Frequently Asked Questions

How long does Humana prior authorization take in New York? Standard processing is up to 30 days for Medicare Advantage plans. Expedited reviews are completed within 24-72 hours for urgent medical needs.

What if Sylvant is not on Humana's formulary? Request a formulary exception with strong medical necessity documentation. Your prescriber must explain why formulary alternatives are unsuitable.

Can I appeal a Humana Medicare denial through New York state? No. Humana Medicare plans must use the federal Medicare appeals process, not New York's external appeal system which only applies to commercial and Medicaid plans.

Do I need step therapy for Sylvant? Sylvant is typically not subject to step therapy due to its specific indication for multicentric Castleman disease, but confirm with your specific Humana plan.

What happens if I'm HIV-positive or HHV-8-positive? Sylvant is not covered for patients who are HIV-positive or HHV-8-positive, as it's only FDA-approved for HIV-negative, HHV-8-negative multicentric Castleman disease.

How do I transfer my prescription to CenterWell Pharmacy? Use the CenterWell Pharmacy website or mobile app to initiate transfers. Some specialty biologics may require new prescriptions from your provider.

When Treatment Gets Complicated: Getting Expert Help

When facing insurance denials for complex treatments like Sylvant, many patients and clinicians find the appeals process overwhelming. Counterforce Health helps patients, clinicians, and specialty pharmacies turn insurance denials into targeted, evidence-backed appeals. The platform analyzes denial letters and plan policies to identify the specific denial basis—whether it's prior authorization criteria, medical necessity requirements, or coverage limitations—then drafts point-by-point rebuttals aligned to the plan's own rules, complete with the right clinical evidence and procedural requirements for your specific situation.

From our advocates: "We've seen Sylvant denials overturned when the appeal included specific lab documentation showing HIV-negative and HHV-8-negative status alongside detailed oncologist notes explaining why the patient's multicentric Castleman disease requires this particular therapy. The key is often in how the medical necessity is presented using the plan's own coverage criteria language."
