Regional or local nerve blocks performed as part of an operative procedure (e.g., adjunct to or sole means of regional/local anesthesia for the procedure) are not affected by this non-coverage policy and may be billed as anesthesia for the operative procedure.
Regional or local nerve blocks performed as an adjunct to, or as the sole means of, regional/local anesthesia for an operative procedure are not affected by this noncoverage policy (i.e., such intraoperative regional/local anesthesia is allowed).
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.
Peripheral nerve blocks are covered when they meet the reasonable and necessary requirements specified in LCD L33933.
Peripheral nerve block is reasonable when the patient's pain appears due to a classic mononeuritis but neuro-diagnostic studies fail to provide a structural explanation.
