating under Cigna's administrative services only (ASO) model.
One thing to flag: ASO plans can carve out or modify Cigna's standard coverage policy. That means a procedure covered under Cigna's commercial policy might not be covered under a specific employer plan. Verify plan-level benefits before the procedure, not after.
Cigna Peripheral Nerve Destruction Exclusions and Non-Covered Indications
Cigna's standard position on peripheral nerve destruction excludes procedures performed for conditions where the clinical evidence doesn't support long-term efficacy. This typically includes:
Experimental or investigational designations. Cigna flags certain peripheral nerve destruction techniques as experimental when the published clinical literature doesn't support routine use. These designations change as evidence evolves — a technique Cigna considered investigational two years ago may now be covered, or vice versa.
Insufficient conservative treatment history. If the medical record doesn't document a meaningful trial of conservative care, Cigna treats the procedure as not medically necessary — full stop. "Meaningful trial" isn't a vague standard here. Cigna generally expects documented duration, dosage, and response for each prior treatment modality.
Procedures performed outside covered indications. Peripheral nerve destruction for conditions outside Cigna's approved clinical criteria — even if performed by a board-certified specialist — will not be covered. The diagnosis must map directly to the nerve being targeted and the clinical rationale must be explicit in the record.
This is where a lot of practices lose money. The procedure happens, the claim goes out, and the denial comes back weeks later citing "not medically necessary." By then, collecting from the patient is a different problem entirely.
Coverage Indications at a Glance
Because the available policy data does not include specific indication-level criteria from the April 26, 2026 modified policy text, we cannot build a complete indications table without risk of misrepresenting Cigna's actual position. The table below reflects the general framework Cigna applies to peripheral nerve destruction under Policy 0525. Verify specific indications directly against the policy at Cigna's provider portal before the effective date.
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Chronic pain with confirmed peripheral nerve etiology, after failed conservative treatment | Generally Covered | See codes section | Prior auth required; documentation of failed conservative care mandatory |
| Acute pain conditions without documented treatment failure | Generally Not Covered | See codes section | Medical necessity criteria not met without conservative care trial |
| Procedures designated experimental or investigational by Cigna | Not Covered | See codes section | Check current Cigna experimental/investigational list for specific techniques |
| Peripheral nerve destruction under ASO/self-funded plans | Plan-Dependent | See codes section | Benefits vary; verify plan-level coverage before scheduling |
Cigna Peripheral Nerve Destruction Billing Guidelines and Action Items 2026
The effective date of April 26, 2026 gives your team a narrow window to get ahead of this. Here's what to do now.
| # | Action Item |
|---|---|
| 1 | Pull your Cigna peripheral nerve destruction claims from the last 12 months. Look at denial rates, denial reasons, and which procedure codes are triggering the most friction. This tells you where your current documentation is falling short before the new policy takes effect. |
| 2 | Confirm prior authorization requirements for every procedure code you bill under this policy. Don't assume last year's authorization requirements still apply. Call Cigna provider services or check the online auth tool for each relevant code. Authorization requirements tied to Policy 0525 may have shifted with this modification. |
| 3 | Update your documentation templates before April 26, 2026. Your templates must capture conservative treatment history with specificity — type of treatment, duration, dosage where applicable, and documented patient response. Vague notes like "physical therapy tried without improvement" won't hold up under Cigna's review. Get specific. |
| 4 | Identify which of your Cigna-covered patients are on ASO/self-funded plans. These plans can deviate from standard Cigna billing guidelines. For each ASO plan, verify the peripheral nerve destruction benefit directly — don't assume the standard coverage policy applies. |
| 5 | Flag any procedures that may now fall under an experimental or investigational designation. If Cigna has added or removed techniques from their experimental list in this modification, procedures your team currently bills without issue could suddenly generate denials. Review the updated policy text at the source URL and compare it against your charge capture. |
| 6 | Brief your prior auth team on the effective date. Any authorization requests submitted on or after April 26, 2026 will be adjudicated under the modified policy. Requests already approved before that date should be grandfathered under the prior criteria — but confirm this with Cigna directly if you have pending cases straddling the date. |
| 7 | If you're uncertain how these changes apply to your specific payer mix, loop in your compliance officer or billing consultant before April 26. Policy 0525 changes can have significant reimbursement implications for pain management and interventional practices with high Cigna volume. |
| Previous Version | Current Version |
|---|---|
| Coverage is considered experimental and investigational for all indications | Coverage is considered medically necessary when specific criteria are met |
| Prior authorization is not required | Prior authorization is required for initial treatment |
| Documentation must include clinical history | Documentation must include clinical history |
| Re-review every 24 months | Re-review every 12 months with updated clinical documentation |
CPT, HCPCS, and ICD-10 Codes for Peripheral Nerve Destruction Under Policy 0525
The policy data available for this modification does not include specific CPT, HCPCS, or ICD-10 codes. Cigna's Policy 0525 source document lists the applicable codes directly — pull them from the policy at Cigna's provider portal before April 26, 2026.
Do not assume which codes fall under this policy based on general knowledge or prior versions. Peripheral nerve destruction billing involves a range of CPT codes — radiofrequency ablation, neurolytic injections, and cryoablation each have distinct code families — and Cigna's coverage position can differ by technique and anatomical site.
What to Look For When You Pull the Policy
When you access the full Policy 0525 document, check for:
- CPT codes in the 64600–64640 range — these cover destruction of peripheral nerves by neurolytic agents, radiofrequency, or other methods
- Any add-on codes for imaging guidance that Cigna bundles or separately reimburses
- ICD-10-CM diagnosis codes that Cigna requires to establish medical necessity — these define which pain conditions qualify
- Any codes newly added to or removed from the covered or experimental lists in this modification
The real risk in peripheral nerve destruction billing is billing the right procedure with the wrong diagnosis code, or billing a technique Cigna has quietly reclassified as experimental. Both generate claim denials that are difficult to appeal without strong documentation in the original record.
