Documentation Required
- All documentation must be maintained in the patient's medical record, be legible, include patient identifiers and dates of service, and be made available to the contractor upon request.
- The medical record must include the legible signature of the physician or non-physician practitioner responsible for the care and the submitted records must support the selected ICD-10-CM and CPT/HCPCS codes.
- Procedural reports for SNRBs and TFESIs must document indications, medical necessity, and baseline pain score; SNRBs must also document percent pain relief achieved immediately after the injection.
- Fluoroscopic/contrast films documenting final needle position and contrast flow (minimum two views) should be retained and made available upon request.
Key Coverage Criteria
- Epidural steroid injections (ESIs) for pain management are covered when reasonable and necessary per Local Coverage Determination L33906.
- Epidural injection CPT codes 62321, 62323, 64479, 64480, 64483 or 64484 used for postoperative acute post-thoracotomy pain (G89.12) or other acute postprocedural pain (G89.18) are exempt from the LCD diagnosis-code restrictions.
- Epidural injection CPT 62323 used as part of an implantable infusion pump trial for severe spasticity is adjudicated under NCD 280.14 and is exempt from the diagnosis-code restrictions in this article.
- Epidural injection CPT 62323 used for cerebrospinal fluid flow imaging (cisternography CPT 78630) is exempt from the diagnosis-code restrictions and should be billed on the same claim.
- Diagnostic selective nerve root blocks (DSNRBs) are coded identically to epidural injections and when performed on a transforaminal level (TFESI CPT 64479, 64480, 64483, 64484) the -KX modifier must be appended to distinguish DSNRB from therapeutic epidural injection.
- Nerve conduction studies (NCS) without needle EMG (NEMG) are allowed for individuals being evaluated for carpal tunnel syndrome or tarsal tunnel syndrome when one of the following ICD-10-CM codes is reported: G56.01, G56.02, G56.03, G56.11, G56.12, G56.13, G56.21, G56.22, G56.23, G57.51, G57.52, or G57.53.
