While most infusion claims are billed with HCPCS per diem S-codes, others need to be billed using supply and equipment codes. In this reference are the supply kit and equipment rental codes used by therapy when billing using supply kits format (versus billing the per diem codes). Supply kits are often used when instructed to bill using “Medicare billing rules.” When it is not defined at the payer level, it is recommended that you use the per diem “S” codes as a best practice.
