Work With Your Doctor to Get Xembify (Immune Globulin, SC) Approved by Humana in North Carolina

Quick Answer: Getting Xembify Approved by Humana in North Carolina

Xembify requires prior authorization from Humana with documented primary immunodeficiency diagnosis and lab evidence (low IgG levels, recurrent infections). Your doctor must submit clinical documentation including infection history, immunoglobulin levels, and prior therapy trials. Start by scheduling a visit with your immunologist or primary care provider to review your case and gather required documentation. If denied, you have 65 days to appeal internally, then 120 days for external review through North Carolina's Smart NC program. The fastest path: work closely with your provider's office to submit complete documentation upfront.

Set Your Goal: Understanding Approval Requirements

Your partnership with your healthcare provider centers on one clear objective: demonstrating medical necessity for Xembify through documented evidence of primary immunodeficiency.

Humana's Core Requirements:

  • Confirmed primary humoral immunodeficiency diagnosis with ICD-10 code
  • Laboratory evidence of immunoglobulin deficiency (typically IgG levels more than 2 standard deviations below age-adjusted reference range)
  • Documentation of recurrent infections requiring antibiotic therapy
  • Evidence of inadequate response to vaccines or protective antibody levels

Counterforce Health helps patients navigate exactly these requirements by analyzing denial letters and plan policies to create targeted, evidence-backed appeals that align with each payer's specific criteria.

Tip: Humana typically approves Xembify for 12 months when criteria are met, with quantity limits applied per FDA labeling.

Prepare a Concise Case Summary:

From Our Advocates: Many successful peer-to-peer reviews focus on the patient's specific clinical circumstances rather than general policy requirements. When providers can clearly articulate why this particular patient needs this specific product, medical directors are more likely to approve coverage.
