Prior Authorization

No Prior Auth Required

Code is covered without prior authorization (high confidence)

Documentation Required

The performing provider must maintain medical record documentation that clearly supports the medical necessity of the billed service and include that documentation in the patient's record for review upon request.
Documentation should state whether the block was diagnostic or therapeutic, include pre- and post-procedure evaluations, and document patient education and the assessment of procedural outcome.
Documentation must support coverage criteria in the LCD 'Indications and Limitations of Coverage and/or Medical Necessity' section and the provider should document why services cannot be rendered by the surgeon when applicable.
For services requiring a referring/ordering physician, the referring/ordering physician's name and NPI must be reported on the claim.

Key Coverage Criteria

Peripheral nerve block services that are separate, medically necessary services which cannot be rendered by the surgeon may be reported if the surgeon documents the reason for referral and the additional services are justified in the medical record.
