COVERAGE TOPIC
Facet joint interventions, including diagnostic and therapeutic injections as well as neurolytic destruction, for cervical/thoracic and lumbar/sacral spine regions with image guidance are addressed under this policy.

MEDICAL NECESSITY SUMMARY
Facet joint procedures must be performed based on documented clinical evaluation and relevant history indicating facet-mediated pain. Diagnostic injections require use of appropriate ICD-10 diagnosis codes and adherence to allowed spinal regions and levels. Unilateral or bilateral injections count as one level per joint, with bilateral procedures reported using modifier -50. Therapeutic injections require documentation if radiofrequency ablation (RFA) is not a suitable option. Neurolytic destruction codes are reported per joint, not per nerve.

DOCUMENTATION ELEMENTS TO SUPPORT
– Assessment relating to patient’s pain complaint for the visit
– Relevant medical history
– Results of pertinent diagnostic tests or prior procedures
– Signed and dated office visit or operative notes
– Rationale why patient is not a candidate for RFA if applicable
– Documentation supporting medical necessity for use of sedation (if used during RFA or cyst aspiration/rupture)

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

CPT/HCPCS CONTEXT
– 64490-64492 (Paravertebral facet injections, cervical/thoracic, single and additional levels with image guidance)
– 64493-64495 (Paravertebral facet injections, lumbar/sacral, single and additional levels with image guidance)
– 64633-64636 (Neurolytic destruction by thermal agent of facet joint nerves, cervical/thoracic and lumbar/sacral)
– Bilateral procedures require modifier -50
– Ultrasound guidance procedures (codes 0213T-0218T) are not covered
– KX modifier appended for diagnostic injections, mostly initial two injections

NOT COVERED / CAUTIONS
– Non-thermal facet joint denervation procedures (e.g., chemical or pulsed RF reported with 64999) are non-covered
– Moderate or deep sedation, general anesthesia, or monitored anesthesia care (MAC) during facet injections are generally not medically necessary
– Use of biologicals or unauthorized substances for facet joint injection will cause claim denial
– Ultrasound-guided facet injections are not covered
– Use of sedation for RFA or cyst aspiration requires clear clinical justification to avoid denials
– Not clearly stated in source: Specific frequency limitations (refer to LCD L38801)

SUGGESTED CLINICAL COPY
Patient presents with [region]-region facet-mediated pain, supported by relevant history and diagnostic evaluation consistent with facet joint pathology. Diagnostic/therapeutic paravertebral facet joint injection performed at [specified level(s)] with fluoroscopic or CT image guidance. Procedure documented as unilateral/bilateral and levels counted by facet joint involvement. Documentation supports lack of candidacy for RFA for therapeutic injections. Sedation was not used / sedation used with documented medical necessity (if applicable). Plan includes follow-up assessment and possible additional interventions per clinical response.

SUGGESTED ROI / RECORDS TO REQUEST
– Office visit or consultation notes describing patient pain complaint and physical exam
– Relevant imaging or diagnostic test results
– Prior treatment records and response including prior facet injections or RFA
– Operative or procedure notes for the facet intervention
– Documentation supporting medical necessity of sedation if used
– Any referral or ordering physician documentation per billing rules
