This policy governs coverage of minimally invasive ablation and neural therapy procedures (e.g., radiofrequency ablation, cryoablation, cryoneurolysis, alcohol injections) used to treat headache and other pain conditions for Blue Cross Blue Shield of North Carolina members.
No material clinical or coverage changes in this revision.
Coverage Determinations
Not covered (investigational)
The following are considered investigational for all applications and diagnoses:
This policy addresses coverage for minimally invasive ablation procedures used in the management of headache and other pain conditions. Examples include, but are not limited to, radiofrequency ablation (RFA), cryoablation/cryoneurolysis, and intralesional alcohol, anesthetic, or steroid injections. Per the policy, these minimally invasive ablation procedures of peripheral nerves are considered investigational for all applications and diagnoses and therefore are not covered by BCBSNC. Providers should refer to related policy guidance for procedures involving facet joint pain, which are treated separately.
Conservative, noninvasive management (for example, orthotics, activity modification, NSAIDs, physical therapy, or steroid injections) is described in the policy as typical first‑line care for conditions such as Morton neuroma, plantar fasciitis, and knee osteoarthritis prior to consideration of invasive ablation techniques; however, the policy does not specify mandatory trial lengths or explicit durations for conservative therapy in these clinical scenarios.
The policy specifically states that ablation of peripheral nerves to treat pain is investigational for all applications and diagnoses except for an explicit exception for facet joint pain. In other words, radiofrequency ablation or cryoneurolysis directed at peripheral sensory nerves for pain relief is investigational and not covered across indications other than facet joint–related procedures, which are addressed under other coverage guidance.
Services and procedures designated as investigational in this policy are not covered by BCBSNC. The policy language is clear: BCBSNC does not provide coverage for investigational services or procedures, including minimally invasive ablation techniques and peripheral nerve ablation when labeled investigational in this document. Providers should verify member benefits and prior authorization requirements in the Member's Benefit Booklet, and be aware that claims for investigational procedures are subject to denial and BCBSNC may request medical records to substantiate medical necessity for billed services.
The policy reviews evidence across several specific indications — including Morton neuroma, other peripheral neuromas, plantar fasciitis, knee osteoarthritis, occipital neuralgia, and cervicogenic headache — and finds the overall body of literature inadequate to support coverage. For Morton neuroma, available evidence is limited to heterogeneous case series and small studies of alcohol injections, RFA, and cryoablation, with insufficient controlled data to demonstrate net health benefit. For plantar fasciitis and knee osteoarthritis, randomized trials and systematic reviews exist but are small, heterogeneous, or of low quality and do not provide consistent, durable benefit; cryoneurolysis trials for knee OA showed some short‑term pain reductions but inconsistent longer‑term effects. For occipital neuralgia and cervicogenic headache, randomized data are limited or low quality, and any temporary benefits observed were not consistently superior to comparator injections. Across these indications, the policy concludes the evidence is insufficient to establish improved net health outcomes; therefore these applications of ablation or cryoneurolysis are considered investigational and not covered.
Applicable Codes
Provider Requirements and Notices
Verify benefits and prior authorization
Verify member benefits and any required prior authorization before performing procedures by reviewing the Member’s Benefit Booklet and the member’s specific benefit language, since benefits may vary by plan.
- Review Member's Benefit Booklet for benefit availability and prior authorization requirements.
- Confirm benefit design-specific coverage before scheduling procedures.
Submit applicable codes and be ready to document medical necessity
Use the listed CPT/HCPCS codes when submitting claims and be prepared to provide medical records to support medical necessity for services billed with these codes.
Attempt conservative therapy before invasive procedures
Document and attempt conservative, noninvasive management before considering invasive ablation procedures; typical initial options cited include orthotics/metatarsal pads, heel cups, activity modification, NSAIDs, and local steroid injections.
- Conservative measures listed: metatarsal pads, orthotic devices, heel cups, activity modification, NSAIDs, and local steroid injections.
- The policy describes these as typical first-line management though it does not specify mandatory trial durations.
Provider note — verify benefits and prepare documentation
Follow the provider-facing guidance in the policy: consult the Member’s Benefit Booklet for benefit availability and be prepared to supply clinical records to support any request for coverage, as BCBSNC may request documentation to determine medical necessity.
- Consult treating physician for technical and indication-specific questions as recommended in policy guidance.
- Be prepared to submit full clinical records when requested.
Review member benefit language
Review member benefit language for each patient prior to providing services; the Member’s Benefit Booklet determines whether benefits are available and benefits vary by plan.
- Do not assume coverage; check the member’s specific benefit design in the Member’s Benefit Booklet.
- Confirm prior authorization and coverage limits as applicable.
Provide complete medical records when requested
If requested, submit complete medical records to BCBSNC to support medical necessity determinations; letters of support alone are insufficient unless they include all specific information needed for the determination.
- Provide complete medical records when requested; letters of support/explanation are not sufficient unless they include all required information.
- Maintain documentation of prior conservative treatments and prior management to support clinical decisions.
Denial risk — investigational status of ablation procedures
Claims for minimally invasive ablation procedures (including RFA, cryoablation, and alcohol/anesthetic/steroid injections), radiofrequency ablation of peripheral nerves, and cryoneurolysis of peripheral nerves will be denied as investigational except where ablation for facet joint pain may be covered per other policy guidance.
- Minimally invasive ablation procedures are considered investigational for all applications and diagnoses and are not covered.
- Radiofrequency ablation and cryoneurolysis of peripheral nerves are investigational for all applications and diagnoses and will be denied.
Investigational procedures may be denied
Procedures identified as investigational (for example, minimally invasive ablation procedures, radiofrequency ablation of peripheral nerves, and cryoneurolysis) are subject to denial; do not rely on coverage unless specifically authorized by applicable policy exceptions.
- Ablation of peripheral nerves to treat pain is investigational for all applications and diagnoses except facet joint pain.
- Claims for these investigational procedures will not be covered by BCBSNC.
Background and Scope
Peripheral neuromas (including Morton neuroma) typically present as neuropathic pain from a damaged or entrapped peripheral nerve and may manifest weeks to months after injury with symptoms such as localized burning, tingling, or lancinating pain exacerbated by activity or compression. Morton neuroma is a compression neuropathy of the common digital nerve, frequently located between the third and fourth metatarsal heads; diagnosis is primarily clinical although imaging (plain radiographs, MRI, ultrasound) may be used to aid assessment. Plantar fasciitis presents with heel pain related to degenerative irritation at the plantar fascia insertion and is commonly managed conservatively. Knee osteoarthritis produces chronic joint pain and functional limitation in older adults; ablative procedures such as genicular nerve RFA or cryoneurolysis have been studied as a potential nonoperative pain management option but study methods and results are heterogeneous. Occipital neuralgia and cervicogenic headache are headache syndromes thought to arise from peripheral nerve or cervical structures; RFA and cryoneurolysis have been evaluated but randomized trial evidence is limited and inconclusive. RFA uses heat via an electrode to coagulate tissue and destroy peripheral sensory nerve endings, while cryoneurolysis applies extreme cold to induce Wallerian degeneration with potential for nerve regeneration over months; both techniques and related injection-based neural therapies have proposed mechanisms but lack consistent high-quality evidence of sustained clinical benefit across the indications described.

Diagnostic and Technical Imaging Notes
Document clinical findings; imaging may be adjunctive for Morton neuroma
Although imaging (plain radiographs, MRI, or ultrasonography) may aid the diagnosis of Morton neuroma, recognize that objective findings are primarily clinical and document clinical exam findings (eg, Mulder sign, toe splaying) in the record.
- Imaging may be supportive but diagnosis is primarily clinical
- Document clinical exam findings such as Mulder sign or a palpable click
No mandated imaging requirement for cryoneurolysis/RFA — document technique
No specific imaging modality is mandated for cryoneurolysis or RFA; be aware that technical issues (eg, optimal probe insertion method, number/duration of applications) remain unresolved and the policy does not require a particular imaging technique.
- Policy does not mandate ultrasound guidance versus anatomic landmark techniques
- Document technique used and rationale in the chart
Not Covered Procedures
Minimally invasive ablation procedures (including but not limited to RFA, cryoablation/cryoneurolysis, and alcohol, anesthetic, or steroid injections) are classified as not covered (investigational) for all applications and diagnoses in this policy. Providers should verify member benefits and prior authorization requirements; claims for investigational procedures are subject to denial and BCBSNC will not provide coverage for investigational services.
