Effective with date of service Oct. 4, 2019, the Medicaid and NC Health Choice programs cover immune globulin subcutaneous, human – klhw 20% solution (Xembify®) for use in the Physician Administered Drug Program (PADP) when billed with HCPCS code J3590 - Unclassified biologics.
It is available as a solution containing 0.2 g/mL (200 mg/mL; 20%) protein solution for subcutaneous infusion. Xembify® is indicated for treatment of Primary Humoral Immunodeficiency (PI) in patients two years of age and older.
Recommended Dose (see full prescribing information for details):
For patients switching from immune globulin intravenous (human), 10% (IVIG) to Xembify®:
- Calculate the dose by using a dose adjustment factor (1.37)
- Weekly: Begin Xembify® one week after last IVIG infusion
- Establish initial weekly dose by converting the monthly (or every 3 weeks) IVIG dose into an equivalent weekly dose and increasing it using a dose adjustment factor (1.37). Initial weekly dose (grams) = [Prior IVIG dose (in grams) × 1.37 / Number of weeks between IVIG doses]
- Frequent dosing (2-7 times per week): Divide the calculated weekly dose by the desired number of times per week
For patients switching from immune globulin subcutaneous (human) treatment (IGSC):
- Weekly dose (grams) should be the same as the weekly dose of prior IGSC treatment (grams)
