Billing and Coding: Nerve Blocks for Peripheral Neuropathy

Medicare coverage for peripheral nerve blocks for peripheral neuropathy requires documentation that the service is medically necessary and must include appropriate diagnosis coding and signed clinical records. Multiple injections per day on multiple days per week—especially for multiple neuropathies or neuropathies due to systemic disease—are considered not medically necessary and non-covered; ABN usage and specific GA/GX/GY/GZ modifiers must be applied as directed, with Part A claims requiring occurrence code 32 when an ABN is used.

"Peripheral nerve injection/nerve block for peripheral neuropathy may be covered when the medical record documents that the service is medically necessary for the patient's specific condition."
