Pain procedure classifications to guide infection control measures
| A (Musculoskeletal and PNBs) | B (Neuraxial and paravertebral procedures, sympathetic blocks) | C (Neuromodulation, intradiscal, and minimally invasive procedures) | D (Surgical-type interventional pain procedures) |
| Trigger point injections | Epidural corticosteroid injections (interlaminar and transforaminal) | Intradiscal procedures | Peripheral nerve stimulation implants/replacements/revisions |
| Musculoskeletal and joint injections | Facet joint and medial branch nerve block injections and radiofrequency ablation | Peripheral nerve stimulation trials | Spinal cord stimulation implants/replacements/revisions |
| Single-injection PNBs | Sacroiliac joint injections and sacral lateral branch blocks and radiofrequency ablation | Spinal cord stimulation trials | Dorsal root ganglion stimulation implants/replacements/revisions |
| Paravertebral blocks | Dorsal root ganglion stimulation trials | Interspinous spacer/fusion implants | |
| Sympathetic blocks (stellate, splanchnic, celiac, lumbar, superior hypogastric, ganglion impar) | Vertebral augmentation (vertebroplasty and kyphoplasty) | Intrathecal catheter and pump implants/replacements/revisions | |
| Single-injection intrathecal drug trials | Percutaneous image-guided lumbar decompression | Sacroiliac joint fusion | |
| Intrathecal pump refills | Basivertebral nerve ablation | ||
| Indwelling catheters ≤4 days (peripheral, epidural, intrathecal) | Indwelling catheters >4 days (peripheral, epidural, intrathecal) |
PNB, peripheral nerve block.
