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

CPT codes 64400-64530 for peripheral nerve blocks may be reported on the date of surgery when performed for postoperative pain management only if the operative anesthesia is general anesthesia, subarachnoid injection, or epidural injection and the adequacy of intraoperative anesthesia is not dependent on the peripheral nerve block.
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.
Lab-developed tests for inherited cancer syndromes in patients with cancer as described in Local Coverage Determination (LCD) L39040 are the services addressed by this billing/coding guidance.
ClonoSeq (NGS-based MRD test) is covered for patients with acute lymphoblastic leukemia (ALL).
ClonoSeq (NGS-based MRD test) is covered for patients with multiple myeloma (MM).
ClonoSeq (NGS-based MRD test) is covered for patients with chronic lymphocytic leukemia (CLL).

A claim submitted without a valid ICD-10-CM diagnosis code will be returned as an incomplete claim under Section 1833(e) and the diagnosis code(s) must best describe the patient's condition for which the service was performed.

For diagnostic tests, report the test result if known; if not available, report the symptoms that prompted the test.
