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.

Open SIJ fusion criteria

Indications (at least one): Patient has at least one of: post-traumatic SIJ injury (e.g., following pelvic ring fracture); adjunctive treatment for SIJ infection (e.g., osteomyelitis, pyogenic sacroiliitis)/sepsis; management of sacral tumor (e.g., partial sacrectomy); part of a multisegmental long fusion construct for correction of spinal deformity (e.g., idiopathic or neuromuscular scoliosis); prior percutaneous SIJ fusion has failed.
Imaging: Recent (within 6 months) plain x-rays and/or cross-sectional imaging (CT or MRI) demonstrate localized SIJ pathology.

Operational note: Prior authorization requires documentation that all criteria above are met, including the specific indication and recent imaging.

Percutaneous SIJ Fusion/Stabilization - Medical Necessity

CareSource considers percutaneous SIJ fusion/stabilization medically necessary when ALL the following are met:

Percutaneous SIJ fusion criteria

Symptoms and exam: Presence of non-radiating pain caudal to L5 localized over the posterior SIJ consistent with SIJ pain; SIJ pain >= 5/10; localized posterior SIJ tenderness without similar severity elsewhere and no other obvious pain source; positive thigh thrust OR compression test; positive response to at least two of Gaenslen's, distraction, or Patrick's tests.
Conservative therapy failure: Documentation of at least 6 months of active conservative therapy within the past 12 months OR documented inability to complete active conservative therapy due to contraindication, increased pain, or intolerance; AND documentation of at least 6 months of inactive conservative therapy within the past 12 months.
Diagnostic confirmation: At least two image-guided, contrast-enhanced intra-articular SIJ blocks on separate occasions with >= 50% reduction in pain for the expected duration of the anesthetic used.
Imaging exclusions: Imaging (plain radiographs and CT or MRI) of the SIJ excludes destructive lesions (e.g., tumor, infection) or inflammatory arthropathy not addressable by percutaneous fusion; ipsilateral hip radiographs to rule out osteoarthritis; lumbar spine CT/MRI to rule out neural compression or other degenerative causes.
Behavioral exclusions: Exclusion of generalized pain behavior or generalized pain disorders (e.g., somatoform disorder, fibromyalgia) as the primary etiology of pain.
Therapeutic injections: Failure of a trial of at least two therapeutic intra-articular SIJ injections (e.g., corticosteroid injection).

Operational note: Prior authorization requires documentation of history, physical exam provocation tests, imaging that excludes alternate causes, conservative therapy details, and the two diagnostic SIJ blocks showing >=50% pain relief.

Open sacroiliac joint (SIJ) fusion is considered not medically necessary for any indication not specifically listed in the policy. Examples of such noncovered indications include, but are not limited to: mechanical low back syndrome, sacroiliac joint syndrome, degenerative sacroiliac joint, or when there is the presence of neural compression on CT or MRI that correlates with the member’s symptoms or identifies a more likely source of pain (eg, radicular pain).

Percutaneous SIJ fusion/stabilization is considered not medically necessary for indications outside those specifically described in the policy. Notable exclusions include systemic arthropathy (for example, ankylosing spondylitis or rheumatoid arthritis), generalized pain behavior or disorders (eg, somatoform disorder or fibromyalgia), and structural or acute conditions such as infection, tumor, fracture, or acute traumatic SIJ instability. Procedures are also not covered when there is neural compression on MRI or CT that correlates with the patient’s symptoms or indicates another more likely pain source.

Diagnostic and Severity Criteria

inv-07: Diagnostic SIJ block response

Diagnostic block response required>= 50% pain reduction on two separate image-guided, contrast-enhanced intra-articular SIJ blocks (performed on separate occasions) for the expected duration of the anesthetic.

Number of blocksTwo separate image-guided intra-articular SIJ blocks are required.

Guidance on techniqueBlocks must be image-guided and contrast-enhanced.

Timing requirementBlocks should be performed on separate occasions to confirm reproducible pain reduction.

inv-08: Pain severity

Pain severity thresholdSIJ pain must register at least a 5 on a 0–10 numeric pain scale.

Location requirementPain must be non-radiating and localized caudal to L5 over the posterior SIJ.

Exam correlationLocalized posterior SIJ tenderness without similar severity elsewhere is required alongside the pain score.

Authorization and Documentation Requirements

Prior Authorization

Prior Authorization Required

Prior authorization is required. Documentation must demonstrate that all medical necessity criteria are met, including appropriate imaging and completion or inability to complete conservative therapy.

Prior authorization required before percutaneous SIJ fusion

Documentation Required

Medical Record Documentation Required

Medical record documentation must include evidence of at least 6 months of active conservative therapy within the past 12 months OR documentation of inability to complete active conservative therapy due to contraindication, increased pain, or intolerance. In addition, document at least 6 months of inactive conservative therapy within the past 12 months when applicable.

Document ≥6 months of active conservative therapy within the past 12 months OR inability to complete active conservative therapy (contraindication, increased pain, or intolerance)
Document ≥6 months of inactive conservative therapy within the past 12 months (when applicable)

Denial Risk

Failure of Conservative Therapy Required

Failure of conservative therapy is required prior to approval. The record must show failure of conservative management as defined by the policy (see documentation requirements above) before percutaneous SIJ fusion will be considered medically necessary.

Failure of conservative therapy required: evidence per policy (active and inactive therapy durations or documented inability to complete)
At least two therapeutic intra-articular SIJ injections must have failed

Denial Risk

Percutaneous SIJ Fusion — Not Medically Necessary for Other Indications

Percutaneous SIJ fusion is not medically necessary for indications not outlined in this policy, including but not limited to systemic arthropathy (eg, ankylosing spondylitis, rheumatoid arthritis), generalized pain disorders (eg, fibromyalgia, somatoform disorder), infection, tumor, fracture, acute traumatic SIJ instability, or neural compression correlating with the patient's symptoms.

Percutaneous SIJ fusion is NOT medically necessary for indications not specified in policy: systemic arthropathy, generalized pain behavior/disorders, infection, tumor, fracture, acute traumatic instability, neural compression

Conservative Therapy Definition

inv-15: Conservative Therapy definition

DefinitionConservative Therapy: a multimodality plan of care including both active and inactive therapies.

Active therapies (examples)Physical therapy, occupational therapy, physician‑supervised home exercise program (HEP), and/or chiropractic care; HEP is a 6‑week program requiring an exercise prescription and documented follow‑up or documented inability to complete for physical reasons.

Inactive (passive) therapies (examples)Rest, ice, heat, medical devices, transcutaneous electrical nerve stimulation (TENS), and pharmacotherapy (prescription or OTC).

Documentation requirementsUse, frequency, duration, and start dates for modalities like TENS and HEP must be documented in the medical record to count toward conservative therapy.
