The patient's medical record must contain documentation that fully supports medical necessity for services included in the related LCD, including relevant medical history, physical examination, and results of pertinent diagnostic tests or procedures.
Include a treatment prescription that defines treatment goals and specific dose-volume parameters for the target and nearby critical structures, and details of beam delivery such as method of beam modulation, field arrangement, and expected positional and range uncertainties.
Include a physician-signed treatment plan that meets the prescribed dose-volume parameters for the clinical target volume (CTV) and surrounding organs at risk (OARs) accounting for expected uncertainties.
Describe the target setup verification methodology, including patient positioning, immobilization, and use of image guidance.

Proton beam therapy is covered when the service meets the medical necessity criteria specified in the related Local Coverage Determination (LCD) and those criteria are documented in the medical record.
Nerve conduction studies (NCS) without needle EMG (NEMG) are allowed for individuals being evaluated for carpal tunnel syndrome or tarsal tunnel syndrome when one of the following ICD-10-CM codes is reported: G56.01, G56.02, G56.03, G56.11, G56.12, G56.13, G56.21, G56.22, G56.23, G57.51, G57.52, or G57.53.
NCS without NEMG is allowed for individuals with significant lymphedema in the affected extremity when ICD-10-CM code I89.0 is reported in addition to the primary diagnosis.
NCS without NEMG is allowed for individuals treated with anticoagulants when ICD-10-CM code Z79.01 or Z79.02 is reported in addition to the primary diagnosis.
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.
