Diagnostic and billing codes for Hizentra therapy

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 Connect, the comprehensive resource center for CSL Behring's Immune globulin (lg) therapies, is there to answer any additional questions you might have about diagnostic or billing codes for Hizentra.

G0069	Subcutaneous immunotherapy and other certain subcutaneous infusion drugs, subsequent encounter
Providers must be a qualified HIT supplier to bill for professional services. Section 1861(iii)(3)(C) of the Act defines a “home infusion drug” as a parenteral drug or biological administered intravenously, or subcutaneously for an administration period of 15 minutes or more, in the home of an individual through a pump that is an item of durable medical equipment (as defined in section 1861(n) of the Act). The professional visit G-code claim will recycle three times (with a 30-day look back period) for a total of 15 business days. After 15 business days, if no J-code claim is found in claims history, the G-code claim will be denied.

Billing for Medicare DME MACs¹²

The Medicare benefit for patients with primary immune deficiency or chronic inflammatory demyelinating polyneuropathy for subcutaneous immune globulin administered by DME MACs applies only to those products that are specifically labeled as subcutaneous administration products. Intravenous immune globulin products administered via the subcutaneous route are not covered by Medicare DME MACs (refer to Local Coverage Decision for External Pumps, effective 2/4/2011). Billing for External Pumps and Supplies When the billing provider furnishes an external infusion pump for patient use, the following code may be used to bill for the pump if it meets the requirements of the code description.
External Infusion Pump
HCPCS Code	Description
E0779	Ambulatory infusion pump, mechanical, reusable, for infusion 8 hours or greater
E0779 is the only reimbursable pump code for infusion of Hizentra under Medicare Part B.* 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.

Professional Services for Drug Infusion
G0069	Professional services for the administration of subcutaneous immunotherapy for each infusion drug administration calendar day in the individual's home, each 15 minutes
External Infusion Pump Supplies^*
K0552	Supplies for external non-insulin drug infusion pump, syringe type cartridge, sterile, each
A4221	Supplies for maintenance of non-insulin drug infusion catheter, per week (list drugs separately)
A4222	Infusion supplies for external drug infusion pump, per cassette or bag (list drugs separately)
*For E0779 and K0455 pumps, either A4222 or K0552 may be billed, but not both.
Modifier -JB for Medicare Billing
Medicare requires the addition of Modifier -JB (administered subcutaneously) to the HCPCS code for Hizentra (J1559) to confirm subcutaneous administration. Example: J1559-JB. Commercial and Medicaid plans may require the use of the JB modifier. If required, 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. Always check with the plan to see if the modifier code is required.
