Diagnostic and Billing Codes for Hizentra Therapy

Medicare, Medicaid, and most insurers cover Hizentra for the treatment of patients with primary immunodeficiency disease. All codes provided here are for informational purposes and are not an exhaustive list. The CPT, HCPCS, and ICD-10-CM codes provided are based on AMA or CMS guidelines. The treating physician is solely responsible for diagnosis coding and determination of the appropriate ICD-10-CM codes that describe the patient's condition and are supported by the medical record. The billing party is solely responsible for coding of services (eg, CPT Coding). Because government and other third-party payer coding requirements change periodically, please verify current coding requirements directly with the payer being billed.

Hizentra is covered as a Medicare Part B benefit with claims considered for payment by the four regional Durable Medical Equipment Medicare Administrative Contractors (DME MACs). Medicaid coverage policy varies by state. Coverage by other payers varies by payer and provider contract.

External Infusion Pump
HCPCS Code Description
E0779 Ambulatory infusion pump, mechanical, reusable, for infusion 8 hours or greater

Only an E0779 infusion pump is covered by Medicare for the administration of Hizentra.

Other pump codes may be used to bill other payers, depending on the pump that is used and the payer's pump coverage policy. The codes below are not covered by Medicare. Other pump codes may include:

E0781 Ambulatory infusion pump, single or multiple channels, electric or battery operated, with administrative equipment, worn by patient
E0791 Parenteral infusion pump, stationary, single or multichannel

When the billing provider furnishes supplies for the patient's use with the external infusion pump, the following codes may be appropriate for the supplies if they meet the requirements of the code description and payer coverage policies.

Modifier -JB should also be added to the HCPCS code for the covered infusion pump (E0779) following the modifier that indicates whether the pump is being rented (RR) or purchased (NU). Example: E0779-RR-JB or E0779-NU-JB.
