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.

Overall coverage conclusion

Covered when ALL of the following are met:

Primary finding: There is insufficient evidence to determine the reliability or diagnostic accuracy of discography for discogenic pain and insufficient evidence that discography improves patient selection or surgical outcomes.

Evidence conclusion from Kaiser Permanente Medical Technology Assessment review

Kaiser Permanente's Medical Technology Assessment concluded that there is insufficient evidence to determine the reliability or diagnostic accuracy of provocative discography for identifying discogenic pain and insufficient evidence that discography improves patient selection or surgical outcomes. Consequently, the assessment does not support routine use of discography for management of lower back pain.

Provocative discography (lumbar, cervical, thoracic) is considered not medically necessary. The use of discography in the treatment of lower back pain does not meet Kaiser Permanente Medical Technology Assessment Criteria and is identified in this policy as not covered.

Provider Actions and Authorization

Denial Risk

Authorization / Not medically necessary codes

Discography services listed below are considered Not Medically Necessary by Kaiser Permanente and may be denied if provided without confirmed authorization. Verify prior authorization requirements for the member's specific plan using the Pre-authorization Code Check before scheduling or billing.

Not Medically Necessary codes: 62290, 62291, 62292, 72285, 72295
Codes may not be all-inclusive; deleted or out-of-effect codes may not be covered
To verify authorization requirements for a specific code by plan type, use the Pre-authorization Code Check

Note

Prior conservative and imaging considerations

Specialty society guidance recommends reserving provocative discography for select patients (e.g., when MRI/CT results are equivocal and surgical intervention is being considered) after prior conservative care and imaging have been completed. Consider noninvasive imaging (MRI or CT) and conservative treatment trials before discography.

Documentation Required

Procedure documentation elements

When performed, documentation must demonstrate use of fluoroscopic guidance, patient awake and cooperative, patient blinded to injection timing/level, concordant pain response documented (including VAS or pain thermometer ratings for each level), description of contrast distribution, and post-discogram CT when obtained. Include level(s) tested and any complications.

Denial Risk

Coverage denial risk

Because provocative discography is considered Not Medically Necessary per this policy, claims may be denied and prior authorization may be required. Confirm coverage and obtain any required authorizations prior to performing the procedure to reduce claim denial risk.

Prior Conservative Management and Imaging Requirements

Prior noninvasive imaging (MRI/CT) and consideration of conservative management before contemplating discography

Prior to considering provocative discography, ALL of the following must be documented:

Imaging and conservative management: Recent noninvasive imaging (MRI and/or CT) that is available for review and either demonstrates equivocal or inconsistent findings relative to the patient's symptoms or has been correlated with clinical evaluation; MRI is the morphological imaging study of choice.

Specialty guidelines recommend reserving discography for patients with equivocal or inconsistent MRI/other imaging findings and when surgical intervention is being considered.

Conservative treatment consideration: Documentation that appropriate conservative management has been attempted and considered (or that surgical intervention is being contemplated) such that invasive diagnostic testing like discography is being considered only to clarify indications for surgery.

Guideline-based recommendation to reserve discography for surgical candidates with unclear imaging correlation.

Patient counseling and procedural considerations: Acknowledgment of the invasive nature and potential risks of discography (including discitis and other complications) and that the patient has been informed; if performed, the procedure requires fluoroscopic/X-ray guidance and typically is done with the patient awake to record pain responses, often followed by post-discogram CT for further visualization.

Procedure documentation elements and complication profile to be recorded in the medical record.

Imaging Correlation

Note

Discography interpretation — correlate with MRI and consider CT

When interpreting discography, correlate findings with MRI and consider post‑discogram CT for better visualization of disc morphology.

Use MRI as the morphological imaging study of choice and correlate discography results with MRI findings.
Obtain post‑discogram CT when indicated to further assess disc abnormalities.

Background

Discography (discogram) is a provocative diagnostic procedure in which radio-opaque contrast is injected into the nucleus pulposus of an intervertebral disc under fluoroscopic/X-ray guidance while the patient is awake and able to report pain. The test is intended to reproduce the patient’s typical pain (pain concordance) and assess disc morphology; it is often followed by post-discogram CT for additional visualization. MRI and CT provide morphologic information but cannot by themselves confirm symptomatic discogenic pain.

Definitions

Discography (discogram) definition

TermDiscography (discogram)

Key procedural elementsInjection performed with 22–25 gauge needle; patient awake and cooperative; patient blinded to time/level of injection; pain rated on a visual analogue scale (VAS) or pain thermometer.

Imaging follow-upPost‑discogram CT is often performed for more thorough visualization and assessment of disc abnormalities.

Clinical intentUsed as a provocative test to attempt symptom‑pathology correlation for suspected discogenic pain rather than as a purely morphologic imaging study.

Discogenic pain definition

TermDiscogenic pain

DefinitionLow back pain presumed to originate from an intervertebral disc; there is no clinical diagnostic gold standard and imaging (MRI/CT) can detect disc degeneration morphologically but cannot definitively confirm that a particular disc is the symptomatic pain generator.

Diagnostic limitationSurgical exposure or morphologic imaging cannot with certainty identify the symptomatic disc; current evidence is insufficient to reliably determine discogenic pain using available tests.

Relation to discographyDiscography is used as a provocative test intended to reproduce familiar pain and help implicate a disc as the source, but its reliability for diagnosing discogenic pain is uncertain.

Not Covered Services

Provocative discography performed to diagnose or guide treatment of low back pain is not covered under this policy. Because the Medical Technology Assessment found insufficient evidence of diagnostic reliability and beneficial impact on outcomes, services for discography may be denied and associated CPT/HCPCS codes are identified as not medically necessary.
