CIDP and PI Access and Billing Codes
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.

HCPCS Billing Codes11,12
The following HCPCS codes describe supplies (including drugs) rendered by the billing provider. CMS publishes and maintains the HCPCS code set.
These codes are entered to paper claim form CMS-1500 in Field 24; or to electronic claim form ASC 837P in Loop 2400, Segment SV101-2, with the Qualifier "HC" entered to Segment SV101-1, unless otherwise directed by the payer.
|Hizentra: Immune Globulin Subcutaneous (Human), 20% liquid12|
|J1559||Injection, immune globulin (Hizentra), 100 mg|
Certain payers may require the entry of NDC information to the claim form, as directed by the payer.
|Ready-to-Use Hizentra Vial Sizes|
|Grams Protein||Fill Size||NDC Number to Use on All Claim Forms|
|1 g||5 mL||44206-0451-01|
|2 g||10 mL||44206-0452-02|

If the billing provider performs administration services in conjunction with a patient's infusion, the following administration codes may be used to bill for this service if the service meets the requirements of the code description.
|CPT Code 11||Description|
|96369||Subcutaneous injection for therapy or prophylaxis; initial, up to 1 hour, including pump setup and establishment of subcutaneous infusion site(s)|
|96370||Each additional hour|
|96371||Additional pump setup with establishment of new subcutaneous infusion site(s)|
Billing for Medicare DME MACs12
The Medicare benefit for patients with primary immunodeficiency 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).
For further information on CIDP patients, please contact IgIQ.
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|
|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. The following three codes are necessary for billing Hizentra. We recommend that you include them during the prior authorization process.
|External Infusion Pump Supplies|
|K0552||Supplies for external drug infusion pump, syringe-type cartridge, sterile, each|
|A4221||Supplies for maintenance of drug infusion catheter, per week|
|A4222||Infusion supplies for external drug infusion pump, per cassette or bag|
All 3 codes are needed to bill for infusion pump supplies.
|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. 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.
