CMS SOURCE

COVERAGE TOPIC
CMS covers cervical/thoracic and lumbar/sacral paravertebral facet joint interventions for pain management, including diagnostic and therapeutic injections and neurolytic destruction with imaging guidance. Coverage and coding are subject to LCD criteria, proper coding, and medical necessity.

MEDICAL NECESSITY SUMMARY
Facet joint interventions are considered reasonable and necessary when performed for evaluation or treatment of pain related to the cervical, thoracic, lumbar, or sacral facet joints using image guidance (fluoroscopy or CT). Diagnostic injections require proper indication and documentation of response; therapeutic injections require justification if the patient is not eligible for radiofrequency ablation (RFA). Neurolytic destruction (e.g., RFA) codes apply per joint, not per nerve, and bilateral procedures must be properly documented with modifiers. Ultrasound-guided and non-thermal denervation procedures are not covered under the standard CPT codes.

DOCUMENTATION ELEMENTS TO SUPPORT
– Assessment related to patient’s pain complaint during the visit
– Relevant medical history supporting the intervention
– Pertinent diagnostic test or prior procedural results
– Signed and dated office visit notes or operative reports
– Justification if patient is not a candidate for RFA (for therapeutic injections)
– Medical necessity documentation for use of moderate/deep sedation or MAC if applicable (rare)

COMMON SUPPORTING ICD-10 THEMES
– M47.812–M47.817: Spondylosis without myelopathy or radiculopathy (cervical/lumbar regions)
– M47.892–M47.897: Other spondylosis (various spinal regions)
– M48.12–M48.17: Ankylosing hyperostosis [Forestier] (spinal regions)
– M53.82–M53.87: Other specified dorsopathies (spinal regions)

CPT/HCPCS CONTEXT
– 64490–64495: Diagnostic or therapeutic paravertebral facet joint injections with fluoroscopy or CT guidance (cervical/thoracic and lumbar/sacral levels)
– 64633–64636: Neurolytic destruction (e.g., RFA) of facet joint nerves with imaging guidance, reported per joint
– Modifier -50 used to denote bilateral interventions for injections and destructions
– Ultrasound-guided facet injections (codes 0213T–0218T) are not covered
– Non-thermal denervation should not be reported with codes 64633–64636 and is non-covered under CPT code 64999 when used for facet denervation

NOT COVERED / CAUTIONS
– Use of Moderate or Deep Sedation, General Anesthesia, or MAC during facet injections is not generally covered unless medically necessary and documented for RFA or cyst aspiration/rupture
– Ultrasound-guided facet joint injections are not covered
– Non-thermal facet joint denervation is non-covered when reported under standard neurolytic codes
– Injection of biological agents or substances not designated for facet joints will result in claim denial per Benefit Policy Manual
– Initial diagnostic injections with KX modifier – must be justified; aberrant use may trigger medical review
– Number of levels counted by facet joints, not nerve branches

SUGGESTED CLINICAL COPY
Patient presents with pain localized to the [cervical/thoracic/lumbar/sacral] region consistent with facet joint syndrome. After clinical assessment and review of prior imaging and test results, image-guided paravertebral facet joint injection(s) was performed for diagnostic/therapeutic purposes. Patient either showed a positive response to diagnostic injections or was documented as unsuitable for radiofrequency ablation. Relevant medical history and examination findings support the medical necessity of this procedure. Documentation includes signed operative note and applicable ICD-10 diagnosis codes describing the spinal condition targeted.

SUGGESTED ROI / RECORDS TO REQUEST
– Previous spinal imaging studies (MRI, CT, X-rays)
– Prior diagnostic/therapeutic injections and response documentation
– Detailed clinical notes on pain history and physical exam findings
– Any contraindication or non-candidacy documentation for RFA
– Signed procedure notes and anesthesia records if sedation was used
– Relevant laboratory or diagnostic test results supporting diagnosis
