CMM-211: Spinal Cord and Dorsal Root Ganglion Stimulation

CMM-211 covers short-term trials (>48 hrs) and, if successful, permanent implantation of non-high-frequency dorsal column SCS (with HF10 only in limited circumstances) for FBSS with neuropathic leg pain, extremity-only CRPS/RSD, chronic critical limb ischemia, and chronic stable angina, while labeling HF SCS for other indications, DRG stimulation, peripheral nerve stimulation, burst/other generator modes, and certain replacements as experimental, investigational, or not medically necessary. Key requirements include failure of ≥6 months of physician‑supervised conservative therapy, behavioral‑health clearance, condition-specific objective diagnostic findings and specialty attestations (e.g., vascular surgeon for CLI, cardiologist for angina), demonstration of benefit from a short-term trial (generally ≥50% pain reduction for permanent implantation), and documented device malfunction criteria for replacements.
