The document is updated quarterly and includes codes for various medical procedures, tests, and supplies that are covered by Medicare Part B. The payment rates listed in Addendum B are used to reimburse healthcare providers for the services they provide to Medicare beneficiaries.

The HCPCS codes in Addendum B are organized by type of service, with separate sections for Durable Medical Equipment, Prosthetics, Orthotics, and Supplies (DMEPOS), drugs, laboratory tests, and other services. Each code is listed with a description of the service or item it represents, along with the payment rate for that code.

Healthcare providers and suppliers who bill Medicare for Part B services must use the codes and payment rates listed in Addendum B to ensure they are properly reimbursed. The document is an important resource for healthcare providers and suppliers who participate in the Medicare program.
