Claims and documentation requirements for CPNB are governed by and must follow the Local Coverage Determination L37641 referenced by this guideline.
Medical records must clearly document medical necessity for each test and include the reason for referral and a clear diagnostic impression.
Data gathered during NCS should be available showing actual numeric results (latency, amplitude, etc.), preferably in tabular format.
In cases of review, provide a hard copy of waveforms or a complete written report with interpretation upon request.

No specific coverage indications are stated in this billing/coding guideline; refer to Local Coverage Determination L37641 for covered indications for continuous peripheral nerve blocks (CPNB).
NC-stat testing (CPT 95905) is allowed when the beneficiary has a high pre-test or prior probability of Carpal Tunnel Syndrome (CTS), limited to one service per arm.
Use CPT 95870 for sampling muscles other than the paraspinals associated with the extremities that have been tested.
Epiduroscopy / epidural lysis of adhesions: proposed for diagnosis/treatment of intractable LBP (including failed back surgery syndrome) by visualizing and lysing adhesions and injecting medications (insufficient high-quality evidence to support routine clinical use).
Kyphoplasty (balloon-assisted vertebroplasty): restore bone height for painful osteoporotic compression fractures (OVCFs); NICE and other assessments note kyphoplasty may be a reasonable alternative to vertebroplasty for recent fractures.
Sacropasty: injection of PMMA into sacrum for sacral insufficiency fractures (SIFs) in osteoporotic patients to stabilize fracture and relieve pain (developing indication).
