You need to pull the local coverage determination policy that could potentially be titled Local Coverage Determination (LCD):
Nerve Blocks for Peripheral Neuropathy (L34673)
If it is similar to the below LCD from WPS Medicare J5 you will see at the bottom of the policy it states
Peripheral nerve injections will not be allowed unless medical records are reviewed and the services are approved during the redetermination process.
So you have write an appeal and it has demonstrate that the nerve block was not for "the treatment of multiple neuropathies or peripheral neuropathies caused by underlying systemic diseases" and provide the medical records. They will review it paid it if is not due to "underlying systemic diseases"
Coverage Indications, Limitations, and/or Medical Necessity
Nerve blocks cause the temporary interruption of conduction of impulses in peripheral nerves or nerve trunks by the injection of local anesthetic solutions.
The use of nerve blocks or injections for the treatment of multiple neuropathies or peripheral neuropathies caused by underlying systemic diseases is not considered medically necessary. Medical management using systemic medications is clinically indicated for the treatment of these conditions.
Limitations
The use of nerve blocks with or without the use of electrostimulation, and the use of electrostimulation alone for the treatment of multiple neuropathies or peripheral neuropathies caused by underlying systemic diseases is not considered medically reasonable and necessary.
At present, the literature and scientific evidence supporting the use of peripheral nerve blocks with or without the use of electrostimulation/electromagnetic stimulation, and the use of electrostimulation/ electromagnetic stimulation alone for neuropathies or peripheral neuropathies caused by underlying systemic diseases, is insufficient to warrant coverage. These procedures are considered investigational and are not eligible for coverage for the treatment of neuropathies or peripheral neuropathies caused by underlying systemic diseases.
The use of ultrasound guidance in conjunction with these non -covered injections is also considered not medically necessary and will result in denial.
Subcutaneous injections do not involve the structures described by CPT code 64450, direct injection into other peripheral nerves, but rather the injection of tissue surrounding a specific focus. These therapies are not to be coded using CPT code 64450. This code addresses the additional work of an injection of an anesthetic agent (nerve block), into relatively more difficult peripheral nerves, rather than that involved in an injection of relatively easily localized areas.

Contractors may specify Bill Types to help providers identify those Bill Types typically used to report this service. Absence of a Bill Type does not guarantee that the policy does not apply to that Bill Type. Complete absence of all Bill Types indicates that coverage is not influenced by Bill Type and the policy should be assumed to apply equally to all claims.

Revenue Codes:
Contractors may specify Revenue Codes to help providers identify those Revenue Codes typically used to report this service. In most instances Revenue Codes are purely advisory; unless specified in the policy services reported under other Revenue Codes are equally subject to this coverage determination. Complete absence of all Revenue Codes indicates that coverage is not influenced by Revenue Code and the policy should be assumed to apply equally to all Revenue Codes.

Associated Information
Documentation Requirements
1. All documentation must be maintained in the patient?s medical record and available to the contractor upon request.
2. Every page of the record must be legible and include appropriate patient identification information (e.g., complete name, dates of service(s)). The record must include the physician or non-physician practitioner responsible for and providing the care to the patient.
3. The submitted medical record should support the use of the selected diagnosis code(s). The submitted CPT/HCPCS code should describe the service performed.
Utilization Guidelines
Treatment protocols utilizing multiple injections per day on multiple days per week for the treatment of multiple neuropathies or peripheral neuropathies caused by underlying systemic diseases are not considered medically necessary.
Peripheral nerve injections will not be allowed unless medical records are reviewed and the services are approved during the redetermination process.
