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.

Coverage Criteria for Discectomy Procedures

Minimally invasive discectomy - not proven superior

The following minimally invasive discectomy techniques are considered not proven superior to existing technologies and are not supported:

Minimally invasive discectomy techniques not proven superior: Percutaneous lumbar discectomy (manual or automated and/or MILD); percutaneous laser discectomy (PLD); laser-assisted disc decompression (LADD); percutaneous laser disc decompression (PLDD); percutaneous nuclectomy; percutaneous endoscopic discectomy; endoscopic laser percutaneous discectomy (LASE); endoscopic spinal surgery system; interspinous/interlaminar process stabilization/spacer device.

Procedures and devices listed in the CPT and HCPCS "Do Not Support Coverage Criteria" tables are explicitly identified in this policy as not supporting coverage. Examples include interlaminar/interspinous process stabilization/distraction devices (CPT 22867–22870) and specified percutaneous decompression procedures (CPT 62330, 62331; HCPCS C1821, S2348). Claims for these codes may be denied if submitted as supporting the covered indications in this policy.

When this clinical policy conflicts with state Medicaid coverage provisions, the state Medicaid provisions take precedence. Providers and billing staff should consult the applicable state Medicaid manual for any differing coverage rules before applying the clinical criteria in this policy.

A range of minimally invasive discectomy (MID) techniques listed in this policy are considered not proven superior to existing technologies and therefore are not supported for coverage. Enumerated examples include percutaneous lumbar discectomy (manual or automated/MILD), percutaneous laser discectomy, laser-assisted disc decompression, percutaneous nuclectomy, percutaneous endoscopic discectomy, endoscopic laser percutaneous discectomy (LASE), endoscopic spinal surgery systems, and interspinous/interlaminar process stabilization/spacer devices. The policy’s CPT and HCPCS "do not support" tables reflect this not-supported stance for the specific codes listed.

inv-10: Physical therapy or prescribed home exercise program — duration requirement

Required duration≥ four weeks of physical therapy or a prescribed home exercise program (or documentation of inability to tolerate)

ContextPart of conservative therapy prerequisites that must be attempted within the last year for most cases without severe motor deficit

Policy referenceCriteria I.C.1.b.ii.a) and I.C.2.a. in the clinical criteria

inv-11: Activity modification — duration requirement

Required duration≥ four weeks of activity modification

Context

Provider Actions, Prior Authorization, and Documentation

Prior Authorization

Prior Authorization Required

Prior authorization is required per the member's plan procedures before scheduling disc decompression surgeries. Coverage is contingent upon meeting the clinical criteria in this policy and any applicable plan administrative requirements.

Prior authorization required for listed procedure codes supporting coverage.
Coverage decisions subject to plan administrative policies and prior authorization process.

Denial Risk

Denial Risk from Coverage Terms

Services that are not consistent with the coverage terms of this policy may be denied. Claims for procedures, devices, or codes that do not meet the medical necessity criteria or are listed as not supporting coverage are at risk for denial.

Claims using interspinous/interlaminar devices (e.g., 22867-22870, C1821) or percutaneous decompression codes listed as not supporting coverage (e.g., 62330-62331, S2348) may be denied.

Background and Rationale

Open discectomy (OD) and microdiscectomy (MD) are surgical procedures to remove disc material compressing nerve roots; MD is typically performed through a smaller incision with microscope or magnification. Minimally invasive discectomy (MID) techniques aim to reduce tissue disruption by using percutaneous or endoscopic approaches, laser, coblation or tubular systems, but the evidence cited in this policy does not demonstrate a consistent advantage in functional or pain outcomes compared with standard OD/MD.

Definitions and Clinical Scales

inv-23: Microdiscectomy / Open discectomy (MD/OD) — definition

DefinitionSurgical removal of the portion of the intervertebral disc compressing the nerve root or spinal cord; microdiscectomy typically uses a smaller incision and microscope magnification

PurposePerformed to relieve nerve root compression causing radiculopathy or neurologic deficit

Technique notesMay include laminotomy or hemilaminectomy to visualize and remove disc fragment

inv-24: Minimally invasive discectomy (MID) — definition and techniques enumerated

DefinitionA group of less invasive techniques that use smaller incisions and indirect visualization to remove disc material

Enumerated techniquesPercutaneous manual nucleotomy, automated percutaneous lumbar discectomy (APLD/MILD), laser discectomy, endoscopic discectomy, microendoscopic discectomy, coblation nucleoplasty, tubular/trocar approaches, disc DeKompressor

Documentation Required

Required Clinical Documentation for Surgical Coverage

When requesting authorization for open discectomy or microdiscectomy, include complete clinical documentation to substantiate medical necessity. Documentation must demonstrate diagnosis, imaging confirmation, neurological findings, and prior conservative therapy.

Diagnosis of herniated lumbar disc and nerve root compression confirmed by imaging (e.g., MRI/CT).
Detailed neurologic exam notes documenting motor or sensory deficits (MRC motor scale scores when applicable).
Progress notes showing duration and response to conservative therapy and any inability to tolerate therapy.
If applicable, documentation of worsening weakness or progressive neurologic deficit.

Documentation Required

Documentation and Contractual Compliance

Providers must comply with contractual documentation and coverage requirements. This policy is proprietary to the Health Plan; unauthorized use is prohibited. When state Medicaid or Medicare NCDs/LCDs conflict with this policy, the applicable program rules take precedence.

Submit operative reports, imaging reports, and relevant office visit notes with prior authorization requests and claims.
For Medicaid members, follow state Medicaid coverage provisions where they differ from this policy.
For Medicare members, review applicable NCDs, LCDs, and Coverage Articles prior to applying policy criteria.

Note

Conservative Therapy Prerequisites

Prior to considering surgical intervention, members must have adequate trials of conservative therapy as defined in this policy. Failure to document required conservative management may render a request not medically necessary.

≥ four weeks of physical therapy or prescribed home exercise program (or documentation of inability to tolerate).
≥ four weeks of activity modification.
Either ≥ three weeks of NSAID or acetaminophen unless contraindicated/not tolerated, or an epidural steroid injection as appropriate.
