TL;DR: Cigna Healthcare modified MM 0368 covering pelvic denervation procedures — presacral neurectomy (PSN) and laparoscopic uterosacral nerve ablation (LUNA) — effective September 26, 2025. Here's what billing teams need to know before claims go out.
Cigna Healthcare updated its pelvic denervation procedures coverage policy under MM 0368, affecting two unlisted procedure codes: CPT 58578 (unlisted laparoscopy procedure, uterus) and CPT 64999 (unlisted procedure, nervous system). Both codes carry a "Medically Necessary when criteria are met" designation — which means your documentation has to be airtight before you bill. If your practice performs presacral neurectomy or LUNA for chronic pelvic pain and bills Cigna, this policy change affects your reimbursement directly.

Cigna Pelvic Denervation Coverage Criteria and Medical Necessity Requirements 2025
The Cigna pelvic denervation procedures coverage policy under MM 0368 covers two specific surgical interventions: presacral neurectomy (PSN) and laparoscopic uterosacral nerve ablation (LUNA). Both are performed for chronic pelvic pain. Both are covered — but only when defined medical necessity criteria are met.
This is where billing teams get into trouble. CPT 58578 and CPT 64999 are unlisted codes. Unlisted codes require manual review at Cigna. That means every single claim for these procedures goes through human eyes, and your documentation has to justify the surgery, the approach, and the indication before reimbursement happens.
Cigna classifies both PSN and LUNA as medically necessary when applicable criteria are satisfied. The policy does not provide blanket coverage for all chronic pelvic pain cases. The burden is on your team — and your clinical staff — to document that the patient meets those criteria before the claim leaves your system.
Prior authorization requirements for pelvic denervation procedures under Cigna should be confirmed at the plan level before scheduling. These are surgical procedures with unlisted codes. Assume prior auth is required unless your Cigna contract explicitly states otherwise. Don't wait until the day of surgery to check.
The real issue here is that "unlisted" status puts these procedures at constant claim denial risk. There's no clean RVU value attached to CPT 58578 or CPT 64999. Cigna's reviewers determine medical necessity — and reimbursement — case by case. That's not a reason to avoid billing these codes. It's a reason to treat every submission like it's going to appeal.
Cigna Pelvic Denervation Exclusions and Non-Covered Indications
The policy data for MM 0368 does not list specific exclusions by name. However, the "medically necessary when criteria are met" language is a conditional approval — not a blanket one. Any case that doesn't meet Cigna's documented criteria for PSN or LUNA is functionally non-covered.
In practice, this means pelvic denervation billing for indications outside of chronic pelvic pain — or for patients who haven't failed prior conservative treatments — carries significant denial risk. Cigna reviewers will look for evidence that surgery was clinically warranted, not just clinically performed.
If you're unsure whether a specific patient's case meets the criteria threshold under MM 0368, talk to your compliance officer before submitting. Unlisted codes with conditional coverage are exactly the situation where a pre-submission review saves your team from a denial spiral.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Presacral neurectomy (PSN) for chronic pelvic pain | Covered when criteria met | CPT 64999 | Unlisted code — manual review required; document medical necessity thoroughly |
| Laparoscopic uterosacral nerve ablation (LUNA) for chronic pelvic pain | Covered when criteria met | CPT 58578 | Unlisted laparoscopy code — manual review required; prior auth likely needed |
| PSN or LUNA without meeting Cigna's criteria | Not Covered | CPT 58578, CPT 64999 | Conditional coverage only; non-compliant cases will be denied |
Cigna Pelvic Denervation Billing Guidelines and Action Items 2025
These are the steps your billing team needs to take before and after the effective date of September 26, 2025.
| # | Action Item |
|---|---|
| 1 | Confirm prior authorization requirements for CPT 58578 and CPT 64999 now. Call your Cigna provider relations contact or check the provider portal directly. Don't rely on previous authorizations or assumptions from prior cases. The policy was modified — treat it as new. |
| 2 | Update your charge capture workflow to flag both CPT 58578 and CPT 64999 as requiring documentation review before submission. These are unlisted codes. Every claim needs an operative report, a clear diagnosis, and documentation that the patient met Cigna's medical necessity criteria for pelvic denervation. |
| 3 | Audit any open or pending claims for PSN or LUNA that were submitted before September 26, 2025. If those claims are still in process, the modified policy may apply. Check with your Cigna rep on how the payer handles in-flight claims during a policy change window. |
| 4 | Train your clinical documentation team on what "criteria met" means for these procedures. Billing can't fix a documentation problem after the fact. Your surgeons and clinical staff need to know what Cigna requires — specifically that PSN and LUNA coverage is conditional, not automatic — before they write their operative notes. |
| 5 | Build an appeal template for CPT 58578 and CPT 64999 denials now, before you need it. Unlisted codes get denied often, even when the case is clinically appropriate. A pre-built appeal citing MM 0368, the specific medical necessity criteria, and the operative documentation will cut your appeal turnaround significantly. |
| 6 | Verify plan-level coverage before billing. MM 0368 is a Cigna corporate policy, but individual Cigna plan contracts can vary. Some self-funded plans may have different coverage terms. Check the specific member's plan before assuming the corporate policy controls. |
| 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 Pelvic Denervation Under MM 0368
Covered CPT Codes (When Medical Necessity Criteria Are Met)
| Code | Type | Description |
|---|---|---|
| 58578 | CPT | Unlisted laparoscopy procedure, uterus |
| 64999 | CPT | Unlisted procedure, nervous system |
Both codes are covered under MM 0368 when Cigna's medical necessity criteria for presacral neurectomy or laparoscopic uterosacral nerve ablation are satisfied. Neither code has a standard fee schedule value — reimbursement is determined by Cigna on a case-by-case basis using comparable procedure benchmarks.
No HCPCS codes are listed in the current MM 0368 policy data. No ICD-10-CM diagnosis codes are specified in the policy data for this coverage policy. Your ICD-10 coding should reflect the chronic pelvic pain diagnosis and any underlying etiology — but confirm your specific codes with your clinical coder, not this policy alone.
