Coverage Determination

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Not medically necessary / Not covered

Covered when ALL of the following are met:

Pulsed RF denervation coverage: Pulsed radiofrequency denervation for the treatment of chronic spinal/back pain is considered not medically necessary or not covered because the evidence is insufficient to determine the effects on health outcomes.

Applies to commercial products per policy text.

Provider Responsibilities and Billing Guidance

Prior Authorization

Prior Authorization and Billing

Prior Authorization: Not applicable. There is no separate prior authorization requirement specified for pulsed radiofrequency denervation in this policy. Providers should verify member-specific prior authorization requirements and any plan- or group-level preauthorization rules by checking the member’s Benefit Booklet/Evidence of Coverage or contacting the payer’s provider call center prior to scheduling services.

Not applicable

Documentation Required

Benefit and Member-Specific Documentation

Benefit and member-specific coverage: Benefits may vary between groups and contracts. Providers must refer to the member’s Benefit Booklet, Evidence of Coverage, Subscriber Agreement, or employer agreement for benefit-specific coverage determinations (including whether services deemed not medically necessary are covered). Those documents supersede this medical policy. For member-specific benefits or eligibility questions, contact the payer’s provider call center. If a service is determined not to be a covered benefit, providers may not bill the member unless the member has been informed and provided written agreement to pay.

Refer to member Benefit Booklet/Evidence of Coverage for applicable benefits and coverage.
Contact provider call center for member-specific eligibility and benefit questions.
Do not bill members for non-covered services unless member provided informed written consent to pay.

Background and Mechanism

Pulsed RF delivers short bursts of high‑voltage electrical current in the radiofrequency range that are applied intermittently so tissue is not heated sufficiently to cause coagulation. Probe tip temperatures for pulsed RF are typically maintained at or below 42°C, and the technique is intended to modulate nerve function (eg, affect small unmyelinated fiber transmission) without producing the thermal lesioning seen with conventional thermal RF.

Key Definitions

Pulsed radiofrequency (pulsed RF) denervation — definition and intended effect

DefinitionAn interventional pain procedure that delivers short bursts of high‑voltage radiofrequency current to modulate nerve function without producing tissue coagulation, intended to relieve facet‑origin neck and back pain.

Intended effectProvide pain relief for facet joint–mediated chronic spinal/back pain by disrupting transmission across small unmyelinated nerve fibers without permanent nerve destruction.

Mechanism noteProbe tip temperatures typically do not exceed 42°C, avoiding the coagulative temperatures seen with thermal RF (~60°C).

Regeneration considerationNerves may regenerate after denervation, and repeat procedures can be required to maintain pain relief.

Facet joint diagnosis confirmation — diagnostic medial branch blocks described as typical confirmation method

Typical confirmation methodDiagnosis of facet joint pain is typically confirmed by a positive response to diagnostic medial branch (facet joint) nerve blocks.

Role in pathwayDiagnostic medial branch blocks are referenced as part of confirming facet origin prior to considering denervation procedures.

Implication for treatmentA documented response to diagnostic nerve block is used to attribute pain to the facet joint before proceeding with interventional denervation techniques.

Diagnostic and Conservative Treatment Requirements

Diagnostic medial branch/facet joint blocks are referenced as part of diagnostic confirmation.

Diagnostic confirmation of facet joint–mediated pain should include response to diagnostic medial branch (facet joint) nerve blocks as part of the evaluation prior to denervation procedures.

Diagnostic confirmation: Diagnosis of facet joint pain is confirmed by a clinically meaningful response to diagnostic medial branch (facet joint) nerve blocks prior to considering denervation procedures.

Policy references medial branch/facet joint blocks for confirmation; specific block protocols (eg, number, anesthetic used, percent pain relief) are not specified in this policy.

Frequency and Repeat Treatment Limits

Pulsed radiofrequency denervation — frequency/limits related entry

Policy frequency limitsNo specific frequency or repeat‑procedure interval is specified in the policy for pulsed RF denervation.

Repeat proceduresThe policy notes that nerves regenerate and repeat procedures may be required, but does not define limits or intervals for repeats.

Benefit variabilityBenefits and coverage details (including any limits) may vary by group or contract; refer to the member's Benefit Booklet or Evidence of Coverage.

Coverage stance impactPulsed RF is considered not medically necessary for chronic spinal/back pain due to insufficient evidence, which may result in claim denials regardless of frequency considerations.

Imaging and Diagnostic Requirements

Note

Diagnostic nerve blocks referenced; imaging not specified

The policy references diagnostic medial branch or facet joint nerve blocks for confirming facet-origin pain but does not specify any imaging requirements.

Diagnosis confirmed by response to nerve blocks; imaging requirements are not stated in the policy.
