Submit PA with endocrinologist consultation, lab evidence of hypocalcemia, and documented failure of calcium/vitamin D therapy. Appeals must be filed within 65 days if denied.

Frequently Asked Questions

What if Natpara isn't on Humana's formulary? Request a formulary exception with medical necessity documentation. Include evidence that covered alternatives are inappropriate or have failed.

Can I get expedited approval if my calcium is dangerously low? Yes, request an expedited review if delay could endanger your health. Provide documentation of urgent medical need.

What happens if my appeal is denied? You can request an Independent Review Entity evaluation within 60 days. This provides an unbiased review by independent medical experts.

From our advocates: We've seen cases where patients initially denied for Natpara successfully obtained coverage by working closely with their endocrinologist to document specific complications from conventional therapy—like recurrent kidney stones from high-dose calcium or persistent symptoms despite optimal medical management. The key is comprehensive documentation that directly addresses the payer's specific concerns.


Understanding the complex landscape of specialty drug coverage can be overwhelming, especially when dealing with limited-supply medications like Natpara. Counterforce Health specializes in turning insurance denials into targeted, evidence-backed appeals by analyzing payer policies and coordinating the right clinical documentation to meet each plan's specific requirements.
