Ernest or Eagle's Syndrome (Stylomandibular Ligament Pain): Treatment with Radiofrequency Thermoneurolysis

Radiofrequency thermoneurolysis (RF ablation/neurolysis) for Ernest/Eagle's syndrome is considered experimental and investigational and is not covered. The policy cites insufficient evidence in peer‑reviewed literature (anecdotal reports lack rigor), notes no specific CPT/HCPCS code exists (code 64600 is referenced but not endorsed), and RF is also considered investigational for TMJ/TMD.

"No specific CPT/HCPCS code exists for radiofrequency thermoneurolysis for this indication (policy notes: "No specific code")."
